CRH1206F6K20P05Z 1206 6.2K 0.5W Ever Ohms Resistor Parameter Specification

1. Product Overview

The CRH1206F6K20P05Z is a high-power thick film chip resistor manufactured by Ever Ohms Technology (Taiwan). As part of the CRH series, this component features a 1206 package, 6.2KΩ nominal resistance, 0.5W power rating, and ±1% tolerance. Compared to standard 1206 chip resistors (typically rated at 0.25W), the CRH1206F6K20P05Z delivers double the power handling capability within the same footprint, making it suitable for circuit designs with elevated thermal and power dissipation requirements.
Ever Ohms has optimized the resistive paste formulation and ceramic substrate thermal structure for the CRH series, achieving higher power density while maintaining compact dimensions. These resistors are widely deployed in power management, industrial control, telecommunications equipment, and automotive electronics.

3.1 Power Derating

The 0.5W rating is specified at 70°C substrate temperature. Above 70°C, power must be derated per the datasheet curve, reaching zero at 155°C. Designers are advised to maintain adequate margin, avoiding continuous full-power operation to improve reliability and extend service life.

3.2 Temperature Coefficient

Since 6.2KΩ falls within the 10Ω to 1MΩ range, this model features a TCR of ±100 PPM/°C. Referenced to 25°C, the total resistance variation across the full -55°C to +155°C range is approximately ±1.3%, which, combined with the ±1% initial tolerance, remains within acceptable limits for most industrial-grade circuit designs.

4. Physical Dimensions

The CRH1206F6K20P05Z uses the standard 1206 SMD package:

The terminals feature a three-layer structure (nickel barrier layer, tin plating) for excellent solderability and thermal resistance. Recommended PCB pad dimensions are 1.90mm × 3.50mm with a 0.15mm stencil thickness.

6. Typical Applications

• Power Modules: DC-DC converter voltage dividers, feedback networks, dummy loads
• Industrial Control: PLC I/O circuits, sensor signal conditioning, motor drive current limiting
• Telecommunications: Base station power supplies, optical module interfaces, RF termination
• Automotive Electronics: On-board chargers, BMS, body control modules
• Consumer Electronics: Adapters, smart home appliances, audio amplifiers
• LED Lighting: Constant current drivers, overvoltage protection, surge suppression

7. Design Considerations

1. Power Margin: Recommended operating power ≤70% of rating (≤0.35W) to minimize temperature rise.
2. Thermal Layout: Ensure adequate copper area on PCB pads; add thermal vias for high-power applications.
3. Pulse Handling: Thick film technology has limited pulse energy capability; evaluate for high-pulse scenarios.
4. Precision Requirements: ±1% tolerance suits most circuits; consider TCR 叠加 effect for precision divider applications.
5. Drop-in Replacement: Directly replaces standard 1206 6.2K 0.25W resistors with no PCB modification needed.
