Procurement Notes

Verify the specific suffix 'T1F' against official datasheets to confirm packaging configuration, as suffixes may indicate variations in reel or cut-tape specifications. Ensure compatibility with RoHS3 standards if required by your manufacturing environment. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select this component when a low-profile, three-terminal filter is needed for high-frequency noise attenuation in space-constrained designs. The 0805 footprint allows for dense PCB layouts while maintaining adequate grounding via the dedicated ground terminal. Consider the 300 mA current rating and 600 mOhm DCR limits to ensure the component can handle the expected signal currents without excessive insertion loss or thermal issues.

Part Context

This part belongs to the KYOCERA AVX W2F series of surface-mount feedthrough capacitors. These components are engineered to provide superior high-frequency performance compared to standard two-terminal capacitors by utilizing a three-terminal structure that minimizes parasitic inductance. The series is designed for applications demanding reliable EMI suppression in small form factors.

Replacement Considerations

The W2F15C4738AT1A is documented as a parameter-equivalent alternative within the same series. Verify that the packaging suffix difference does not impact mechanical integration or reflow soldering profiles. No other substitutes are confirmed in public documentation.
