Trimmable chip resistors in thick film technology (without pre-trimm)
CRA: Contact areas Nickel-barrier / matte-tinned
glass-passivized, for soldering
CRB: Contact areas PtAg – non-magnetic
un-passivized, for soldering and conductive gluing
Suitable for Laser and air-abrasive trimming
High trimming ratios by special geometries
High temperature application possible (up to 300° CRB only)
C;
Suitable for high vacuum applications – no organics
