The Series 420/422 relays are magnetic-latching, TO-5 relays designed for low-level switching applications. They feature discrete diodes for coil suppression and polarity reversal protection, making them suitable for high-density PC board mounting.
Key Features
These relays offer low intercontact capacitance and contact circuit losses, making them excellent ultraminiature RF switches for frequency ranges up to the UHF spectrum. They are also ideal for applications where power dissipation must be minimized, as they can be operated with a short duration pulse and do not require external holding power after the contacts have transferred.
Environmental and Physical Specifications
The relays operate in a temperature range of -65°C to +125°C and can withstand vibration up to 30 g’s and shock up to 100 g’s. They have a hermetically sealed enclosure with a maximum weight of 0.10 oz (2.84g).
The Series 420/422 relays are available in various coil voltage options and have a typical RF performance curve. They also have detailed electrical specifications, including contact arrangement, rated duty, contact resistance, and coil operating power.
