RFCS04023900CJTWS

Overview

The RFCS04023900CJTWS is a silicon capacitor from the Vishay Electro-Films RFCS series. It features a capacitance of 3.9 pF with a tolerance of ±5% and a voltage rating of 25 V. The component utilizes a 0402 (1005 metric) surface-mount package, measuring 1.02 mm in length and 0.51 mm in width, with a maximum height of 0.41 mm. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Utilizes silicon dielectric technology for stable performance across wide temperature ranges.
• Designed for high-density surface-mount applications with a compact 0402 footprint.

Applications

• High-frequency circuit filtering
• RF signal coupling and decoupling
• Precision timing circuits

Procurement Notes

Verify the specific suffix 'W' against official Vishay documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with standard reflow soldering profiles for thin-film silicon capacitors. Confirm RoHS compliance status through current manufacturer declarations prior to integration.

Selection Notes

Select this component when a low-capacitance value near 4 pF is required for RF matching networks. The 0402 size suits space-constrained designs. Consider the 25 V rating and ±5% tolerance for precision applications requiring stable silicon-based dielectric characteristics over industrial temperature extremes.

Part Context

This part belongs to the RFCS series of silicon capacitors manufactured by Vishay Electro-Films. These components are designed as alternatives to traditional ceramic capacitors in high-frequency applications, offering superior stability and lower parasitic effects in small surface-mount packages.
