The Rejustor™ Company

 

Low-TCR Rejustors (Rejustor Standard Products)

Microbridge manufactures Low-TCR Rejustors as standard products. These devices offer resistance-only adjustment with stable TCR across the adjustable range. Available in QFN or SOIC packages for PCB mounting, these devices are used to adjust sensors, amplifiers, regulators, optical components and in a variety of other applications. Low TCR Rejustors are available in tape and reel, or in tubes for sample quantities.

eTC Rejustors

The eTC Rejustor provides the next-generation solution for passive calibration and temperature compensation. eTC Rejustors are passive resistive devices with adjustable resistance and TCR (temperature coefficient of resistance). These devices are used not only to correct for variation in offset, but also for variation in temperature sensitivity and drift. eTC Rejustors are typically used in circuit applications where high precision and temperature stability is required and the exact value of the desired resistance and temperature correction factor depends on variation in other circuit components – for example, batch-to-batch or unit-to-unit manufacturing variations, or where packaging-induced stresses cause significant changes in electrical output.

The ohmic value and TCR (Temperature Coefficient of Resistance) of an eTC Rejustor can be adjusted independently. Both resistance and TCR can be adjusted many times using analog signals. Once adjusted these parameters hold their final value indefinitely, unless they are re-adjusted.
