RFCS04022700BJTT1

Overview

The RFCS04022700BJTT1 is a silicon-based radio frequency capacitor manufactured by Vishay Electro-Films. It features a capacitance of 27 pF with a tolerance of ±5% and a breakdown voltage rating of 10 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. The device is RoHS compliant and classified under ECCN EAR99.

Feature Summary

• Utilizes silicon thin-film technology for stable RF performance
• Designed for high-frequency circuit applications
• Supports surface-mount PCB assembly

Applications

• High-frequency signal processing circuits
• RF filter networks
• Impedance matching networks

Procurement Notes

This component is officially listed as obsolete and no longer in production by the manufacturer. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific lot date code and storage conditions due to the end-of-life status. Availability is limited to existing inventory only, and long-term supply continuity cannot be guaranteed through standard manufacturing channels.

Selection Notes

Engineers selecting this part should account for its discontinued status when designing new products. The fixed 27 pF value and 10 V rating suit specific low-voltage RF environments. Due to the 0402 footprint, board space is constrained. Designers should evaluate thermal management requirements within the -55°C to +125°C operating range and ensure compatibility with standard SMT reflow processes for thin-film silicon capacitors.

Part Context

The RFCS series represents Vishay's line of silicon RF capacitors, offering alternatives to traditional ceramic or film types in high-frequency applications. This specific model belongs to the 0402 form factor, providing compact integration for modern electronics. The series is characterized by consistent electrical properties across temperature variations, supporting reliable operation in demanding RF environments.

Replacement Considerations

The document identifies 06033K270GBTTR by KYOCERA AVX as a similar substitute part number. Note that this alternative uses a 0603 package, requiring layout modification compared to the original 0402 footprint. Verification of electrical equivalence and mechanical fit is required before substitution.
