Procurement Notes

Verify RoHS compliance status as sources indicate non-compliance for this specific suffix variant. Confirm package dimensions and terminal configuration against schematic requirements. Ensure operating temperature range meets system environmental specifications. Validate current ratings against peak load conditions to prevent thermal failure during procurement validation.

Selection Notes

Select this component when a surface-mount Pi-filter solution is required for 100 V applications. The 4000 pF capacitance and 0.1 µH inductance define the cutoff frequency characteristics. Compare physical footprint constraints against available board space. Consider the -20% to +80% tolerance if precise capacitance values are critical for circuit performance.
