HIGH-MEG OHM RESISTORS ZERO OHM & JUMPER WIRE

ZR25R-0R0-W 数据手册

  
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%  
The HMG resistors are suited for high voltage and  
high impedance applications where resistance and  
stability are required.  
•Standard TCR ±350 ppm (200 ppm available)  
•Standard resistance to 100 meg ohm.  
Consistent Quality and reliability is achieved by thick  
film construction on high-grade ceramic core.  
Multilayer epoxy coating offers exceptional  
protection.
