Type
High-power thick film chip resistor
The CRH series features "power-enhanced" thick film construction, delivering 2W rated load capacity in the standard 2512 footprint—roughly double the capability of conventional 2512 chip resistors. The 357R resistance value sits in the mid-range band, suitable for feedback network voltage division and low-current sensing applications.
Typical Applications
This 2512 357R 2W resistor is widely used across:
Power management & battery protection: Switch-mode power supplies, DC-DC converters, Li-ion battery protection boards
Motor drives: DC motor speed control, stepper motor drivers, brushless motor controllers
Industrial automation: PLC signal conditioning, 4-20mA current loop load matching
Automotive electronics: ECU current limiting, BMS voltage sensing in new energy vehicles
Communication equipment: Base station power supplies, server 48V bus parallel current sharing
LED lighting: Constant-current drive feedback networks for high-power LED systems
Design Considerations
Power derating: The 2W rating applies at 70°C ambient; above this temperature, usable power must be derated per the characteristic curve. A 30%-50% design margin is recommended.
Pad design: To achieve full 2W dissipation, the total solder pad and adjacent trace copper area per termination should be no less than 300mm².
Pulse handling: In switch-mode power and motor drive circuits with transient surges, single-pulse energy must be evaluated against device limits.
Tolerance selection: ±1% tolerance suits most industrial and consumer scenarios; for precision current sensing, metal foil alternatives with tighter tolerance may be considered.
