Knowles Precision Devices Non-Magnetic Variable Inductors

Description
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. Characteristics Patent pending, precision machined design 7nm high in SMD, Vertical SMD and thru-hole versions Nominal values of 32 to 118nHm 2 to 7 turns Q as high at 121 @ 100MHz, SRF 0.7-1.5GHz Superb shock, vibration and thermal tolerance -40 degrees C to +85 degrees C Customized version requests welcomed
