INTRON precision thin film SIL voltage divider are made by vacuum depositing a controlled film of NiCr on high purity alumina substrate. The resistors are formed using high resolution photolithography. The conducting traces are formed by deposited copper. The values are micro trimmed to the exact value with built in absolute and ratio tolerances. The TCR and tolerance is obtained by process capability and does not rely on a selection process. Any custom design resistor network within the manufacturing capability can be supplied.
