W3F11A4718AT1F

Overview

The W3F11A4718AT1F is a three-terminal feedthrough capacitor from the KYOCERA AVX W3F series, designed for surface mount applications. It features a 470 pF capacitance with C0G (NP0) dielectric characteristics and a DC voltage rating of 100 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 measuring 3.2 mm x 1.6 mm x 1.27 mm, it offers a tolerance of -20% to +50%. Key electrical parameters include a maximum DC resistance of 600 mOhms, an insulation resistance of 1 GOhm, and an effective frequency range up to 5 GHz.

Feature Summary

• Three-terminal design provides superior high-frequency noise suppression compared to standard two-terminal capacitors by minimizing parasitic inductance.

Applications

• High-frequency signal filtering in RF circuits
• Power supply decoupling for sensitive electronic components
• EMI suppression in communication equipment

Procurement Notes

Verify the specific suffix AT1F against official datasheets to confirm reel packaging and tape specifications. Ensure the requested quantity aligns with standard factory pack sizes, typically 1000 units per reel. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to ordering.

Selection Notes

Select this component when low parasitic inductance is critical for high-frequency performance. The three-terminal structure effectively grounds noise while maintaining signal integrity. Consider the 1206 footprint constraints and the 100V DC rating relative to circuit requirements before implementation.

Part Context

This part belongs to the W3F series of three-terminal filter capacitors. These components are engineered for robust EMI/RFI suppression in space-constrained surface mount designs. The series utilizes stable C0G dielectrics to maintain consistent capacitance values across varying temperatures and bias conditions.

Replacement Considerations

Cross-reference with other W3F series variants such as W3F11A2218AT1F or W3F11A1018AT1F if different capacitance values are required. Verify pinout compatibility and thermal characteristics when substituting with similar three-terminal feedthrough capacitors from other manufacturers.
