1、 CRH2512F30K0E04Z 2512 30K 1% 2W High Power Resistance Core Parameters Detailed Explanation
CRH2512F30K0E04Z 2512 30K 1% 2W high-power resistor belongs to the CRH series high-power thick film resistor of Tian'er Technology, which focuses on "high power density+high precision+long life" and is specifically designed for applications with limited PCB space but high heat generation. It is suitable for multiple types of products such as fast charging power supply, motor drive, BMS sampling circuit, etc. Its core parameters are disassembled as follows, taking into account both professionalism and practicality, making it convenient for frontline personnel to quickly refer to.
Core electrical parameters (key performance indicators)
As the core competitiveness of high-power resistors, the electrical parameters of CRH2512F30K0E04Z 2512 30K 1% 2W high-power resistors fully comply with industrial standards, and some indicators are superior to ordinary resistors of the same specification:
Resistance and accuracy: The resistance value is 30K Ω (marked as 30K), and the accuracy reaches ± 1% (F level). In the 2512 package resistor with a power level of 2W, this accuracy belongs to the advanced configuration. Ordinary 2W high-power resistors have a precision of ± 5%. The CRH2512F30K0E04Z 2512 30K 1% 2W high-power resistor significantly reduces the error and can meet the high resistance accuracy requirements of circuits such as precision voltage division and current detection, avoiding the impact of resistance deviation on the overall performance of the equipment.
Rated power: 2W (at an ambient temperature of 70 ℃). This is one of the core selling points of the CRH2512F30K0E04Z 2512 30K 1% 2W high-power resistor. The rated power of conventional 2512 packaged thick film resistors is usually 1W. By optimizing the ceramic substrate thermal conductivity layer and resistor paste formula, Tian'er Technology doubled the power density without increasing the package size, achieving a stable output of 2W and effectively solving the pain points of insufficient power and easy heating and damage of small-sized packaged resistors.
Temperature Coefficient (TCR): ± 100ppm/℃, with a working temperature range covering -55 ℃ to+155 ℃. The resistance value can be stably locked within the entire temperature range, even in extreme temperature difference environments such as outdoor low temperature and industrial equipment high temperature operation, there will be no significant resistance drift, ensuring long-term stable operation of the equipment and adapting to various harsh working scenarios.
Rated voltage: Calculated based on resistance and power, the CRH2512F30K0E04Z 2512 30K 1% 2W high-power resistor has a rated voltage of about 24.5V and strong surge voltage tolerance, which can cope with instantaneous voltage fluctuations in the circuit, reduce the probability of resistor breakdown and damage, and improve the overall reliability of the circuit.
Physical and process parameters (adapted for production and installation)
CRH2512F30K0E04Z 2512 30K 1% 2W high-power resistor fully considers production convenience in terms of process and size, compatible with mainstream production processes, and reduces enterprise production costs:
Package size: Standard 2512 package, with specific dimensions of 6.4mm × 3.2mm × 0.55mm, fully compatible with industry standard reflow soldering curves. There will be no issues such as blistering or end detachment when the peak temperature is 260 ℃. It is suitable for automated surface mount production and can directly replace resistors from other brands in the same package without the need to modify PCB design, reducing research and development and production costs.
Material and Craftsmanship: Adopting metal glaze thick film technology, the electrode is coated with tin nickel, which has better resistance to sulfurization than ordinary pure silver electrodes. Even in industrial sulfur-containing gas environments, it can effectively prevent electrode corrosion and extend the service life of resistors; Ceramic substrates have excellent thermal conductivity and can quickly dissipate the heat generated during operation, further improving power stability and service life.
Packaging specifications: Adopting woven tape packaging, 4000 pieces per plate, compatible with automated surface mount equipment, and easy to store and transport, reducing damage during transportation and meeting the needs of large-scale production in enterprises; Small batch procurement can provide bulk packaging, flexibly adapting to scenarios such as research and development sampling, and small-scale trial production.
Reliability and compliance parameters (adapted to multi industry certification requirements)
CRH2512F30K0E04Z 2512 30K 1% 2W high-power resistor has passed multiple industry compliance certifications, and its reliability has been rigorously tested to meet the high-end needs of multiple industries
Environmental certification: fully compliant with RoHS 2.0 and REACH SVHC standards, free of harmful substances such as lead and mercury, and does not require additional environmental testing for export to the European Union, North America, and other regions. It meets global environmental production requirements and is suitable for industries with high environmental requirements such as consumer electronics and medical equipment.
Reliability testing: After 1000 hours of 70 ℃ rated power aging testing, the resistance drift is less than 0.5%, far better than the industry average level; At the same time, through multiple reliability tests such as welding heat resistance, moisture resistance, and vibration resistance, it can adapt to harsh working environments such as long-term continuous operation of industrial equipment and automotive electronic vibration, reducing the probability of equipment failure.
