The C10A50Z4 is a surface-mount RF termination (50 ohm load resistor) used in high-frequency microwave and RF systems. It is designed to absorb RF power and eliminate signal reflections in transmission lines, ensuring impedance matching and system stability in RF circuits.

This component is commonly used in telecom, avionics RF systems, and microwave modules, especially in applications involving couplers, isolators, and test equipment where unused RF ports must be properly terminated.

Key features include:

50 Ω RF termination resistor (matched load)
Power rating: 10 W
Frequency range: DC to 3 GHz
Alumina (Al₂O₃) ceramic substrate
Thick-film resistive element
Surface-mount (SMD) RF component
Low VSWR (< ~1.25 typical) for minimal signal reflection
Used in RF chains, isolators, hybrid couplers, and test loads
RoHS compliant, high-reliability design
Stable performance across -55°C to +125°C operating range
