Vishay Dale
Power Metal Strip® Resistors, High Power (5 W)
Low Value (down to 0.001 ï), Surface Mount
FEATURES
⢠Improved thermal management incorporated
into design
⢠Ideal for all types of current sensing, voltage
division and pulse applications including
switching and linear power supplies,
instruments, power amplifier
⢠Proprietary processing technique produces
extremely low resistance values
⢠All welded construction
⢠Very low inductance (< 5 nH)
⢠Solid metal nickel-chrome or manganese-copper alloy
resistive element with low TCR (< 20 ppm/°C)
⢠Excellent frequency response to 50 MHz
⢠Low thermal EMF (< 3 μV/°C)
⢠AEC-Q200 qualified (1)
⢠Compliant to RoHS Directive 2002/95/EC
Note
(1) Flame retardance test may not be applicable to some resistor
technologies.
