Performance Data
Physical Data
Thin film resistor material, overglaze and organic protection
are screen printed on a 96% alumina substrate. Wrap-
around terminations have an electroplated nickel barrier
and tin-lead solder coating, this ensures excellent ‘leach’
resistance properties and solderability. Chips can withstand
immersion in solder at 260°C for 30 seconds.
