Procurement Notes

Verify RoHS compliance status as specific listings indicate non-compliance for this variant. Confirm thread specifications match panel cutouts. Check manufacturer lead times as items may be made-to-order. Ensure voltage and current ratings align with system requirements before integration.

Selection Notes

Select this component when 2700 pF capacitance and 100 V rating are required for feed-through filtering. Compare insertion loss characteristics against other series members like 4403-030 or 4403-040 if different capacitance values are needed. Verify physical size constraints fit the 0.125-inch diameter housing.

Part Context

This part belongs to the Tusonix 4403 series of EMI feed-through filters manufactured by CTS Electronic Components. The series includes various capacitance values such as 100 pF and 27000 pF, sharing similar axial bushing form factors and mounting threads for consistent mechanical integration.

Replacement Considerations

Direct substitutes include 4403-033LF which shares identical electrical parameters. Other series variants like 4403-030 (100 pF) or 4403-040 (27000 pF) offer different capacitance but same mechanical interface.
