PRECISION RESISTORS

High precision, thin film resistors manufactured with a NiCr alloy spattered onto an alumina substrate. TP resistorshave linear operating temperatures from -55C to +125C. Standard TCRs include 2ppm/C and 5ppm/C. These modelsalso exhibit excellent long-term stability, low current noise, a low voltage coefficient and a low thermal EMF. Typicalapplications are: Discrete voltage dividers, analogue circuits in industrial measuring equipment, control, medicalelectronics, ATE, aerospace, and reliable power electronics.GENERAL SPECIFICATIONSModel ResistanceNote1 TCR [ppm/ ]Note1 Tolerance Standard Resistance Power [W]Note2 Working Voltage[V] TP48 TP47 TP46 TP45 100-20K +-1(X) 0.1(B) E96, E24(includes 2.5 and 5.0) Note3 0.25 Root(PR) 100-150K +-2(Y) 0.02(Q) +-5(Z) 0.05(A) TP48,TP47 50-150K +-10(N) 0.1(B) TP46,TP45 50-510K TP48,TP47 10-150K +-25(E) 0.1(B) TP46,TP45 10-820K Note1: -55C 125CNote2: -55C 70CNote3: Please enquire if resistance values are not E96 or E24CHARACTERISTICS Values in [ ] mean change in ohmic value after testStorage Temp.
