Procurement Notes

Verify the specific suffix codes on the component marking against official Panasonic datasheets to confirm exact capacitance tolerance and terminal configuration. Ensure the operating voltage derating aligns with the manufacturer's guidelines for the intended ambient temperature. Cross-reference the manufacturing date code to check for any recent material updates or supply chain notices published by Panasonic Industry.

Selection Notes

Select this component based on its rated voltage margin relative to peak circuit voltages and its physical footprint constraints within the assembly. Consider the thermal management requirements of the installation site, as self-healing capabilities may be affected by extreme heat accumulation. Validate that the lead form factor matches the PCB layout specifications to avoid mechanical stress during soldering or operation.

Part Context

This part belongs to Panasonic's general-purpose high-voltage film capacitor lineup, often designated under specific series codes like UP or similar variants depending on the region and era. These components are widely used in automation controls and industrial machinery where reliability is critical. The model number structure typically indicates voltage rating, capacitance value, and case size, adhering to Panasonic's standard naming conventions for passive components.

Replacement Considerations

Direct replacements must match the capacitance value, voltage rating, and physical dimensions exactly. Verify that alternative brands offer comparable self-healing properties and insulation resistance levels. Check for equivalent pulse current ratings if the application involves high di/dt environments. Consult Panasonic's official substitution guide for any recommended cross-references within their own product portfolio.
