B-H Analyzer - DC-bias test system

Automatic test on power inductor properties with DC biasing
		SMD Power inductorToroidal 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.
