RFCS04026000DBTTS

Overview

The RFCS04026000DBTTS is a silicon-based radio frequency capacitor manufactured by Vishay Electro-Films. It features a capacitance of 0.6 pF with a tolerance of ±0.1 pF and a temperature coefficient of 100 ppm/°C. Rated for 50 V, the component operates within a temperature range of -55°C to +125°C. Housed in a compact 0402 (1005 metric) surface-mount package measuring 1.02 mm in length, 0.51 mm in width, and 0.38 mm in height, it utilizes SMD/SMT termination. The device is designed for high Q performance in RF applications.

• Radio frequency signal processing
• High-frequency filtering applications

Procurement Notes

This component is officially classified as End-of-Life (EOL) by Vishay Electro-Films. Production has ceased, and availability is restricted or non-existent through standard distribution channels. Procurement should focus on identifying verified replacement parts from the manufacturer's substitution list rather than sourcing this specific obsolete part number.

Selection Notes

Designers requiring this specific capacitance value must transition to alternative components due to the product's discontinued status. Selection criteria should prioritize silicon capacitors or thin-film RF capacitors that match the original 0.6 pF value, 0402 package dimensions, and 50 V rating while ensuring compatibility with existing RF circuit requirements.

Part Context

The RFCS series represents Vishay Electro-Films' line of silicon capacitors, engineered for high-frequency stability and precision. This specific model belongs to the RFCS family, which integrates silicon dielectric technology to provide consistent electrical characteristics across varying temperatures, distinguishing it from traditional ceramic or film alternatives in RF environments.

Replacement Considerations

Vishay provides official substitute part numbers for this obsolete component. Engineers should consult the manufacturer's EOL Product Termination Notice or datasheet for confirmed replacements that maintain equivalent electrical specifications and physical form factors.
