4300-025LF

Overview

The 4300-025LF is an axial lead EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. This component functions as a low-pass filter designed to suppress electromagnetic interference in power and signal lines. It features a discoidal capacitor construction with axial leads for through-hole mounting. The device is rated for a maximum DC current of 5 A and has a voltage rating of 50 V. It operates within a temperature range from -55 °C to +125 °C. The unit is supplied in bulk packaging.

Feature Summary

• Provides effective attenuation of high-frequency noise on single-conductor lines
• Utilizes axial lead configuration for secure PCB or panel mounting
• Constructed with robust materials suitable for harsh thermal environments

Applications

• Power supply input filtering
• Signal line noise suppression
• Electronic equipment chassis grounding points

Procurement Notes

Verify the specific capacitance value and tolerance requirements against the official datasheet before ordering, as variations may exist within the series. Confirm that the axial lead spacing matches your board layout or connector specifications. Ensure the 50 V rating and 5 A current capacity are sufficient for the target circuit conditions. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a compact, high-current feedthrough solution is needed for low-voltage applications. The 50 V rating limits its use to low-voltage DC systems. Consider the physical dimensions and lead length for mechanical fitment. Compare performance against other series like 4306 or 4400 if higher voltage or different capacitance values are required.

Part Context

This part belongs to the Tusonix 4300 series of EMI feedthrough filters. These components are widely used in industrial and commercial electronics for noise reduction. The manufacturer, Tusonix, is known for specialized filtering solutions under the CTS umbrella. The axial format distinguishes it from radial or flange-mounted alternatives in the same product family.

Replacement Considerations

Direct substitutes must match the 50 V rating, 5 A current capacity, and axial form factor. Verify equivalent capacitance values to ensure similar filtering characteristics. Cross-reference with other manufacturers offering axial feedthrough capacitors with identical electrical ratings and mechanical dimensions.
