CRH2512F18K0E04Z 2512 18K 1% 2W Ever Ohms High Power Resistance Parameters and Competitive Analysis
In electronic circuits such as industrial control, power modules, and communication equipment that require high power carrying and resistance stability, the CRH2512F18K0E04Z 2512 18K 1% 2W resistor has become the preferred component for many engineers due to its stable performance and high cost-effectiveness. This resistor is developed and produced by Ever Ohms Technology. As one of the core models of the CRH series high-power thick film surface mount resistors, the CRH2512F18K0E04Z 2512 18K 1% 2W resistor fully meets the practical application needs of mid to high end circuits in terms of process design and performance, balancing reliability and cost control. It is the mainstream selection of high-power resistors in 2512 packages on the market. Below, we will comprehensively analyze the CRH2512F18K0E04Z 2512 18K 1% 2W resistor from three dimensions: core parameter disassembly, detailed comparison with competitors, and recommendation from legitimate agents, providing practical reference for procurement and selection.
Firstly, we will break down the CRH2512F18K0E04Z 2512 18K 1% 2W resistor from the core parameter details, so that everyone can clearly understand the core advantages of this product. The CRH2512F18K0E04Z 2512 18K 1% 2W resistor adopts a standard 2512 chip package, with a corresponding metric size of about 6.4mm × 3.2mm. It is a commonly used package for medium to high power chip resistors. Compared with small packages such as 0805 and 1206, the 2512 package has a larger heat dissipation area and can better carry the rated power of 2W, avoiding performance degradation or damage caused by heat accumulation during long-term operation. This is also the basis for the CRH2512F18K0E04Z 2512 18K 1% 2W resistor to achieve stable high-power output.
Resistance and accuracy are one of the core highlights of CRH2512F18K0E04Z 2512 18K 1% 2W resistor. The nominal resistance of this resistor is 18K Ω (18000 Ω), which belongs to the commonly used range of medium to high resistance values. It is suitable for the current limiting, voltage dividing, and load matching needs of most circuits. For example, it is used for current limiting in power circuits to prevent excessive current from damaging subsequent components, and for voltage dividing regulation in signal circuits to ensure stable signal transmission. The precision level reaches 1% (indicated by the "F" in the model), which is much higher than the ordinary 5% precision resistor. It can meet the high precision requirements of industrial automation, precision instruments and other scenarios, without the need to pay an additional cost premium for high-precision resistors, and has outstanding cost-effectiveness.
In terms of power performance, the rated power of the CRH2512F18K0E04Z 2512 18K 1% 2W resistor is 2W, which is a conventional high-power configuration in the 2512 package. By optimizing the thick film material formula and substrate heat dissipation design, Tian'er Technology enables this resistor to stably carry 2W power for a long time at an ambient temperature of 25 ℃. Even in high temperature environments (up to 155 ℃), stable operation can be achieved through power derating, with a minimum operating temperature of -55 ℃, and a wide temperature range to meet the needs of different scenarios. In terms of material, the CRH2512F18K0E04Z 2512 18K 1% 2W resistor adopts ruthenium based oxide thick film technology and high stability ceramic substrate, combined with anti-oxidation end electrodes, which not only improves the heat dissipation performance of the resistor, but also enhances its resistance to moisture and sulfurization. In a humid and hot environment of 85 ℃/85% RH, the resistance drift rate is less than 0.5%, effectively extending the product's service life. At the same time, it meets RoHS and REACH environmental certification and adapts to strict environmental requirements.
In addition, the temperature coefficient (TCR) of the CRH2512F18K0E04Z 2512 18K 1% 2W resistor is controlled at ± 100ppm/℃, which means that within the wide temperature range of -55 ℃ to 155 ℃, the fluctuation of resistance with temperature changes is minimal, ensuring the stability of the circuit in different environments and avoiding performance deviations caused by temperature changes. At the same time, this resistor has a rated voltage of 200V and an instantaneous withstand voltage capability of up to 3000V. It performs well in dealing with transient overloads and is suitable for scenarios such as new energy charging piles and communication base stations that require high voltage stability.
At present, thick film high-power surface mount resistors on the market with specifications consistent with CRH2512F18K0E04Z 2512 18K 1% 2W resistors (2512 package, 18K resistance, 1% accuracy, 2W power) mainly come from well-known brands such as Guoju, Weishi, and Fenghua High tech. The core parameters of each brand's products are basically the same, but there are certain differences in process details, performance emphasis, and price. Below is a detailed comparative analysis.
The first competitor is Guoju RC2512F18K0FT. As a globally renowned supplier of passive components, the core parameters of Guoju's product with the same specifications are the same as CRH2512F18K0E04Z 2512 18K 1% 2W resistor, with the same 2512 package, 18K resistance, 1% accuracy, and 2W power. The main difference between the two lies in temperature coefficient and sulfur resistance. The temperature coefficient of Guoju's product is ± 200ppm/℃, slightly higher than the ± 100ppm/℃ of CRH2512F18K0E04Z 2512 18K 1% 2W resistor, and the resistance stability is slightly inferior. In terms of price, Guoju's product has a 15% -20% higher resistance than CRH2512F18K0E04Z 2512 18K 1% 2W. Its advantage lies in its wide channel coverage, strong product supply stability, and suitability for mass production scenarios that require high supply stability, low temperature coefficient requirements, and sufficient budget.
The second competitor is Weishi PTN2512L1183BGTS. As an international leading electronic component brand, Weishi's core parameters for this packaged product are 18K resistance, 1% accuracy, and 2W power. It uses thin film technology for more precise precision control, but the temperature coefficient is also ± 200ppm/℃, which is on par with Guoju's products. The advantage of the Weishi product lies in its good high-frequency performance and strong anti-interference ability, making it suitable for high-end scenarios such as communication equipment and precision instruments that require high circuit performance. However, its price is the highest among the three competitors, more than 30% higher than the CRH2512F18K0E04Z 2512 18K 1% 2W resistor, and its cost-effectiveness is slightly lower, making it unsuitable for cost sensitive scenarios.
The third competitor is Fenghua High Tech CUH2512F18K0E04Z. As a well-known passive component brand in China, this product has highly consistent resistance parameters with CRH2512F18K0E04Z 2512 18K 1% 2W, with a temperature coefficient of ± 100ppm/℃. The price is also similar to that of the Tian'er product. The main difference between the two lies in the process details and reliability. The anti sulfurization ability of Fenghua High tech's product is slightly weaker, and the resistance drift rate in humid and hot environments is higher than that of CRH2512F18K0E04Z 2512 18K 1% 2W resistor. The stability of long-term operation in harsh environments needs to be improved, and the stock reserve is not as sufficient as that of Tian'er, resulting in relatively longer delivery times.
Overall, CRH2512F18K0E04Z 2512 18K 1% 2W resistor achieves a balance in stability, cost-effectiveness, and adaptability. It not only has the advantage of low-temperature drift of ± 100ppm/℃, but also has strong resistance to vulcanization and moisture. Its price is lower than international brands, and its reliability is better than domestic brands at the same price. It is the preferred choice for most conventional and mid to high end scenarios.
