For industrial and automotive electronic designs that require high power density and reliability, Ever Ohms' CRH2512FR680E04Z high-power thick film chip resistor is a market validated choice. Below, we will provide a detailed analysis of its key parameters, technical advantages, and offer reliable procurement channel analysis.
Analysis of Core Parameters of CRH2512FR680E04Z
This resistor belongs to the Tian'er CRH series, and its design achieves a rated power of 2W in a 2512 standard package size (6.4mm × 3.2mm), balancing space and power consumption requirements.
The following is a detailed explanation of its main technical parameters:
Specific specifications and impact of parameter categories
Package and power 2512 package, rated power 2W @ 70 ℃ standard size provides high power carrying capacity, which helps simplify PCB layout.
The resistance value and precision resistance value are 0.68 Ω (680m Ω), with a tolerance of ± 1%, suitable for applications that require precise current sampling, such as motor drive and power management.
The temperature coefficient (TCR) ± 600 ppm/℃ indicates that the resistance value changes little with temperature and can remain stable within a wide temperature range of -55 ℃ to+155 ℃.
The key reliability has strong anti surge capability, with an instantaneous withstand voltage of up to 2000V, which can withstand the instantaneous high voltage impact in scenarios such as motor start stop and power transient, improving the robustness of the system.
Environmental protection and certification comply with RoHS and REACH, and have passed AEC-Q200 automotive certification to meet international environmental standards. They are also qualified to enter the fields of automotive electronics and high reliability industrial applications.
>Please note: According to data from multiple component stores, the resistance tolerance indicated by model "CRH2512FR680E04Z" is ± 1%. If you need a model with a tolerance of 5%, you may need to search for other models in the Tian'er CRH series with the code "J" level.
Technical advantages and comparison with competitors
The core advantage of CRH2512FR680E04Z lies in its use of thick film technology. By high-temperature sintering on an alumina ceramic substrate, a resistance layer with a thickness of up to 100 μ m is formed, which achieves higher power density and stronger surge resistance while ensuring near thin film resistance accuracy, and is more cost-effective.
Compared with similar domestic and foreign competitors, its positioning is clear:
Compared to international brands such as Vishay CRCW series, under similar electrical performance, this resistor from Tian'er usually has better cost-effectiveness and more flexible supply cycle, providing a reliable choice for cost sensitive projects.
Compared to ordinary thick film resistors, it performs more outstandingly in terms of accuracy (± 1%), temperature coefficient (± 600ppm/℃), and surge resistance, making it more suitable for high demand scenarios such as automotive electronics (BMS battery management), industrial frequency converters, and 5G base station power supplies.
