  • High temperature case with fixed, coplanar, "J" style terminals.
  • Operating temperature, -55°C to +125°C.
  • These are high efficiency toroidal chokes, 2 windings on one core. Can be used as single inductors or a 1:1 transformer. The coil windings can be connected in series or parallel depending on whether higher current or higher inductance is required. These also have a high efficiency core to minimize core loss and function at higher frequencies.
Electrical ratings are for Parallel connections unless labeled as "Series".
Note: All inductance values are in microHenries and all current ratings are in milliAmps.

*The current rating that will cause a maximum temperature rise of 40°C from a 85°C ambient.
**Saturation current is the DC current that will decrease the inductance approximately 30%.
