W2F11A4708AT1A

Overview

The W2F11A4708AT1A is a surface-mount feedthrough capacitor from the KYOCERA AVX W2F series. It features a capacitance of 47 pF with a tolerance of -20% to +50%. The device has a DC voltage rating of 100 V and operates within a temperature range of -55°C to +125°C. Utilizing C0G (NP0) dielectric, it offers low ESR of 600 mOhms and handles 300 mA current. Packaged in an 0805 (2012 metric) footprint with four terminals, it supports frequencies up to 5 GHz.

Feature Summary

• Provides electromagnetic interference suppression through integrated feedthrough filtering architecture
• Maintains stable capacitance characteristics across wide temperature variations using C0G dielectric
• Enables high-current signal transmission with minimal resistive loss via low DCR design

Applications

• High-frequency signal line filtering in communication equipment
• Power supply decoupling for sensitive RF circuits
• EMI suppression in automotive electronic control units

Procurement Notes

Verify the specific suffix 'AT1A' against official datasheets to confirm packaging and tape specifications. Ensure compatibility with standard 0805 reflow soldering profiles. Confirm RoHS compliance status for your region before integration into final assemblies.

Selection Notes

Select this component when space-constrained designs require combined power delivery and noise filtering. The 0805 package suits dense PCB layouts. Choose based on required capacitance stability and current handling capabilities rather than general-purpose filtering needs.

Part Context

This part belongs to the W2F series of multilayer ceramic feedthrough capacitors. These components integrate passive filtering directly into the signal path, reducing board space compared to discrete LC filters. The series is designed for high-reliability applications requiring consistent performance under thermal stress.

Replacement Considerations

W2F11A4708AT1F is listed as a parameter-equivalent alternative by distributors.
