With an overall height of only 0.350", these variable inductors are ideal for applications where low-profile circuit boards & high Q values are essential. The coils and PTFE cores are made to precision to guarantee a constant winding pitch and consistent relationship to the printed circuit board. Tuning is done by means of threaded PTFE and Non-Magnetic Copper Alloy core. JMC can provide custom variable or fixed inductors for any applications upon request. All Johanson Variable Inductors are RoHs compliant.
