The design of this resistor fully considers the requirements of high reliability applications and plays a key role in power management, industrial control, and automotive electronic modules.
Deep analysis of key parameters of CRH2512F82K0E04Z
To fully understand the performance positioning of this CRH2512F82K0E04Z resistor, it is necessary to disassemble its key parameters:
Physical packaging and power: The 2512 package (metric 6432) is used, with dimensions of 6.4mm x 3.2mm, which is one of the packages that can achieve high power density in surface mount resistors. Its rated power is 2W, usually referring to the continuous bearing capacity at an ambient temperature of 70 ° C. In practical design, attention must be paid to the power derating curve, as the allowable power consumption will correspondingly decrease when the ambient temperature rises.
Electrical performance: The nominal resistance value is 82k Ω, with an accuracy of ± 1%, which meets the requirements for resistance consistency in the vast majority of industrial applications. Its operating temperature range typically covers -55 ° C to+155 ° C, ensuring stability in harsh temperature environments. The temperature coefficient (TCR) of this type of resistor is an important indicator, although it is not directly reflected in the basic model, the high-power resistor series of Tian'er usually provides good temperature stability.
Reliability and Certification: Tian'er Technology's products are generally certified by quality management systems such as ISO9001. For automotive grade applications, their corresponding product lines will also pass AEC-Q200 certification, which is crucial for automotive electronics that pursue high reliability, such as BMS battery management systems and ECUs. Resistors such as CRH2512F82K0E04Z are also designed with a focus on surge resistance, capable of withstanding short-term overvoltage shocks.
Comparative analysis of market competitors
In the thick film resistor market with 2512 package, 82k Ω, 2W, and 1% precision, CRH2512F82K0E04Z faces competition from multiple domestic and foreign brands. Understanding competitors can help make more appropriate material selection decisions.
