Contact Arrangement:
SPST-NO
Application:
Make/Break Load Switching

R43A series high voltage relays are designed to meet demanding load requirements at higher voltages. While still a compact form factor, the elongated stacked ceramic body allows for increased isolation when compared to the R41A. The RF-rated design ensures exceptional performance in applications requiring precise switching and reliable isolation. Equipped with tungsten contacts, the R43A delivers enhanced make and break load switching capabilities. Common applications include antenna tuning units (ATUs) and high voltage test equipment. Featuring a Single Pole Single Throw, Normally Open (SPST-NO) configuration, this relay offers a simple yet effective solution for isolation, utilizing a single stationary contact to maintain isolation until coil power is applied.
