FEATURES
Ideal for all types of current sensing, voltage
division and pulse applications including
switching and linear power supplies, instruments,
power amplifiers
Proprietary processing technique produces
extremely low resistance values
All welded construction
Solid metal Nickel-chrome or Manganese-
copper alloy resistive element with lowTCR
(< 20 ppm/C)
Solderable terminations
Very low inductance 0.5nH to 5nH
Excellent frequency response
Low thermal EMF
Lead (Pb)-Free version is RoHs Compliant
*For values above 0.1
derate linearly to 80% rated power at 0.5
Part Marking: DALE, Value, Tolerance: due to resistor size limitations some resistors will be marked with only the resistance value.
