SMD Precision Current Sense Resistor Type S Series Type S Series Characteristics Electrical Tyco introduces a range of surface mount power resistors to meet today's circuit design needs. One design concept allows an engineer to choose from three styles (Lo Ohm, Power, or Ultra Precision) while staying within the new standard circuit board land pattern "SL" Lo Ohm R01 - R05 R005 - R075 R005 - R099 R005 - R099 E24 1%, 3%, 5%. 0.5 Watt 1 Watt 2 Watts 3 Watts See Curve Below Power x Resistance Power x Resistance Power x Resistance Power x Resistance < 7 Nanohenries Values S1/2: Values S1: Values S2: Values S3: Grid: Resistance Tolerances: Power Rating @ 25C S1/2: Power Rating @ 25C S1: Power Rating @ 25C S2: Power Rating @ 25C S3: Derating: Max.

Each size offers low profile case design with flexible tinned terminations for copper reliable solder 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 associated with reflow, vapour phase, or infrared (IR) Characteristics Electrical manufacturing 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.
