Nidec Copal CRFS RF Slide Switch

In the field of radio frequency design, maintaining signal integrity during switching is a significant challenge. The CRFS series addresses this by utilizing a specialized internal architecture that provides excellent high-frequency characteristics up to 2 GHz. The Nidec Copal CRFS RF Slide Switch allows for seamless transitions between signal paths, making it highly effective for mode selection or antenna switching in portable devices.

One of the key advantages of this switch is its subminiature footprint, which allows for high-density PCB placement. Despite its small size, it features a twin-contact mechanism that ensures stable electrical connection and long-term reliability. Furthermore, the switch is available in both 1-pole 2-contacts (SPDT) and 1-pole 3-contacts (SP3T) versions, providing flexibility for various circuit logic requirements. Whether integrated into wireless communication modules or high-end measurement instruments, the CRFS series delivers professional-grade RF performance with the convenience of automated surface-mount assembly.
