4. Technical Advantages
High Power Density in Compact Package
Standard 2512 thick film resistors typically offer 1W power rating. The CRH series achieves 2W in the same package through optimized thick film paste formulation, improved ceramic substrate thermal pathways, and enhanced multilayer termination electrode design. This allows engineers to double power capacity without increasing PCB footprint.
Wide Temperature Range Operation
The CRH series supports an operating temperature range of -55℃ to +155℃ with TCR控制在 ±100ppm/℃. Resistance drift remains below 0.5% under extreme conditions, ensuring long-term circuit stability.
Superior Surge Withstanding and Reliability
The thick film process delivers excellent pulse withstand capability, handling pulse current impacts up to 100A within 5ms. The porous thick film structure provides robust thermal shock resistance and survives short-term overload conditions without damage. AEC-Q200 automotive-grade certification qualifies the series for demanding applications such as automotive electronics.
5. Applications
With its 2512 package, 357Ω resistance, and 2W power rating, CRH2512F357RE04Z is widely used in:
-
Power Management: Start-up circuits, RC snubber networks, and power MOSFET gate drive current limiting in switching power supplies, AC-DC and DC-DC converters
-
Industrial Control: Power divider and current sensing circuits in frequency inverters and servo drives
-
Automotive Electronics: High-voltage sensing in BMS battery management systems and OBC on-board chargers, ECU auxiliary circuits
-
Communication Equipment: Current limiting and voltage divider circuits in base station power supplies and network switches
-
Medical Devices: Signal conditioning and divider networks in CT scanners, ultrasound machines, and defibrillators
