Procurement Notes

Verify the complete part number including suffixes against official TDK documentation to ensure correct capacitance, tolerance, and termination specifications. Confirm that the required packaging format matches project needs, as availability varies between cut tape, reel, and Digi-Reel options. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance status or recommended soldering profiles prior to final procurement decisions.

Selection Notes

Select this component when designing circuits that require precise low-capacitance filtering for high-speed signals while maintaining strict automotive reliability standards. The 0603 package size is suitable for applications with limited board real estate. Ensure the operating voltage remains below the 50 V DC rating and verify that the system's current requirements do not exceed the specified limits for the three-terminal structure.
