RN114-2-02

Overview

The Schaffner RN114-2-02 is a power line common mode choke designed for through-hole mounting. It features an inductance of 4.2 mH and supports a maximum DC current of 2 A. The component has a rated AC voltage of 300 V and a typical DC resistance of unspecified low value, optimized for EMI suppression. It operates within a temperature range of -40°C to +100°C and utilizes ferrite core material. The device is unshielded and measures approximately 17.7 x 17.1 x 12.6 mm.

Feature Summary

• Provides effective electromagnetic interference (EMI) suppression on power lines
• Designed for through-hole PCB integration with robust mechanical stability
• Utilizes ferrite core technology for high-frequency noise attenuation

Applications

• General-purpose electronic circuit filtering
• Power supply input stages requiring EMI reduction
• Equipment adhering to ENEC, UR, and VDE safety standards

Procurement Notes

Verify the specific part number suffix against official Schaffner documentation to confirm exact inductance tolerance and pin configuration. Ensure compatibility with existing PCB footprint dimensions and thermal management requirements. Cross-reference approval agency listings such as ENEC, UR, and VDE if regulatory compliance is mandatory for the target application environment.

Selection Notes

Select this component when a 4.2 mH common mode choke is required for 2 A applications. Consider the 300 V AC rating and operating temperature range relative to system constraints. Evaluate the through-hole package size against available board space. Confirm that the unshielded design meets spatial and coupling requirements compared to shielded alternatives.
