The W3F15C2238AT3A is a surface-mount feedthrough capacitor from the KYOCERA AVX W3F series. It features a capacitance of 22 nF with an X7R dielectric and a DC voltage rating of 50 V. The component utilizes a three-terminal structure in a 1206 (3216 metric) package, measuring 3.2 mm in length, 1.6 mm in width, and 1.27 mm in height. It supports a current rating of 300 mA and has a maximum DC resistance of 600 mOhms. The device operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.
Verify the specific suffix 'T3A' against official datasheets to confirm packaging configuration, as it differs from standard tape-and-reel designations. Confirm that the three-terminal variant matches the required footprint and grounding scheme for the target PCB layout. Ensure compatibility with the intended operating temperature range and voltage derating requirements before finalizing procurement.
Select this component when low parasitic inductance is critical for high-frequency noise attenuation. The three-terminal design offers superior performance compared to two-terminal alternatives by providing a direct ground path. Consider the 1206 footprint constraints and the 300 mA current handling capability relative to the circuit's operational demands.
This part belongs to the W3F series of multilayer ceramic SMD feedthrough capacitors. The series is engineered for applications requiring effective electromagnetic interference mitigation. The W3F designation specifically indicates a three-terminal configuration, distinguishing it from the two-terminal W2F series while sharing similar electrical characteristics and material technologies.
W3F15C2238AT1F is documented as a parameter-equivalent substitute.
