R43C Series High Voltage Relay
The R43C series high voltage relay is specially designed to meet the demanding load requirements in high voltage applications. It maintains a compact form factor, but its extended and layered ceramic body provides superior insulation. This makes it more advantageous compared to the R41A model.
Thanks to its RF-compatible design, it delivers high performance in applications requiring precise switching while ensuring reliable isolation. Equipped with tungsten contacts, it offers enhanced make/break performance and supports long service life.
These features make it suitable for use in applications such as antenna tuning units (ATU) and it is also widely preferred in high voltage testing equipment.
The SPDT (Single Pole Double Throw) configuration includes both Normally Open (NO) and Normally Closed (NC) contact sets. This allows the relay to offer two different circuit states within a single unit. When the coil is energized or de-energized, continuity is maintained by switching between these two contacts.
