Rejustor Ensures Accurate Temperature Compensation

Essentially a re-adjustable resistor, the MBT-303-A rejustor is thought to be the first passive electronic temperature compensation (eTC) divider. The component particularly suits managing temperature in precise analog circuits, optical systems, sensors, and power supply compensation and calibration. The first member of a family, the MBT-303-A is a dual 30-kO divider where each resistor can be set to any value between 21 kO and 30 kO with an accuracy of 0.01%. It allows automated, independent adjustment of both resistance and the temperature coefficient of resistance (TCR). Another benefit, rejustors eliminate many of the detrimental side effects associated with digital compensation to achieve accurate and cost-effective temperature compensation. Available in a 16-lead QFN or 8-pin SOIC package, price for the MBT-303-A is $1.67 each/1,000. MICROBRIDGE TECHNOLOGIES INC., Burlington, MA. (888) 735-8786.
