Designed for high Q factor applications in radio frequency circuits
Compact surface-mount footprint suitable for space-constrained designs

Applications

RF signal coupling and decoupling
Impedance matching networks
Filter circuit implementation

Procurement Notes

This component is currently marked as End-of-Life (EOL) by the manufacturer. Availability is restricted, and sourcing may require checking for limited stock or obsolete inventory through authorized distributors. Verify the specific ordering suffix and RoHS compliance status directly with suppliers before procurement to ensure compatibility with current manufacturing requirements.

Selection Notes

Select this part for applications requiring precise low-picoFarad capacitance in RF environments. Ensure the design accommodates the 0402 package dimensions and the specified operating temperature range. Consider the ±0.1 pF tolerance when designing tight impedance matching criteria. Verify that the 50 V rating meets the circuit's voltage stress requirements.

Part Context

The RFCS series represents Vishay’s silicon capacitor line, offering alternatives to traditional ceramic capacitors in RF applications. These components provide better stability and lower parasitic inductance compared to standard MLCCs. The RFCS04024000DBTWS specifically targets high-frequency circuits where small value precision is critical.
