Adjustable resistor tunes TCR passively

摘要

An addition to the Rejustor line of adjustable resistors, the MBT-303-A is billed as the first passive electronic compensation (eTC) divider, enabling—for the first time—continuous high-precision adjustment for both resistance and temperature coefficient of resistance (TCR). The device can increase TCR accuracy by more than 10 times;rnreplaces other solutions such as digital potentiometers, thin-and thick-film laser trimming, digital conditioning, and ze-ner zapping; and is suitable for managing temperature in precise analog circuits, optical systems, sensors, and power supplies in a variety of applications.
