1、 Detailed Explanation of Core Parameters of CRH2512J8K20E04Z Product
The model name of CRH2512J8K20E04Z directly reflects its key specifications. CRH "represents the high-power thick film resistor series of Tian'er Technology; 2512 "refers to its packaging size, which is 6.35mm in length and 3.20mm in width, which is the basic physical size for achieving a heat dissipation capacity of 2W rated power; J "represents a resistance accuracy of ± 5%; 8K20 "refers to a nominal resistance of 8.2 kiloohms (8.2K Ω); E04 "is a specific product code; The "Z" symbol complies with environmental standards.
The complete electrical and physical parameters are as follows:
Rated power: Can withstand a power dissipation of 2W continuously at an ambient temperature of+70 ° C. This is its core indicator as a high-power resistor.
Resistance and accuracy: The nominal resistance is 8.2K Ω, and the tolerance is strictly controlled within ± 5%.
Working temperature range: from -55 ° C to+155 ° C, ensuring reliable operation in harsh temperature environments.
Temperature coefficient (TCR): ± 100 ppm/° C. This means that for every 1 ° C change in temperature, the maximum relative change in resistance value is 0.01%, which is a good level for thick film resistors.
Maximum operating voltage: up to 200V, with a certain surge current tolerance.
Packaging and process: Adopting 2512 standard surface mount packaging, manufactured based on mature thick film technology. Using high thermal conductivity alumina ceramic as the substrate material, a resistor paste is deposited through screen printing technology to form a resistor, which is then sintered at high temperature to form a resistor. The terminal electrode adopts a three-layer structure (such as silver/nickel/tin) to ensure welding reliability and long-term oxidation resistance.
Environmental Protection and Certification: The product complies with RoHS and REACH environmental standards, and some series have passed AEC-Q200 automotive certification, suitable for high reliability fields such as automotive electronics.
