W3F15C2238AT1A

Overview

The KYOCERA AVX W3F15C2238AT1A is a surface-mount feedthrough capacitor designed for high-frequency noise suppression. It features a 22 nF capacitance with X7R dielectric material, rated for 50 VDC. The component operates within a temperature range of -55°C to +125°C and supports a current rating of 300 mA. Housed in a compact 1206 (3216 metric) package with four terminals, it exhibits a maximum DC resistance of 600 mOhms and an insulation resistance of 1 GOhm. Capacitance tolerance is specified as -20% to +50%.

Feature Summary

• Utilizes a unique feedthrough structure to provide low parallel inductance.
• Delivers excellent decoupling capabilities for signal integrity.
• Offers robust performance across a wide industrial temperature range.

Applications

• Smart meter applications
• Alternate energy systems
• High-frequency noise suppression circuits

Procurement Notes

Verify the specific suffix 'T1A' 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 the target assembly process. Cross-reference terminal dimensions and pad layout during PCB design to match the 1206 footprint requirements precisely.

Selection Notes

Select this component when low parasitic inductance is critical for effective high-frequency filtering. The X7R dielectric provides stable capacitance characteristics over the operating temperature range. Consider the 300 mA current rating and 600 mOhm DCR limits to ensure the component can handle the expected load without excessive voltage drop or thermal issues in the circuit design.

Part Context

This part belongs to the W3F series of surface mount feedthrough filters from KYOCERA AVX. The series is engineered for applications requiring superior electromagnetic interference suppression in compact spaces. The W3F line includes various capacitance values and package sizes, maintaining consistent electrical performance metrics across the family while adapting to different board space constraints.

Replacement Considerations

W2F15C2238AT1A is listed as a parameter equivalent substitute. Verify package compatibility, as the W2F series typically utilizes a 0805 footprint compared to the 1206 size of the W3F series. Electrical parameters such as capacitance, voltage rating, and current handling should be confirmed identical before substitution.
