Dual Value Chip Resistors, 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 < 10 ppm/°C
• Excellent stability 0.03 % (2000 h, rated power,
at + 70 °C)
• Wirebondable
