HIGH-MEG OHM RESISTORS
ZERO OHM & JUMPER WIRE
HIGH-MEG OHM RESISTOR
INTRODUCTION
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.
HMG resistors are particularly suited for voltage
dividers, X-ray equipment, and high voltage power
supplies.
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.
