Procurement Notes

Verify the specific suffix codes against official Tusonix documentation to confirm exact electrical tolerances and material specifications. Ensure that the mechanical mounting hole diameter matches the bushing requirements of the target chassis. Confirm compliance with relevant environmental regulations such as RoHS if applicable to the end-use industry. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when high-capacitance values are required in a compact axial form factor for panel-mounted applications. The 500 V rating makes it suitable for higher voltage DC lines where standard ceramic capacitors might fail. Consider the 20 A current handling capability for power distribution networks. Evaluate the physical dimensions to ensure adequate clearance within the enclosure. Compare performance characteristics against alternative feedthrough designs if space constraints are critical.

Part Context

This component belongs to the Tusonix feedthrough capacitor family, designed for EMI/RFI suppression. These filters are commonly used in harsh environments requiring reliable noise reduction. The axial lead configuration allows for easy integration into panel boards. Tusonix specializes in custom and standard filter solutions for defense, aerospace, and industrial sectors. This specific model represents a high-capacitance option within their product line.

Replacement Considerations

Consult official Tusonix substitution guides for verified equivalent part numbers. Generic replacements may not match the precise capacitance tolerance or voltage ratings. Verify mechanical compatibility, including bushing size and lead spacing, before substituting. Ensure that any alternative component meets the same thermal and current specifications to maintain system reliability.
