## Functions

1. RF DC Block: Widely used in RF circuits to block DC voltage while allowing high-frequency RF / millimeter-wave AC signals to pass through.

2. High-speed Signal Coupling: Coupling transmission for high-speed differential, microwave and millimeter-wave signals.

3. RF Impedance Matching: Impedance matching for microwave and millimeter-wave circuits.

4. Bypass / Decoupling: High-frequency decoupling beside RF ICs.

> 

> Core Advantages: Capacitance has minimal variation with voltage and temperature, low aging drift; ultra-low parasitic inductance ESL at high frequencies, much lower loss than NP0/COG MLCCs at tens of GHz.

## Application Scope

- Optical communication: TOSA/ROSA optical subassemblies, TIA transimpedance amplifiers, silicon photonic modules CPO/NPO

- Microwave / Millimeter-wave RF: Sub-6G, 77GHz automotive radar, broadband RF test instruments

- High-speed SerDes, high-speed data interfaces

- Broadband RF front-end circuits up to 100GHz

> 

> Suitable for high-frequency designs requiring stable low capacitance and ultra-low parasitic parameters; not intended for low-frequency high-capacity power energy storage.

XBSC0402AR050GA01 is a Murata XBSC series silicon capacitor in 0402 package, rated 0.5pF / 50V with maximum frequency up to 100GHz. It features ultra-low ESL and tiny capacitance drift over voltage and temperature. Commonly used for RF DC blocking and high-speed signal coupling in millimeter-wave and optical TOSA/ROSA modules, delivering far better high-frequency performance than ordinary MLCCs.
