variable moulded inductors - May 2012

Available from TFC, the MD series enhanced range of variable molded inductors, used in FM radio, satellite receiver, car navigation system, CATV and cable TV applications, with a choice of core materials; carbonyl, aluminium, brass and ferrites, offering high temperature stability. 

These variable molded inductors can be supplied shielded or unshielded.

These variable molded inductors offer a very wide inductance range and multiple choice of model size and frequency of operation.

  • Inductance ranges from 0.01uH ~ 1.5uH
  • Frequency raging from 10MHz~ 500MHz
  • Operating temperature: -40°C to +85°C
  • Width 4.5mm to 12.7mmHeight 5mm to 18.8mm 
When using ferrite or carbonyl cores, the minimum inductance is measured with the core in a mid position within the bobbin. When using aluminium or brass cores, the inductance max. is measured with core half way out of the bobbin.
