SEA
SMD Small Emitter Antenna
Characteristics
This part can be used as emitter antenna of a RF application in low frequency range and
can be mounted like any other SMD component, directly to the PCB. Some use example:
telemetric, telecontrol, atomic watch, PKE, etc.
Size of this component compared to other existing emitter antennas is very small.
- Small size (50.8 x 10.6 x 6.8).
- High stability in temperature (-40ºC up to +85ºC).
- Wide working range (20kHz - 150KHz).
- SMD mounting.
- Custom inductance value under demand.
50.80x10.60x6.80mm (33 uH - 470 uH)
