W3F11A4708AT1A

Overview

The W3F11A4708AT1A is a surface-mount feedthrough capacitor from the KYOCERA AVX W3F series. It features a capacitance of 47 pF with a C0G (NP0) dielectric, ensuring stable performance across temperature variations. The component supports a DC voltage rating of 100 V and a current rating of 300 mA. It utilizes a 1206 (3216 metric) package with four terminals and a maximum DC resistance of 600 mOhms. Designed for high-frequency applications up to 5 GHz, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective electromagnetic interference filtering through integrated feedthrough architecture
• Maintains capacitance stability using C0G (NP0) ceramic dielectric material
• Supports high-frequency signal integrity with low parasitic inductance design

Applications

• High-speed digital circuit power distribution networks
• RF module decoupling and noise suppression
• Automotive electronics requiring robust EMI protection

Procurement Notes

Verify the specific suffix 'T1A' against official datasheets to confirm tape-and-reel packaging specifications. Ensure compatibility with standard 1206 footprint land patterns. Confirm RoHS compliance status for your region. Validate that the 300 mA current rating meets your circuit requirements. Check for any recent product change notices affecting pinout or materials.

Selection Notes

Select this component when compact size and high-frequency filtering are critical. The 1206 package offers a balance between thermal performance and board space efficiency. The C0G dielectric ensures minimal capacitance drift under varying bias and temperature conditions. Consider the 600 mOhm DCR limit for power loss calculations in high-current paths.

Part Context

This part belongs to the W3F series of three-terminal filter capacitors designed for surface-mount assembly. These components integrate capacitor and inductor functions into a single package to suppress broadband noise. The series is widely used in telecommunications and computing infrastructure where space constraints and signal purity are paramount.

Replacement Considerations

Check for direct substitutes within the W3F series with identical capacitance and package dimensions. Verify equivalent electrical parameters such as voltage rating and current handling before substitution. Ensure mechanical fit and terminal configuration match the existing PCB layout.
