W2F11A1018AT3A

Overview

The W2F11A1018AT3A is a surface-mount feedthrough capacitor from the KYOCERA AVX W2F series. It features a capacitance of 100 pF with a tolerance of -20% to +50%. The device has a DC voltage rating of 100 V and a current rating of 300 mA. Its maximum DC resistance is 600 mOhms. The component utilizes C0G (NP0) dielectric material for stable performance across a temperature range of -55°C to +125°C. It is housed in an 0805 (2012 metric) package with four PCB pads, measuring 2.01 mm in length, 1.25 mm in width, and 1.14 mm in height.

Feature Summary

• Provides electromagnetic interference filtering through a three-terminal feedthrough architecture integrated into a compact surface-mount footprint.
• Maintains capacitance stability under varying thermal conditions due to the use of C0G (NP0) dielectric material.

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive electronic circuits
• EMI suppression in automotive electronics operating within specified temperature ranges

Procurement Notes

Verify the specific suffix 'T3A' against official datasheets to confirm packaging configuration, as standard designations may vary between distributors. Ensure the selected variant matches the required reel or cut-tape specifications for your assembly process. Cross-reference the manufacturer part number directly with KYOCERA AVX documentation to avoid substitution errors with similar series components like W2H.

Selection Notes

Select this component when a low-inductance, high-current capable filter is required for 100 VDC applications. The 300 mA current rating distinguishes it from lower-capacity variants in the same family. Consider the 0805 footprint constraints and the specific -20% to +50% tolerance requirements for your circuit design before finalizing the bill of materials.

Part Context

This component belongs to the W2F series of surface-mount feedthrough capacitors manufactured by KYOCERA AVX. The series is designed for EMI suppression in space-constrained applications. Similar parts include W2F11A1018AT1F and W2F11A1018AT1A, which share identical electrical characteristics but may differ in packaging formats such as tape-and-reel versus cut-tape configurations.

Replacement Considerations

W2F11A1018AT1F and W2F11A1018AT1A are electrically equivalent alternatives within the same series. Verify that the replacement variant's packaging format aligns with your manufacturing equipment capabilities before substitution.
