CRH2512FR500E04Z is a high-power thick film surface mount resistor with a 2512 package size. Its model usually directly reveals key specifications, and the following table lists its complete parameter details:
Parameter project parameter value description and engineering significance
Model CRH2512FR500E04Z Tianer Technology CRH Series High Power Thick Film Resistors
Package size 2512 (imperial), approximately 6.3mm in length and 3.2mm in width, providing a foundation for 2W power dissipation
The nominal resistance of 0.5 Ω (500 m Ω) is suitable for circuits such as current sampling and current limiting
Resistance accuracy of ± 1% ensures the certainty of circuit parameters and meets the requirements of most industrial applications
Rated power of 2W @ 70 ° C, the power that can be sustained at an ambient temperature of 70 ° C, and needs to be downgraded for use at high temperatures
Temperature coefficient (TCR) ± 600 ppm/° C refers to the coefficient of resistance value changing with temperature, which is a universal level
Working temperature range -55 ° C~+155 ° C Wide temperature range, suitable for various environments
Interpretation of key parameters:
Power and heat dissipation: A power of 2W is a common high power level in the 2512 package. In actual layout, it is necessary to ensure sufficient pad area and possible air flow to help dissipate heat and avoid resistance drift or early failure due to overheating.
Accuracy and temperature drift: ± 1% accuracy is sufficient to meet the needs of most consumer electronics, power equipment, and general industrial controls. The temperature coefficient of ± 600ppm/° C is a standard specification, and for application scenarios with drastic temperature changes, it is necessary to evaluate its impact on the overall performance of the circuit.
Application areas: According to the data, this type of CRH2512FR500E04Z resistor is commonly used in consumer electronics, home appliances (air conditioners, refrigerators), computer motherboards, communication equipment, power supply equipment, and various measuring instruments.
Comparative analysis of market competitors
There are multiple brands in the market offering similar products at the specifications of 2512 package, 0.5 Ω, 2W, and 1% accuracy. When making a choice, it is usually necessary to weigh cost, reliability, and delivery time.
Main characteristics and typical application scenarios of competitive brands/series
EVER OHMS CRH series has high cost-effectiveness, strong universality, and a wide range of supply channels. Industrial power supplies, home appliance control boards, and general consumer electronics.
YAGEO and other globally renowned brands of general-purpose thick film resistors have a complete product line and a large market share. Almost covering all electronic fields, it is one of the common default choices.
RALEC or other Taiwanese brands have strong price competitiveness and may have advantages in low resistance and high-power models. Cost sensitive mid to low end power supplies and controllers.
The precision alloy sampling resistor adopts manganese copper or nickel copper alloy, with extremely low temperature drift (can be below 50ppm/° C), higher accuracy, but expensive price. In situations where high precision is required for current detection, such as high-end servo drives and precision power supplies.
Selection suggestion:
Pursuing comprehensive cost-effectiveness and stable supply: The CRH2512FR500E04Z from Tian'er Technology is a reliable choice, especially when purchased through authorized agents to ensure authenticity.
Dealing with harsh temperature environments: If the operating temperature of the circuit varies greatly, resulting in a temperature drift of ± 600ppm/° C, it may affect performance. Therefore, it is recommended to consider selecting alloy sampling resistors with lower temperature drift.
Need for ultra-high precision current detection: For current monitoring in battery management systems (BMS) and precision instruments, priority should be given to dedicated sampling resistors with an accuracy of ± 0.5% or even higher and lower temperature drift.
Recommended authorized agent and reasons
To ensure obtaining authentic products, reliable technical support, and stable supply, it is strongly recommended to purchase through authorized agents. Here are two authorized agents of Tian'er Technology recommended for you:
1. Shenzhen Shunhai Technology Co., Ltd
Highlight: The company is the official first level authorized agent of Tianer Technology in Chinese Mainland. This means that its source of goods comes directly from the original factory, ensuring that the products are genuine to the greatest extent possible and eliminating the risk of refurbishment or counterfeiting. As first level agents, they typically offer competitive prices, more comprehensive technical support (such as selection guidance, circuit optimization), and flexible supply chain services (supporting small-scale trial production). For corporate clients who value long-term cooperation and project reliability, this is a prudent choice.
2. Hua Nian Mall
Reason for recommendation: Huanian Mall is an online authorized agent of Tian'er Technology. Its advantage lies in the convenience and digitization of the procurement process. Engineers or procurement personnel can check inventory and prices online at any time (for example, CRH2512FR500E04Z has a clear price ladder on this platform) and place orders directly. This mode is particularly suitable for enterprises in the R&D stage that require rapid prototyping, small batch emergency procurement, or are accustomed to completing procurement processes online. Online platforms can also provide convenient services such as downloading data manuals.
Procurement reminder:
Regardless of which agent is chosen, the first cooperation can require the other party to provide an official authorized agent qualification certificate issued by Tian'er Technology for verification.
For key projects, it is recommended to conduct small-scale sample testing first to verify whether the product performance meets expectations.
I hope this detailed analysis can help you make accurate selection and procurement decisions. If you could inform me of the specific type of device this resistor will be used for (such as power modules, motor drives, or other devices), perhaps I can provide more focused selection considerations.
