Product Number Decoding
CRH2512F820KE04Z is a standard model code from Ever Ohms' CRH series of high-power thick film chip resistors. CRH denotes the High Power Thick Film series; 2512 indicates the imperial package size (metric: 6.4mm×3.2mm); F represents ±1% tolerance; 820K is the nominal resistance of 820kΩ; E04Z is the factory specification code covering packaging and compliance information.
Product Features
This resistor is manufactured using thick film technology on an aluminum oxide ceramic substrate. Key parameters include: 2512 package, 820kΩ resistance, ±1% tolerance, 2W rated power (at 70℃), ±100ppm/℃ TCR, 200V maximum working voltage, and -55℃ to +155℃ operating temperature range. The 2W power rating doubles the typical 1W capacity of standard 2512 thick film resistors.
Applications
The 820kΩ high resistance combined with 2W power handling makes this component suitable for power supply management (snubber/bleeder resistors in switching power supplies), industrial controls (VFDs, servo drives), automotive electronics (on-board chargers, BMS), communication equipment (base station power units), measurement instruments (meters, navigation devices), and consumer electronics (motherboards, adapters).
Advantages
Key strengths include: power density doubling versus standard 2512 resistors without increasing PCB footprint; ±100ppm/℃ TCR ensuring stability across a wide temperature range; ±1% precision meeting most industrial and automotive requirements; cost-effective thick film technology; and compliance with RoHS, REACH, ISO-9001, ISO-TS16949, and AEC-Q200 standards.
Market Positioning
The CRH series is positioned in the industrial-grade and automotive-grade markets, targeting "high power density + wide-temperature stability" applications. Under the trend of domestic substitution, CRH series leverages thick film cost advantages combined with AEC-Q200 certification to occupy a significant position in the mid-power thick film resistor market.
