Vishay Sfernice
Wirebondable High Precision Single Value
Thin Film Chip Resistors
FEATURES
• Precise tolerance from ± 0.01 % to ± 1 %
• Wide resistance ranges from 1 k to 2 M
Actual Size
The demand for high precision, high stability resistive chips
for incorporating in hybrid micro-circuits has increased and
is catered for by the comprehensive range of VISHAY micro
and minichips.
• Low temperature coefficient ± 10 ppm/°C max.
The super stable RMK nickel chromium resistive film has
transformed the performances and characteristics of micro
resistive chips bringing a “new state-of-the-art” to the
technology. A variety of substrates are available in silicon,
alumina, to ensure the best possible characteristics
compatible with your application needs.
• Wirebondable
• Aluminum or gold pads
• Excellent stability < 500 ppm (2000 h, at + 70 °C
under Pn)
• For high temperature see datasheet RMKHT:
www.vishay.com/doc?60075
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
Precision wafer laser trimming is employed to trim each
resistor to precise tolerance.
