Precision Thin Film
INTRON precision resistor are made by vacuum depositing a controlled film of NiCr on high purity alumina substrate. The resistors are formed using high resolution photolithography. The values are micro trimmed to the exact value with a tolerance of 0.05%. The TCR and tolerance is obtained by process capability and does not rely on a selection process. Precision Resistor sets matched to precise tolerance and TCR can be given.
Intron is high quality manufacturer of precision resistors and foil resistors distributer.
