The PZFR series is a new generation of precision resistors based on Z1 foil resistor technology. This resistor is virtually insensitive to some of the factors that cause resistance instability. The foil material is pasted to a ceramic substrate by special bonding material. Although foil and ceramic material have different coefficience of thermal expansion, the bonding material balance and compensate for changes in resistance due to temperature changes, leading to ultra low TCR . The laser trimming adjustment current path to achieve tight tolerance. This series of resistors is produced by C&B Precision Centre and is available in short lead time, with no minimum order quantity.
