Microbridge Technologies Type I and Type II: Rejustors suit extreme-temperature environments

Suiting applications requiring precision and accuracy in extreme-temperature environments, the Type I and Type II rejustors operate over a –55 to +230°C extended-temperature range and claim a lifetime drift of less than 1%. The resistor element allows independent electrical adjustments to any value from the device’s nominal to 80% of the nominal value. The Type I rejustor consist of a pair of nominally 27-kΩ rejustors, offering adjustments of less than 0.1% and maintaining a ±2.5% tolerance over the operating temperature. The Type II rejustors feature ±0.7% resistance tolerances and are tuned to a 50°C window or band within the temperature range. The HT-rejustor dividers provide temperature stability, allowing a ±1% ratio between the two resistors, regardless of the adjustment state of either HT rejustor if both devices are at the same temperature. The Type I, Type IIA, and Type IIB rejustors cost $6.95, $7.64, and $8.34 (1000), respectively.
