ELECTRICAL SPECIFICATIONS
Inductance: Measured at 1.0 V with no DC current
Incremental Current: The typical current at which the
inductance will be decreased by 5 % from its initial zero DC
value

circumference to within 0.250" [6.35 mm] of the insulating
sleeve edge
Operating Temperature: - 55 °C to + 125 °C (no load)
- 55 °C to + 85 °C (at full rated current)
Current Rating: Maximum continuous Operating current
(DC or RMS) based on a 40 °C temperature rise
