RFCS04022000DBTTS

Overview

The RFCS04022000DBTTS is a silicon-based radio frequency capacitor manufactured by Vishay Electro-Films. It features a capacitance of 0.2 pF with a tolerance of ±0.1 pF and a voltage rating of 50 V. The component utilizes a 0402 (1005 metric) surface mount 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. This device is designed for high-frequency applications requiring stable performance.

Feature Summary

• Utilizes silicon thin-film technology for consistent RF performance
• High stability with low parasitic effects in compact form factor
• Robust construction suitable for demanding thermal environments

Applications

• RF matching networks
• High-frequency signal processing circuits
• Wireless communication modules

Procurement Notes

This component is officially classified as End-of-Life (EOL) and is no longer manufactured by Vishay. Procurement is restricted to existing stock or third-party distributors. Verification of part authenticity and storage conditions is critical due to the discontinued status. Buyers should confirm lead times and availability directly with suppliers, as inventory levels fluctuate rapidly. Replacement strategies should be prioritized given the production halt.

Selection Notes

Designers seeking this specific 0.2 pF value must account for its EOL status. Alternative selection should focus on silicon capacitors from other manufacturers that offer similar capacitance, voltage ratings, and 0402 packaging. Key parameters to match include tolerance, temperature coefficient, and RF characteristics. Cross-referencing datasheets for equivalent parts ensures functional compatibility while mitigating supply chain risks associated with obsolete components.

Part Context

The RFCS series represents Vishay's line of silicon capacitors, offering advantages over traditional ceramic types in terms of stability and size. These components are part of the broader Vishay Electro-Films portfolio, which specializes in thin-film technologies. The RFCS04022000DBTTS specifically targets niche RF applications where precise, small-value capacitance is required in minimal space, distinguishing it from general-purpose capacitors.
