aInductance of AS-1/2 is less than 1µH at 1MHz.
To order non-inductive types, add the prefix "N". Example: NAS-1, NAS-2C, etc.

* Typical inductance of AS-1C <5 ohms is < 1µH.
Lower values available upon request.
NOTE:
• Coating and marking is resistant to normal freon degreasing.
Consult factory for special requirements.
• AS marking available in Alpha Numeric or Colorbanding -
identification available.
