RFCS04021000CBTWS

Overview

The RFCS04021000CBTWS is a silicon-based radio frequency capacitor manufactured by Vishay Electro-Films. It features a capacitance of 1 pF with a tolerance of ±5% and a voltage rating of 50 V. The component operates within a temperature range of -55°C to +125°C and utilizes a 0402 (1005 metric) surface-mount package.

Feature Summary

• Utilizes silicon thin-film technology for stable high-frequency performance
• Designed for compact surface-mount applications in RF circuits
• Provides consistent electrical characteristics across wide temperature ranges

Applications

• High-frequency signal coupling and decoupling
• RF impedance matching networks
• Filter circuit implementation in communication devices

Procurement Notes

Verify the specific suffix 'CBTWS' against official Vishay documentation to confirm exact tolerance, voltage, and packaging specifications. Ensure compatibility with standard reflow soldering profiles for 0402 silicon capacitors. Confirm RoHS compliance status through current datasheets before integration into final assemblies.

Selection Notes

Select this component when a precise 1 pF capacitance is required in ultra-compact RF designs. The 50 V rating supports moderate voltage applications. Consider the 0402 footprint constraints and ensure PCB layout accommodates the specific parasitic inductance inherent to silicon thin-film structures at target frequencies.
