W3F11A4708AT1F

Overview

The W3F11A4708AT1F is a surface-mount feedthrough capacitor from the KYOCERA AVX W3F 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. Constructed with C0G (NP0) dielectric, it offers low equivalent series resistance of 600 mOhms maximum and supports a current rating of 300 mA. The component utilizes a 1206 (3216 metric) package with four terminals for SMD/SMT mounting.

Feature Summary

• Provides electromagnetic interference filtering through three-terminal feedthrough architecture
• Maintains stable capacitance characteristics using C0G (NP0) dielectric material
• Supports high-frequency signal integrity with low parasitic inductance design

Applications

• RF circuit filtering in communication systems
• Power supply decoupling in sensitive electronic modules
• Signal conditioning in smart meter applications

Procurement Notes

Verify the specific suffix 'T1F' against the manufacturer's datasheet to confirm tape-and-reel packaging specifications. Ensure the -20%/+50% tolerance aligns with circuit requirements. Confirm RoHS3 compliance status if restricted substances are regulated in the target market. Cross-reference the 1206 footprint dimensions with PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a compact surface-mount solution is required for high-frequency noise suppression. The 100V rating suits low-voltage DC lines, while the 300mA current handling capability supports moderate load conditions. The wide operating temperature range ensures reliability in harsh environments. Consider the specific capacitance tolerance limits during schematic design to account for potential variation in filter performance.

Part Context

This part belongs to the W3F series of three-terminal feedthrough capacitors designed for surface-mount technology. These components integrate filtering capabilities directly into the package structure, reducing board space compared to discrete RLC networks. The series is engineered for applications requiring effective EMI/RFI attenuation in compact form factors.

Replacement Considerations

The W3F41A4708AT1F shares identical electrical specifications but is marked as obsolete. Verify availability of active equivalents within the same series or package type if long-term supply stability is required.
