RFCS04028200CJTTS

Overview

The RFCS04028200CJTTS is a silicon capacitor from Vishay Electro-Films, designed for high-frequency applications. It features a capacitance of 8.2 pF with a tolerance of ±5%. The device is rated for a maximum voltage of 25 V and utilizes a compact 0402 (1005 Metric) surface-mount package. Dimensions are specified as 1.02 mm in length and 0.51 mm in width. The component operates within a temperature range extending up to 125°C. It is RoHS compliant and lead-free, suitable for integration into dense circuit boards requiring stable RF performance.

Feature Summary

• Utilizes silicon technology for superior high-frequency stability compared to traditional ceramic capacitors.
• Compact 0402 surface-mount footprint enables high-density board layouts without compromising electrical performance.
• Low equivalent series resistance (ESR) and inductance (ESL) characteristics support efficient signal integrity in RF circuits.

Applications

• RF matching networks in wireless communication devices
• Decoupling and bypass applications in high-speed digital circuits
• Filtering components in radio frequency infrastructure

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability through authorized distributors or approved substitute components listed by Vishay. Ensure that any replacement parts maintain identical capacitance, voltage rating, and package dimensions to preserve circuit functionality. Check for RoHS compliance documentation if required by specific project standards.

Selection Notes

Select this component when small physical size and high Q-factor are critical for RF performance. The 8.2 pF value and 25 V rating define its operational limits; ensure these align with circuit requirements. Consider the 0402 package constraints regarding soldering profiles and thermal management. Evaluate alternative silicon capacitors from the same family if supply chain continuity is a concern due to the product's end-of-life status.

Part Context

This component belongs to the RFCS series of silicon capacitors manufactured by Vishay Electro-Films. Silicon capacitors offer distinct advantages over multilayer ceramic capacitors (MLCCs), particularly in maintaining stable capacitance values across varying frequencies and temperatures. The series is engineered for demanding RF and microwave applications where parasitic effects must be minimized.

Replacement Considerations

The datasheet indicates this product is no longer manufactured. Review official Vishay documentation for confirmed substitute part numbers. Substitutes must match the 8.2 pF capacitance, 25 V rating, and 0402 package. Verify that alternative silicon capacitors provide comparable ESR/ESL performance to ensure seamless integration.
