W2F11A4718AT3A

Overview

The KYOCERA AVX W2F11A4718AT3A is a surface-mount feedthrough capacitor from the W2F series, housed in an 0805 (2012 metric) package. It features a C0G (NP0) dielectric and offers a capacitance of 470 pF with a tolerance of -20% to +50%. The component has a DC voltage rating of 100 VDC and operates within a temperature range of -55°C to +125°C. Key electrical specifications include a maximum DC resistance of 600 mOhms, an insulation resistance of 1 GOhms, and a current rating of 300 mA. It utilizes four terminals for SMD/SMT mounting.

Feature Summary

• Provides effective electromagnetic interference filtering through its three-terminal feedthrough architecture.
• Maintains stable capacitance performance across wide temperature variations due to C0G dielectric construction.
• Supports high-frequency signal integrity with low parasitic inductance inherent to the feedthrough design.

Applications

• High-frequency circuit noise suppression
• Power line filtering in sensitive electronics
• Signal conditioning in RF applications

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm terminal configuration and packaging type. Ensure the selected variant matches the required capacitance tolerance and voltage rating for the target application. Cross-reference the datasheet for precise mechanical dimensions to validate PCB footprint compatibility before procurement.

Selection Notes

Select this component when a compact surface-mount solution is required for high-frequency noise attenuation. The C0G dielectric ensures minimal capacitance drift over temperature and voltage changes. Consider the 0805 footprint constraints and the specific -20% to +50% tolerance requirements relative to circuit sensitivity.

Part Context

This part belongs to the KYOCERA AVX W2F series of multilayer ceramic feedthrough capacitors. These components are designed to replace traditional wire-wound filters in space-constrained designs. The series provides reliable EMI suppression while maintaining small form factors suitable for modern dense PCB layouts.

Replacement Considerations

Consult official substitution guides for equivalent feedthrough capacitors with matching 0805 footprints and 100V ratings. Verify that alternative parts maintain similar C0G dielectric characteristics and current handling capabilities to ensure circuit performance parity.
