Characteristics

SMD Small Emitter Antenna for Automotive

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 +125ºC).
  • Wide working range (20kHz - 150KHz).
  • SMD mounting.
  • Custom inductance value under demand. 

  

The specification chart is a reference guide for the most common required values at working frequencies of 125 kHz, 20 kHz and 134.2 kHz. Any other inductance value at LF or tighter tolerances can be provided. Please contact our sales deparment for any inquiry.

This product has datasheet available upon request.
