Description
This is Film Chip Resistor. CRCW0402 is a thick film chip resistor series available in a compact 0402 package, designed for general-purpose and high-reliability applications with enhanced power handling capability. It features a robust construction with double-sided printed resistive elements, protective overglaze, and excellent pulse load performance. This resistor series is widely used across automotive, industrial, and commercial electronic circuits requiring stable and compact resistive components.
Features
- Excellent pulse load capability
- Enhanced power rating compared to standard 0402 resistors
- Double-sided printed resistor element for improved reliability
- Protective overglaze for environmental durability
- Ni barrier layer with pure tin plating for solder compatibility
- Compatible with lead-free and lead-containing soldering processes
- Stable performance under varying thermal conditions
Design Notes
- Ensure adequate PCB copper area to improve heat dissipation and maintain film temperature limits
- Consider derating the power based on ambient temperature and thermal resistance
- Pulse load conditions should be evaluated against application-specific surge requirements
- Use proper soldering profiles to maintain integrity of the Ni barrier and tin layer
- Avoid placing near heat-generating components to prevent resistance drift
How to Choose This Part
- Select based on required resistance value and tolerance
- Verify power rating with appropriate derating for thermal conditions
- Choose for compact designs requiring high reliability in small footprint
- Consider pulse load capability for transient-heavy applications
Applications
- Automotive electronics
- Industrial control systems
- Commercial electronic devices
- High power density circuit designs

- CRCW0603 series for higher power requirements
Application Information:
When the resistor dissipates power, a temperature rise above the ambient temperature occurs, dependent on the thermal resistance of the assembled resistor together with the printed circuit board. The rated dissipation applies only if the permitted film temperature is not exceeded.
