RFCS04021200BJTT1

Overview

The RFCS04021200BJTT1 is a silicon-based radio frequency capacitor manufactured by Vishay Electro-Films. It features a capacitance of 12 pF with a tolerance of ±5% and a voltage rating of 16 V. The component utilizes a 0402 (1005 metric) surface-mount package, measuring 1.02 mm in length, 0.51 mm in width, and 0.41 mm in height. It operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Utilizes silicon thin-film technology for stable RF performance
• High Q factor suitable for high-frequency applications
• Compact 0402 surface-mount footprint

Applications

• RF circuit filtering
• Impedance matching networks
• DC blocking in RF signal paths

Procurement Notes

This component is officially obsolete and no longer manufactured by Vishay. Procurement is restricted to existing stock or secondary market sources. Verify part authenticity and condition carefully when sourcing from non-authorized distributors. Check for available substitutes from other manufacturers if new production is required.

Selection Notes

Select this part only if legacy compatibility is mandatory due to its obsolete status. For new designs, consider alternative silicon capacitors with similar electrical specifications and package dimensions. Ensure the replacement supports the required 16 V rating and 12 pF capacitance within the specified temperature range.

Part Context

Part of the RFCS series of silicon capacitors designed for RF applications. This specific model represents a 12 pF variant in the 0402 package. The series is known for small size and high stability compared to traditional ceramic capacitors in RF environments.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific obsolete model. Designers should evaluate equivalent silicon capacitors from other vendors that match the 12 pF value, 16 V rating, and 0402 package constraints.
