4200-000LF

Overview

The 4200-000LF is a tubular EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It utilizes a Pi filter circuit topology to provide effective electromagnetic interference suppression. The component features a maximum DC current rating of 10 A and a capacitance value of 1500 pF. It operates within a temperature range of 0°C to +125°C and has a maximum DC resistance of 10 GOhms. The unit is housed in a tray package and carries the UNF-2A thread specification.

Feature Summary

• Provides high-performance attenuation for electromagnetic interference using a Pi filter configuration
• Designed for chassis mounting applications with robust thermal stability
• Capable of handling significant direct current loads while maintaining signal integrity

Applications

• Chassis-mounted electronic equipment requiring EMI suppression
• Power supply input filtering for sensitive instrumentation
• Industrial control systems operating in high-interference environments

Procurement Notes

Verify the specific suffix requirements against your design specifications before ordering. Confirm that the UNF-2A threading matches your panel cutout dimensions. Ensure the 10 A current rating and 1500 pF capacitance align with your system's electrical constraints. Check for RoHS compliance documentation if required by your procurement policy. Validate the operating temperature range suitability for your intended environment.

Selection Notes

Select this component when a Pi filter topology is required for superior noise rejection compared to single-capacitor solutions. Consider the 10 A current capacity for power line applications where higher currents are present. Evaluate the physical dimensions and UNF-2A thread compatibility with existing chassis structures. Compare the 1500 pF capacitance value against other series options if different frequency responses are needed.

Part Context

This part belongs to the 4200 series of EMI feedthrough filters from Tusonix/CTS. The series offers various capacitance values and voltage ratings tailored for different shielding requirements. These components are widely used in aerospace, military, and industrial sectors where reliable EMI performance is critical. The tubular form factor allows for direct panel mounting.

Replacement Considerations

Direct substitutes include other parts within the Tusonix 4200 series with matching capacitance and current ratings. Verify thread compatibility and physical dimensions before replacing. Cross-reference with CTS official substitution guides for equivalent performance characteristics.
