Procurement Notes

Verify the complete part number including all suffixes against official TDK documentation to ensure exact specification matching. Confirm that the intended application environment aligns with the component's voltage and temperature ratings. Request manufacturer datasheets for detailed mechanical dimensions and soldering profiles prior to integration into production designs.

Selection Notes

Select this component when signal line integrity requires low-capacitance filtering with minimal impact on signal speed. The 0805 footprint offers a balance between size constraints and electrical performance. Ensure the operating voltage remains within the 50 V DC limit to maintain reliability and prevent dielectric breakdown during normal operation.

Part Context

This component belongs to TDK's series of feed-through capacitors engineered for EMI/RFI suppression. These devices utilize internal grounding structures to divert noise currents away from sensitive signal paths.
