RS92N, RS92Na, and an resistors are the modern generation of precision resistors. the standard design of these resistors prov ides a unique combination of characteristics found in no other single resistor. our application engineering department is available to advise and to make recommendations. for non-standard technical requirements and special applications, please contact us. features ? temperature coefficien t of resistance (tcr): 2 ppm/c typical (- 55 c to + 155 c, ref. + 20 c) ? resistance range: 80.6 to 120 k ? vishay foil resistors are not restricted to standard values; specific ?as required? values can be supplied at no extra cost or delivery (e.g. 1k2345 vs. 1k) ? rated power: to 0.25 w at + 125 c ? tolerance: 0.01 % ? load life stability: to 0.005 % at 70 c, 2000 h at rated power ? electrostatic discharge up to 25 000 v ? non inductive, non capacitive design ? rise time: 1 ns effectively no ringing ? current noise: < - 40 db ? thermal emf: 0.05 v/c typical ? voltage coefficient: < 0.1 ppm/v ? low inductance: < 0.08 h typical ? non hot spot design ? terminal finish available: tin/lead alloy ? matched sets are available per request (tcr tracking: to 0.5 ppm/c) ? for better tcr and pcr performances please review the rnc90z and z555 datasheets table 1 - tolerance and tcr vs. resistance value (- 55 c to + 155 c, + 20 c ref.) resistance value ( ) tolerance (%) typical tcr and max. spread (ppm/c) 80.6 to 120k 0.01 2 3 table 2 - mechanical and environmental specifications mechanical protection insulated case resistive element nickel-chromium unit weight 0.3 g temperature limits - 55 c to + 155 c climatic category 55/155/56
