HIGH-MEG OHM RESISTORS ZERO OHM & JUMPER WIRE HIGH-MEG OHM RESISTOR INTRODUCTION FEATURES •Low cost, High stability, accuracy, and reliability •Standard tolerances: ±2% & ±5% •Standard TCR ±350 ppm (200 ppm available) •Standard resistance to 100 meg ohm. The HMG resistors are suited for high voltage and high impedance applications where resistance and stability are required. Consistent Quality and reliability is achieved by thick film construction on high-grade ceramic core. Multilayer epoxy coating offers exceptional protection. DERATING CURVE 70° 100 Rated Load (%) 80 HMG resistors are particularly suited for voltage dividers, X-ray equipment, and high voltage power supplies. 60 40 20 150° 0 SPECIFICATIONS 40 60 80 100 125 140 160 180 200 Ambient Temperature (°C) PART NUMBER EXAMPLE HMG 100 R - 33M - J PERFORMANCE(MAXDR) Type L Dimension (mm) D H HMG25 6.5±0.5 HMG50 9.5±0.5 HMG100 12.0±1.0 HMG200 16.0±1.0 2.3±0.3 3.2±0.3 4.5±0.5 5.0±0.5 d±.05 20 20 26 26 0.60 0.60 0.80 0.80 Power Maximum Maximum Rating Working Overload Voltage Voltage 1/4W 250 500 1/2W 500 1000 1W 750 1500 2W 1000 2000 Resistance Range ±2%(G) ±5%(J) 11M-22M 11M-22M 11M-100M 11M-100M 11M-100M 11M-100M 11M-100M 11M-100M Temperature Cycling Load Life 1000 Hours Shelf Life at 25°C Effect of Soldering Moisture Resistance Short-Time Overload ±0.5% ±2.0% ±1.0%(12 months) ±1.0% ±2.0% ±1.0% ZERO OHM & JUMPER WIRE SPECIFICATIONS (sizes in mm) Construction Jumper Wire Ceramic Ceramic Part Number ZR25*-0R0-W ZR25*-0R0-C ZR12*-0R0-C L 61.5±1 6.5±.3 3.8±.5 D H 2.5±.2 1.5±.2 20 20 d 0.6±0.05 0.6±0.05 0.45±0.05 ZR25-0R0-C / ZR12-0R0-C C * “R” for Tape & Reel, “A” for Tape & Ammo, “B” for Bulk Pack.
