- Maximum DC bias
- ： 30A
- Maximum ripple
- ： ±6A
- Measurement frequency (sine wave)
- ： 10kHz～3MHz
- Measurement frequency (square wave)
- ： 10kHz～1MHz (Duty10%～90%)
SMD power inductor
Toroidal coil
Square wave (triangular current flowing through the sample = pseudo chopper), superimpose DC on the sine wave to measure magnetic characteristics
Measurement example of chip inductor (chopper excitation)
In real circuits, DC and AC magnetic fields are often applied to magnetic parts, and it is important to measure the magnetic properties that change due to DC bias.

* The DC bias tester is an option only for SY-8218 and SY-8219, so it cannot be used with other equipment.
* It needs to be adjusted with the B-H analyzer main unit at the time of shipment.
* If you already have the main unit (SY-8218/8219), you will need to take it back to our factory for adjustment.
