| RMK 33N Vishay Thin Film Dual Value Chip Resistor, Center Tap FEATURES * High precision * Very low temperature coefficient * Excellent stability 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.
