RFCS04024700CJTWS

Overview

The RFCS04024700CJTWS is a silicon capacitor manufactured by Vishay Electro-Films. It features a capacitance of 4.7 pF with a tolerance of ±5%. The device has a voltage rating of 25 V and operates within a temperature range of -55°C to 125°C. It utilizes a 0402 (1005 Metric) surface-mount package with dimensions of 1.02 mm x 0.51 mm and a height of 0.41 mm. The component is RoHS compliant and classified under ECCN EAR99.

Feature Summary

• Utilizes silicon technology for stable capacitance performance across wide temperature ranges.
• Designed for high-frequency applications due to low equivalent series inductance characteristics inherent to the silicon construction.
• Compliant with RoHS3 standards for environmental safety.

Applications

• High-frequency circuit filtering
• RF signal coupling and decoupling
• Miniaturized electronic assemblies requiring small form factor capacitors

Procurement Notes

This component is obsolete and no longer manufactured. Verification of availability should focus on existing stock from authorized distributors or secondary market suppliers. Ensure that any sourced units are genuine and have not been subject to unauthorized handling. Cross-reference with approved substitute part numbers such as those from KYOCERA AVX if new production is required for current designs.

Selection Notes

Select this component only for legacy system maintenance or repair where original specifications must be maintained. Due to its discontinued status, it is unsuitable for new product development. Engineers should evaluate alternative silicon capacitors or standard ceramic types that offer similar electrical parameters and package dimensions to ensure long-term supply chain stability.

Part Context

The RFCS series represents Vishay's line of silicon capacitors, known for superior frequency response compared to traditional ceramic capacitors. This specific model belongs to the 0402 footprint family, targeting space-constrained designs. The 'WS' suffix typically denotes a specific tape and reel packaging configuration for automated assembly processes.

Replacement Considerations

The document identifies 04023J4R7BBSTR from KYOCERA AVX as a similar substitute part number. Users should verify electrical compatibility and pin-out alignment before substitution.
