Procurement Notes

Verify the specific suffix 'F' against the official TDK datasheet to confirm the termination type and reel packaging configuration. Ensure the selected variant matches the required 12V rating and 200mA current capacity for the target application. Cross-reference the RoHS compliance status with the latest manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when a low-capacitance (70 pF) solution is required to preserve signal integrity while attenuating high-frequency noise. The 0805 package size suits dense PCB layouts. Confirm that the 50 MHz cutoff frequency aligns with the operational bandwidth of the protected circuit to prevent unwanted signal degradation.

Part Context

This part belongs to the TDK MEM series of passive components, specifically categorized under EMI filter circuits. It is engineered for use in environments requiring reliable noise suppression without significant impact on data transmission speeds. The component adheres to standard industry dimensions for surface-mount technology.

Replacement Considerations

Consult the official TDK cross-reference guide for verified substitutes. Ensure any replacement maintains the 70 pF capacitance and 50 MHz cutoff frequency specifications to guarantee equivalent filtering performance.
