RMK 33N
Vishay Thin Film
Dual Value Chip Resistor, Center Tap
Actual Size
The demand for high precision, high stability microchips for
both military and industrial environments is increasing with
the growth and sophistication of modern day hybrid circuitry.
The need for high accuracy ultra stable micro dividers
particularly triggered the development of these third generation
nickel chromium microchip dividers which offer standards of
accuracy and thermal/time stability never achieved before in
the conventional second generation thin metal film
technologies.
FEATURES
• High precision
• Very low temperature coefficient
