C20N50Z4B

Overview

The C20N50Z4B is a high-frequency surface-mount RF termination resistor manufactured by TTM Technologies. It provides a nominal resistance of 50 Ohms with a tolerance of 2 percent and a power rating of 20 Watts. The component operates effectively from DC up to 6 GHz. It features an SMD package in the 1210 (3-SMD, No Lead) form factor. The device supports operation across a temperature range suitable for demanding environments, ensuring stable performance in commercial wireless applications.

Feature Summary

• Designed for high-power dissipation in compact surface-mount footprints
• Maintains stable impedance characteristics across wide frequency bands
• Constructed for durability under rigorous operating conditions

Applications

• 5G cellular infrastructure terminations
• LTE network equipment matching
• General-purpose RF circuit load balancing

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with automated pick-and-place equipment regarding the 1210 footprint dimensions. Cross-reference thermal management requirements with system design specifications to guarantee reliable heat dissipation during continuous operation.

Selection Notes

Select this component when a robust 50-ohm load is required for frequencies extending beyond standard microwave ranges. The 20-watt rating allows for significant signal handling capacity within a small board area. Consider the 6 GHz upper frequency limit when designing for advanced wireless standards requiring minimal parasitic effects.

Part Context

This part belongs to the Xinger III series of SMD terminations from TTM Technologies. These components are engineered to replace traditional through-hole resistors in high-density PCB layouts. The series offers improved reliability and consistent performance in commercial wireless bands compared to legacy discrete solutions.

Replacement Considerations

Direct substitutes include other 20W 50-ohm SMD RF terminations from the same manufacturer family, such as the C20A50Z4 or C16A50Z4, provided the frequency response and physical footprint constraints align with the specific application requirements.
