MD-0709 feature:
PP plastic bobbin
High stability coils are space-wound.
Firm structure, can make adjustment from either top or bobbin end.
Frenquency range: 30MHZ-150MHZ.
Temperature coefficient: 150ppm/ºC (MAX).
Lead free products RoHS complaint.
Adjustable inductance value, alternate of a brass core will increase the usable frequency range of any specific coils form, but the inductance value will be decreased; if want to increase inductance value,ferrite magnetic core with low Q will be substitute.
When use of a Ferrite or Carbon core, the inductance minimum is measured with core 1/2 way out of top bobbin.
When use of an Aluminum or Brass core, the inductance maximum is measured with core 1/2 way out of top bobbin.
APPLICATION:
Widely used in: ANT, RF &OSC Coils. FM radio. TV receiver. Transceiver. Car, wireless telecommunication and RF electronic application.
