Rejustor-Based Products
The Rejustor, from Microbridge, is an electrically adjustable resistor that can be precisely adjusted, in-circuit, to calibrate and compensate analog circuits and systems. Low-TCR Rejustors are resistance-only adjustable, available in standard and low-power duals and low-power singles. eTC Rejustors provide passive temperature compensation in addition to resistive calibration (the only passive, adjustable TCR resistor on the market). High-Temperature Rejustors provide stable operation from -55C up to +230C. Active CMOS Rejustor Amplifier Products integrate Rejustors with linear CMOS amplifier elements, to provide a verstaile range of stable linear amplification and temperature compensation solutions.
Low TCR Rejustors
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.
- Resistance-adjustment
- Adjustment range: 30% down from as-manufactured resistance
- Bidirectional adjustment within active range
- Adjustment resolution to 0.1%, or better
- Precision Temperature coefficient as resistor is adjusted
- TCR: 0±100ppm/K
- Two electrically isolated Rejustors per package
