4202-021LF

Overview

The 4202-021LF is a low-pass LC (Pi) EMI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance value of 1500 pF and is rated for a maximum DC current of 10 A with a voltage rating of 350 V. Designed for chassis mounting, the component utilizes an axial package configuration with bushing terminals. The filter operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Provides effective electromagnetic interference suppression through a third-order low-pass LC Pi network topology.
• Engineered for high-current applications with a 10 A maximum DC current rating.
• Features robust chassis mounting capabilities via axial bushing terminals for secure installation.

Applications

• Mobile device data line filtering
• Chassis-mounted power supply noise reduction
• Industrial control system EMI suppression

Procurement Notes

Verify the specific capacitance variant against official datasheets, as product listings may reference 1500 pF or 5000 pF configurations for this series. Confirm RoHS3 compliance status and ensure the axial bushing mounting style matches the mechanical design requirements before finalizing procurement orders.

Selection Notes

Select this component when a third-order low-pass response is required for high-current DC lines. Ensure the 350 V voltage rating and 10 A current capacity align with the circuit specifications. Verify that the chassis mounting form factor fits the available enclosure space and thermal management strategy.

Part Context

This component belongs to the 4200 series of feed-through and EMI filters from Tusonix/CTS. These components are designed to attenuate radio frequency interference in power and signal lines. The 4202-021LF specifically addresses scenarios requiring robust chassis integration and significant current handling capability alongside noise filtration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative LC Pi filters from the same manufacturer series only if exact electrical parameters and mounting dimensions match.
