*1 Allowable DC Current: DC Current value when coil temperature
rise is within
∆T=
35°C or when inductance change ratio is within
∆L/L=
−30%, whichever is lower.
For complete environmental specifications, please refer to www.koaspeer.com
Operating Temperature Range: −40°C – +120°C
The operating temperature range of the coil (ambient temperature + self heating)
must remain at +120°C or less
