RN202-2-02-1M1

Overview

The Schaffner RN202-2-02-1M1 is a current compensated common mode choke designed for power line applications. It features an inductance of 1.1 mH at a test frequency of 10 kHz and supports a maximum DC current of 2 A. The component exhibits a maximum DC resistance of 70 mOhms with a tolerance range of -30% to +50%. Constructed with ferrite core material, it utilizes a vertical through-hole mounting style with four pins. The physical dimensions are 18.2 mm in length, 8.8 mm in width, and 13.5 mm in height. It operates within a temperature range of -40°C to +100°C.

Feature Summary

• Provides electromagnetic interference suppression through current compensated common mode filtering.
• Utilizes ferrite core construction for effective high-frequency noise attenuation.
• Designed for vertical printed circuit board mounting via through-hole termination.

Applications

• Power line filtering in electronic equipment
• Electromagnetic compatibility enhancement in industrial systems
• Noise reduction in AC/DC power supply circuits

Procurement Notes

Verify the manufacturer part number RN202-2-02-1M1 against official TE Connectivity or Schaffner documentation to ensure authenticity. Confirm that the component meets required RoHS compliance standards and matches specified electrical parameters, including 1.1 mH inductance and 2 A current rating. Check for any specific ordering suffixes that may alter functional characteristics before finalizing procurement.

Selection Notes

Select this component when a two-line power filter with 1.1 mH inductance and 2 A current capacity is required. Ensure the PCB layout accommodates the 18.2 mm x 8.8 mm footprint and vertical orientation. Verify that the operating environment stays within the -40°C to +100°C temperature range and that the unshielded design does not interfere with adjacent sensitive components.

Part Context

This component belongs to the RN series of common mode chokes manufactured by TE Connectivity / Schaffner. It is categorized under inductors, chokes, and coils, specifically designed as a current compensated choke for vertical PCB mounting. The product serves as a passive filter element for mitigating common mode noise in power distribution networks.

Replacement Considerations

RN202-0.3-02-22M offers similar vertical through-hole mounting but differs significantly in current rating (0.3 A) and inductance (22 mH). RN212-2-02-1M8 provides comparable 2 A current handling but features higher inductance (1.8 mH) and distinct physical dimensions.
