4202-050LF

Overview

The 4202-050LF is a third-order LC (Pi) low-pass EMI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 5000 pF and supports a maximum DC current of 10 A with a voltage rating of 100 V to 200 V depending on the specific datasheet reference. The component utilizes an axial bushing package for chassis mounting, measuring 7.34 mm in diameter and 11.89 mm in length. It operates within a temperature range of -55°C to +125°C and provides significant attenuation, specified at 65 dB @ 100 MHz in related series documentation.

Feature Summary

• Third-order LC Pi-filter topology for enhanced high-frequency noise suppression
• Chassis-mount axial bushing design for secure panel installation
• Capacitive filtering element rated for 5000 pF capacitance
• High current handling capability suitable for power line applications

Applications

• Mobile device data lines requiring EMI protection
• Power supply input filtering for electronic equipment
• Chassis-mounted interference suppression systems

Procurement Notes

Verify the exact voltage rating and RoHS compliance status against the latest manufacturer datasheet, as source materials indicate variations between 100V/ROHS3 and 200V/non-RoHS configurations for similar part numbers. Confirm the specific attenuation value required for your frequency spectrum. Ensure the axial bushing dimensions match your chassis cutout requirements before finalizing procurement orders.

Selection Notes

Select this component when a third-order low-pass response is necessary for superior attenuation compared to single-stage feedthrough capacitors. The axial bushing form factor is ideal for direct panel mounting where space constraints allow for the 7.34 mm diameter. Ensure the operating environment stays within the -55°C to +125°C range and that the 10 A current rating exceeds the maximum expected load current.

Part Context

This component belongs to the 4200 series of LC Pi filters from Tusonix/CTS. It differs from simple feedthrough capacitors by incorporating internal inductive elements to create a multi-stage filtering effect. This series is designed for robust EMI/RFI suppression in industrial and commercial environments, offering higher isolation than standard capacitive filters.

Replacement Considerations
