B-H Analyzer - DC-bias test system

Automatic test on power inductor properties with DC biasing

DC-bias test system (SY-960, SY-961, SY-962）

SMD Power inductor	Toroidal coil inductor

DC bias current: 30A, max
AC Ripple current: ±6A, max
Test frequency (Sinusoidal): 10kHz to 3MHz
Test frequency (Pulse): 10kHz to 1MHz (Duty10%-90%)

Pulse (Triangular signal waveform in current at specimen, called QUASI-CHOPPER), or Sinusoidal test with DC biasing

Test example on chip inductor (Chopper excitation)

	Hint: In actual operation, both AC magnetic field and DC magnetic field may be applied at the same time usually. Magnetic property test with changing DC biasing level is considered important.

		ferrite L=1.0μH


		Fe-Based amorphous L=311μH


		iron powder L=8.4μH

DC-bias test system is uniquely used as an option for SY-8218 or SY-8219 and not be used with other equipment. Adjustment and inspection as a system with BH analyzer is requited.
BH analyzers(SY-8218/SY-8219) at the customer end will be returned to our factory for adjustment and inspection when DC-bias test system can be configured as a system.
