W3F45C4718AT1F

Overview

The W3F45C4718AT1F is a surface-mount feed-through capacitor manufactured by KYOCERA AVX. It features a capacitance of 470 pF with a DC voltage rating of 50 VDC. The component utilizes an X7R dielectric material and is housed in a 1206 (3216 metric) package, measuring 3.2 mm in length, 1.6 mm in width, and 1.27 mm in height. It has four terminals for SMD/SMT mounting and offers a capacitance tolerance of -20% to +50%. The device is designed for high-frequency filtering applications within electronic circuits.

Feature Summary

• Provides effective electromagnetic interference suppression through feed-through architecture
• Utilizes X7R ceramic dielectric for stable performance across temperature variations
• Supports surface mount technology for automated assembly integration

Applications

• High-frequency signal line filtering
• Power supply noise reduction in compact modules
• RF circuit impedance matching and decoupling

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact electrical tolerances and termination specifications. Ensure compatibility with PCB footprint dimensions, particularly the 1206 package size. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement to meet manufacturing standards.

Selection Notes

Select this component when a compact feed-through filter is required for 50V DC applications. The X7R dielectric provides adequate stability for general-purpose filtering. Consider the -20% to +50% tolerance range during circuit design to ensure performance margins are met under varying conditions.

Part Context

This part belongs to the W3F series of three-terminal feed-through capacitors from KYOCERA AVX. These components are engineered for high-frequency noise suppression in space-constrained environments. The series supports various capacitance values and voltage ratings within standard surface-mount packages.

Replacement Considerations

Cross-reference with other W3F series parts or equivalent 1206 feed-through capacitors from other manufacturers. Verify that substitute components match the 470 pF capacitance, 50 VDC rating, and X7R dielectric characteristics to maintain circuit functionality.
