One design concept allows an engineer to choose from three the styles new (Lo Ohm, Power, or Ultra Precision) while staying within standard circuit board land pattern guidelines now accepted by the wirewound resistor industry. Each size offers low profile case design with flexible tinned copper terminations for reliable solder Characteristics Electrical Solder Immersion: Load Life: Moisture Resistance: Thermal Shock: Dielectric Withstand: Short Term Overload: Solderability: Flammability: 260C for 10 seconds. 2000 hours at rated power at 25C. 240 hours with humidity ranging from 80% RH to 98% RH. -55C for 15 minutes no load. 1000 Volts. 5 times rated power for 5 seconds 95% coverage within 1/16" of contact point. UL94V Rating. Typical R 0.1% 0.2% 0.1% 0.1% 0.1% ------- joints. All styles utilise a fully welded construction technique, unlike other designs that rely solely on tinned termination connections. These features allow the S Series to withstand the higher temperatures (IR) associated with reflow, vapour phase, or infrared manufacturing processes without degradation.
