Wirebondable High Precision Single Value
Thin Film Chip Resistors
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.
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.
Precision wafer laser trimming is employed to trim each
resistor to precise tolerance.
FEATURES
• Precise tolerance from ± 0.01 % to ± 1 %
• Wide resistance ranges from 1 k to 2 M
• Low temperature coefficient ± 10 ppm/°C max.
• Aluminum or gold pads
• Excellent stability < 500 ppm (2000 h, at + 70 °C
under Pn)
• Wirebondable
• For high temperature see datasheet RMKHT:
