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

Alternative / Equivalent Products

• RC0402 series (Yageo)
• ERJ-2 series (Panasonic)
• RK73 series (KOA Speer)
• 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.

• Low noise performance (≤ 1.5 µV/V for R > 1 MΩ)
• Excellent temperature stability
• High reliability due to protective lacquer coating (light-blue)
• Resistant to cleaning solvents (IEC 60068-2-45 compliant)
• Compatible with both Pb-free and leaded soldering processes

Construction Details

• Resistive element: deposited metal alloy film
• Substrate: high-grade ceramic body
• Trimming: helical groove for precise resistance adjustment
• Leads: tinned electrolytic copper, welded to end caps

• Rated power: ~0.25W (at 70°C ambient, for SFR16S)
• Low voltage coefficient and excellent long-term stability

Functional Description

• Provides precise resistance for current limiting, voltage division, and signal conditioning
• Low noise makes it suitable for analog and precision circuits
• Metal film structure ensures minimal drift over time and temperature

Design Notes

• Prefer metal film over carbon film for precision and low-noise applications
• Ensure power derating above 70°C ambient
• Maintain adequate spacing for high-voltage applications
• Avoid excessive mechanical stress during PCB assembly
• Consider TCR impact in precision analog circuits

Typical Applications

• Precision analog circuits
• Voltage dividers and reference networks
• Signal conditioning and filtering
