RN102-1-02

Overview

The Schaffner RN102-1-02 is a horizontal through-hole common mode choke from the RN series. It features an inductance of 3 mH and a rated current of 1 A at 40°C. The component operates within a temperature range of -40°C to +100°C. It utilizes a four-pin PCB terminal configuration for mounting.

Feature Summary

• Provides electromagnetic interference suppression via common mode filtering
• Designed for horizontal printed circuit board integration
• Constructed for reliable operation across wide thermal environments

Applications

• Power line filtering in electronic equipment
• EMI reduction in AC/DC power supplies
• Signal integrity maintenance in industrial control systems

Procurement Notes

Verify the specific suffix (e.g., -3M0) against the datasheet to confirm exact inductance values, as the base model number may represent a family. Ensure the horizontal package style matches the PCB footprint requirements. Confirm compliance with relevant safety standards for the intended application environment before finalizing procurement.

Selection Notes

Select this component when a 3 mH inductance and 1 A current rating are required for horizontal mounting. Consider the -40°C to +100°C operating range for environmental suitability. Evaluate the physical dimensions against available board space to ensure proper clearance and mechanical stability during assembly.

Part Context

This part belongs to the Schaffner RN series of EMC chokes, which are widely used for noise suppression in power circuits. The RN102 variant specifically denotes a horizontal form factor with four pins, distinguishing it from other mounting styles within the broader product lineup designed for compact electronic assemblies.

Replacement Considerations

Direct substitutes include RN102-1-02-3M0. Verify pin compatibility and electrical ratings before substitution.
