| VTF (Custom) Vishay Thin Film Conformal, Single In-Line Resistor Networks (Custom) FEATURES * Lead (Pb)-free available * Minimal PC board space * Standard 100 mil centers * Exceptional stability over time and temperature (500 ppm at + 70 C at 2000 hours) * Integrated construction Wirewound or metal film performance in a space saving package. SIP networks available in 3 - 10 pin sizes can obtain important performance parameters in an economical, mass producible style. SIPs take up the least amount of board space and are the easiest possible configuration to hand-insert into printed circuit boards. Standard pin centers are 0.100". Passivation coatings plus a conformal coating of epoxy protect the active element from the outside environment. * Conformal coating flame resistant (UL94V-0 rating) Pb-free Available RoHS* COMPLIANT TYPICAL PERFORMANCE ABS TCR 10 ABS TOL 0.05 TRACKING 2 RATIO 0.02 SCHEMATIC THROUGH HOLE NETWORKS Custom schematics available.
