Precision Resistor SR Series 1.0 Description The SR Series resistor networks are precision-class metal film components featuring tight resistance tolerance and low values of temperature coefficient of resistance (TCR). This resistor network package provides both excellent resistance ratio and TCR tracking with wrap around terminations. 2.0 Mechanical SR04 Series G 3.2 0.2 2.72 B 0.30 0.48 End View Side View 2.50 0.20 A 1 Side View H TopView 1.27 SR05 Series TopView 5.60 0.20 4.90 B A 0.6Max F E 8.89 (1.27 X 7) 1 10.16 0.20 D 2 C B 2 R9 R10 R6 F R11 R5 E R12 R4 D R13 R3 C R14 R2 B R15 R1 A A dimension mm R8 H R7 G 0.50 0.70 1 1.0 Max End View 3.0 Electrical 1 Maximum resistance (ohms): Resistance range (ohms): Absolute resistance tolerance (%): Absolute TCR (ppm/C) Resistance ratio tolerance (%) TCR tracking (ppm/C) (refer to note 1 & 2) Package power rating: Operating temperature: Storage temperature: 2 SR04 series: 10K SR05 series: 10K 10 - <20 20 - <100 100 - <5K 5K -max 0.05 (A) 0.02 (Q) 0.01 (T) 0.01 (T) 0.10 (B) 0.05 (A) 0.02 (Q) 0.02 (Q) 0.10 (B) 0.05 (A) 0.05 (A) 0.10 (B) 0.10 (B) 25 (E) 25 (E) 5 (M) 10 (Y) 10 (Y) 25 (E) 25 (E) 0.02 (Q) 0.05 (A) 5 (M) 2 (R) 1 (X) 2 (R) 5 (M) 2 (R) 5 (M) 5 (M) SR04 series: 0.1 watt @125C SR05 series: 0.7 watt @125C -40C to +175C -55C to +125C Note 1: Ratio values greater than 50:1 only available in 5 ppm/C TCR tracking tolerance Note 2: 1ppm/C TCR tracking only available for identical resistance values. 4.0 Part Number T Q ****/**** Y R A Resistance value Absolute TCR tolerance TCR tracking tolerance Packaging (1,000 on tape and reel) EG I S TERE D I S TERE D EG R 02 Product designator Form factor Absolute resistance tolerance Resistance ratio tolerance R SR ISO9001 ISO14001 A4 A8 303 561 Manufacturer(s) of the products described on this page are indicated by their respective logos. 22 2
