MEDER electronic
HF Series
High Frequency and
High Power Reed Relays
DESCRIPTION
High voltage RF Reed Relays use a patented coil
encapsulation, external electrostatic shields, and
magnetic shields. For this series we use a special
copper-plated Form A switch with a breakdown
voltage up to 10 kVDC. The contacts are suitable
for carrying current up to 3 Amps (5 Amps available)
at 30MHz.
FEATURES
•
Normally open contacts (Normally closed
contacts are available)
•
5 Amps available
APPLICATIONS
•
Radio frequency technology
•
Antenna tuning units
•
Transmit / receive requirements
DIMENSIONS
All dimensions in mm [inches]

* The pull-in / drop-out voltage and coil resistance will change at rate of 0.4% per °C.
** Re-closure of Form B may occur if the max. coil voltage is exceeded. Coil polarity on Form B must be observed. Pin five
is positive.
