4305-009LF

Overview

The 4305-009LF is an axial lead EMI feedthrough capacitor manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 1500 pF with a voltage rating of 200 V and a current handling capacity of 5 A. The component operates within a temperature range of -55°C to +125°C. It utilizes a solder mount configuration suitable for printed circuit board integration.

Feature Summary

• Provides electromagnetic interference suppression through feedthrough filtering architecture
• Supports high-temperature operation up to 125°C for demanding environments
• Features axial lead construction for standard PCB mounting applications

Applications

• Electronic equipment requiring EMI noise reduction
• Power supply input/output filtering circuits
• Signal line protection in sensitive instrumentation

Procurement Notes

Verify the specific voltage rating requirements against the datasheet, as some sources indicate 200V while others list 300V. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to ordering, as regulatory status can vary by production batch. Ensure the axial package dimensions fit the target PCB layout constraints.

Selection Notes

Select this component when a compact axial feedthrough filter is required for mid-range capacitance values. Compare the 1500 pF specification against system noise profiles to ensure adequate attenuation. Consider the 5 A current rating to verify it meets the circuit's operational load without derating issues at elevated temperatures.

Part Context

This part belongs to the 4305 series of EMI feedthrough filters from Tusonix/CTS. The series offers various capacitance values tailored for different filtering needs. These components are designed to replace traditional discrete capacitor networks with a single, space-saving solution that provides superior high-frequency performance.

Replacement Considerations

Direct substitutes include other 1500 pF axial feedthrough capacitors from Tusonix such as the 4305-008LF or 4305-010LF if available. Verify pin compatibility and thermal ratings before swapping with generic equivalents.
