•
•
•
•
Tight TCR tracking down to 5 ppm/°C
Monolithic reliability
Low noise < - 35 dB
SMD precision networks
S08, S014, S016 cases
MSL 1 to JEDEC J-STD-020C specification
Actual Size
The RMKM series of small outline surface mount style
molded package can accommodate resistor network to your
particular application requirements in compact circuit
integration. The resistor element is a special nickel
chromium film formulation on oxidized silicon.
Utilizing those networks will enable you to take advantage of
parametric performances which will introduce in your
circuitry high thermal and load life stability (0.05 %
absolute, 0.02 % ratio, 2000 h at + 70 °C at Pn) together
with the added benefits of low noise and rapid rise time.
