RN214-0.8-02

Overview

The Schaffner RN214-0.8-02 is a current-compensated common mode filter choke from the RN series, designed for vertical PCB mounting. It features a nominal inductance of 27 mH at a test frequency of 10 kHz and supports a maximum DC current of 0.8 A. The component exhibits a typical DC resistance of 500 mΩ and operates within a temperature range of -40°C to +100°C. Constructed with through-hole pins and UL 94V-0 rated materials, it provides EMC suppression for power lines in environments up to Pollution Degree 2.

Feature Summary

• Current-compensated design for effective common mode noise attenuation
• Vertical board mount configuration utilizing through-hole termination
• Compliant with UL 94V-0 flammability standards for safety

Applications

• Electromagnetic compatibility filtering for power line circuits
• EMI suppression in electronic equipment requiring vertical integration
• Noise reduction in systems operating under Pollution Degree 2 conditions

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as RN214-0.8-02-27M explicitly define the 27 mH inductance value. Confirm that the required current rating of 0.8 A aligns with your circuit's maximum DC load. Ensure the vertical through-hole package fits your PCB layout constraints. Cross-reference the manufacturer datasheet to validate compliance requirements for your target market.

Selection Notes

Select this component when a compact vertical solution is required for common mode interference suppression. The 27 mH inductance offers significant impedance at 10 kHz for effective noise filtering. Consider the 0.8 A current limit to ensure reliable operation without saturation. The wide operating temperature range supports deployment in diverse environmental conditions. Verify that the 500 mΩ DC resistance meets your voltage drop specifications.

Part Context

This part belongs to the Schaffner RN series of current-compensated chokes, engineered for EMC applications. The RN214 variant specifically denotes a vertical mounting style suitable for space-constrained PCB designs. These components are widely utilized in industrial and consumer electronics to mitigate electromagnetic interference on power lines while maintaining signal integrity.

Replacement Considerations

The RN214-0.8-02-27M is a confirmed public substitute part number representing the same electrical characteristics. Verify pin compatibility and mechanical dimensions before substitution. Ensure the replacement maintains the required 0.8 A current rating and 27 mH inductance.
