TO-5 CASE RELAY
SPDT
Product Description
Series
1MA1
A series of ultra miniature hermetically sealed relays constructed in a transistor style case, providing superior performance and established reliability
characteristics. Available in a variety of sensitivities contact configurations and hybrid improvements, to provide a most versatile element to the circuit
designer.
The following construction features ensure the highest reliability in extreme environments:
-
All welded relay construction
-
Cleaning and sealing techniques ensures maximum internal cleanliness
-
Low level to 1 ampere switching
-
1 form C, SPDT contacts, special metal alloy with gold plating
-
Frame design and force / mass ratio provides exceptional shock and vibration immunity
Low intercontact capacitance and contact circuit losses, provides also a reliable switching functions in demanding RF applications, combined with small
size and low coil power dissipation (see figure 1).
