RFCS04023000DBGWS

Overview

The RFCS04023000DBGWS is a silicon-based radio frequency capacitor manufactured by Vishay Electro-Films. It features a capacitance of 0.3 pF with a tolerance of ±0.1 pF and a voltage rating of 50 V. The component utilizes an SMD/SMT 0402 (1005 metric) package, measuring 1.02 mm in length, 0.51 mm in width, and 0.38 mm in height. It operates within a temperature range of -55°C to +125°C and exhibits a temperature coefficient of 100 PPM/°C.

Feature Summary

• Utilizes silicon thin-film technology for stable RF performance
• Designed for high-frequency applications requiring precise capacitance
• Compatible with standard surface-mount assembly processes

Applications

• RF circuit impedance matching networks
• High-frequency signal coupling and decoupling
• Microwave filter components

Procurement Notes

Verify the specific suffix 'GWS' against official Vishay documentation to confirm packaging and compliance details. Confirm current lifecycle status as availability may vary. Ensure compatibility with existing PCB footprint dimensions before integration into new designs.

Selection Notes

Select this component when a low-value, high-precision capacitance is required for RF paths. The 0402 package offers space efficiency. Consider the 100 PPM/°C temperature coefficient for thermal stability requirements in the target operating environment.
