Adjustable coils from TFC, this is not a wind up! - November 2013

Total Frequency Control has a wide range of adjustable coils, which are used in FM radio, satellite receiver, car navigation systems, cable TV and CATV applications. Also ideal for use in oscillator circuits, TFC’s adjustable coils can be custom wound and manufactured with short lead times to meet sample and production requirements and have competitive pricing for volume applications.

These inductors offer a very wide inductance range and multiple choice of model size and frequency of operation and can be used for generic replacements. Choices of either Standard or Custom Wound, tuneable shielded or unshielded. The products provide a high Q component with good resistance to shock and vibration with moulded variants and a range of core materials including carbonyl, ferrite, aluminium and brass. 

Adjustable coil windings may be close wound or space wound and the enclosures of leaded or smd variants. When using ferrite or carbonyl cores, minimum inductance is measured with the core in a mid-position within the bobbin. When using aluminium or brass cores, the maximum inductance is measured with the core half way out of the bobbin.
