WIREWOUND RESISTOR
AS
SERIES
1/4 watt to 10 watts
±5%, ±3%, ±1%, ±.5% tolerance
0.1 ohm to 175K ohms
Resistance wire TCR ±20 ppm/°C
SPECIFICATIONS:
Inductance of AS-1/2 is less than 1μH at 1MHz. * Typical inductance of AS-1C <5 ohms is < 1μH.
To order non-inductive types, add the prefix "N". Example: NAS-1, NAS-2C, etc. Lower values available upon request.
