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.
