4202-051LF

Overview

The 4202-051LF is an LC (Pi) EMI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance value of 5000 pF and a rated voltage of 200 V. The component supports a maximum DC current of 10 A and operates within a temperature range of -55°C to +125°C. It utilizes a third-order low-pass topology with axial bushing mounting. The package dimensions are 0.250 inches in diameter by 0.468 inches in length.

Feature Summary

• LC Pi filter topology for effective EMI suppression
• Third-order low-pass filtering characteristics
• Axial bushing installation design

Applications

• Mobile device data lines
• Chassis-mounted electronic systems
• EMI/RFI filtering applications

Procurement Notes

Verify the specific suffix requirements for RoHS compliance when ordering. Confirm that the 200V rating aligns with system voltage constraints. Ensure mechanical compatibility with the axial bushing mounting style. Check for lead-free specifications if required by environmental regulations. Validate the 10A current handling capability against load requirements.

Selection Notes

Select this component for applications requiring robust chassis-mounted EMI filtration. The LC Pi topology offers superior attenuation compared to simple feedthrough capacitors. Consider the physical size constraints due to the bushing mount. Evaluate the 5000 pF capacitance value for appropriate cutoff frequencies. Ensure the operating temperature range meets environmental demands.

Part Context

This part belongs to the Tusonix 4200 series of EMI filters. It is distinct from standard feedthrough capacitors by its integrated LC structure. The series provides various capacitance and voltage ratings for diverse filtering needs. It is designed for high-reliability industrial and commercial environments.

Replacement Considerations

Direct substitutes include other 5000 pF LC Pi filters with similar voltage and current ratings. Verify pinout and mounting hole dimensions for mechanical fit. Compare insertion loss specifications at target frequencies. Ensure thermal performance matches the original design requirements.
