RN114-0.5-02-39M

Overview

The Schaffner RN114-0.5-02-39M is a horizontal common mode choke designed for through-hole PCB mounting. It operates with a maximum DC current of 0.5 A and features an inductance of 39 mH at 1 kHz. The component has a typical DC resistance of 830 mOhm and supports a temperature range from -40°C to +100°C. Its ferrite core construction provides unshielded performance suitable for compact electronic designs requiring effective noise suppression.

Feature Summary

• Horizontal form factor optimized for space-constrained printed circuit board layouts
• Through-hole termination ensures secure mechanical attachment during assembly
• Ferrite core material delivers stable magnetic properties across the operating temperature range

Applications

• Power supply input filtering for consumer electronics
• Noise suppression in industrial control systems
• Signal integrity protection in communication equipment

Procurement Notes

Verify the exact part number against manufacturer documentation to ensure compatibility with specific design requirements. Confirm that the through-hole footprint matches the intended PCB layout. Check regulatory compliance status such as RoHS if required by your application standards. Ensure storage conditions maintain component integrity prior to assembly.

Selection Notes

Select this component when a horizontal orientation is necessary for board stacking or clearance constraints. The 39 mH inductance value targets specific frequency ranges for common mode noise attenuation. Verify that the 0.5 A current rating meets the operational load without saturation. Consider the thermal characteristics relative to ambient operating conditions.

Part Context

This component belongs to the RN series of common mode chokes manufactured by Schaffner EMC Inc., now part of TE Connectivity. The series is engineered for electromagnetic interference suppression in various electronic applications. The RN114 variant specifically addresses needs for higher inductance values in a compact horizontal package format.

Replacement Considerations

Cross-reference with RN116-0.5-02-39M for similar specifications but potentially different physical dimensions. Verify electrical parameters match exactly before substitution. Ensure mechanical fitment is compatible with existing PCB footprints.
