Topic:Kt Kingtronics Tells You Trimming Potentiometers Materials and Construction
Content:
The combination of proprietary cermet element technology, precious metal brush contacts and swaged pin element connections used in BI trimmers permits the manufacture of precision, high quality trimmers that span the resistance range from 10 ohms to over 5 megohms. The small size and planar construction of these trimmers minimize stray circuit reactances and permit the trimmers to perform well in many high frequency applications.LeadscrewPrecision brass leadscrew cuts its own grooves in the teflon rotor so that the operation of the rotor is free of backlash. Setability is excellent.Sealing GroovesLeadscrew has specially cut grooves to ensure a watertight seal.Ceramic SubstrateHigh density substrate provides an excellent base for the element and is a good conductor of heat.Cermet ElementBI’s proprietary cermet element matches the materials in the wirebrush so that CRV is minimized and the high temperature setability is excellent.Swaged PinsBI’s pin connections, which are swa
