RN114-0.8-02

Overview

The Schaffner RN114-0.8-02 is a two-line common mode choke from the RN series, designed for PCB board mounting with horizontal orientation. It features a current rating of 0.8 A and an inductance of 27 mH at 10 kHz. The component operates within a temperature range of -40°C to +100°C and meets UL 94V-0 flammability standards. It is rated for 300 VDC and complies with PD2 pollution degree requirements.

Feature Summary

• Provides electromagnetic interference suppression through common mode filtering for two-line circuits.
• Utilizes a through-hole terminal connection method suitable for printed circuit board assembly.
• Constructed with materials compliant with RoHS directives and lead-free specifications.

Applications

• Power supply input stages
• Battery charger circuits
• Portable electronic devices

Procurement Notes

Verify the specific suffix (e.g., -27M) against the required inductance value, as the base part number may denote a family rather than a single specification. Confirm that the 0.8 A current rating aligns with the application's peak load requirements. Ensure the through-hole package dimensions fit the designated PCB footprint. Check for any updated regulatory compliance certificates relevant to the target market.

Selection Notes

Select this component when a compact, board-mount solution is required for low-current applications. The 27 mH inductance offers significant attenuation for high-frequency noise. Consider the physical height constraint of approximately 13.5 mm during mechanical design. Verify that the operating voltage does not exceed the 300 VDC limit under all transient conditions.

Part Context

This component belongs to the Schaffner RN series of EMC chokes, which are engineered for general-purpose noise suppression. The series provides various inductance values and current ratings to suit different power line filtering needs. These components are widely used in consumer electronics and industrial equipment to meet electromagnetic compatibility standards.

Replacement Considerations

RN114-0.8-02-27M is a confirmed substitute with identical electrical characteristics. Other variants in the RN114 series may offer different inductance or current ratings but share the same form factor. Verify pinout compatibility before substituting with non-Schaffner equivalents.
