up to 125 a dc bias current in steps of 25 madc bias fixture model 1009 allows accurate and safe testing of smd inductorsadds additional functionality
component tests up to 125 a dc bias currentto evaluate components at high currents the 3265b/25a dc bias units may be used with either the wayne kerr 3255b inductance analyzer or the 3260b precision magnetics analyzer. bias current may beset from 25ma to 25a in steps of 25ma. these units may not be used with a 3255bl.
additional dc bias units can be added in parallel such that with five units connected in parallel it is possible to set bias currents up to a maximum of 125 a dc. for extended frequency, up to 3mhz, 50a is available when two 3265bqs are used.
5a, 10a and 20a models are available which may be connected in parallel to give up to five times the maximum rated dc bias current. 
the instruments have a number of safety and protection features including a safety interlock system to protect the user against back emfs. it is also fully protected against over temperature,excess voltage drop and sense lead failure.
3265b/25a dc bias unit can deliver up to 25 a of dc bias current in steps of 25ma
smd inductor tests up to 50 awith the addition of the 1009 dc bias fixture dc bias currents up to 50 a can be applied to an smd inductor during component test in order to evaluate the devices thoroughly at the operationalbias currents.
the fixture operates with either one or two 3265b wayne kerr dc bias units and a 3260b precision magnetics analyzer. the optional 1009 50a lead set, 5-328-2005, will be required if two 3265b/25asare used.
four rear panel mounted bnc connectors and two captive high current cables ensure simplicity and ease of use with the 3265b.
interchangeable component test carriers ensure that the 1009 dc bias fixture may be used with a wide variety of devices. if a device package is not supported by one of the standard carriers then acustom carrier design service is available.
1009 dc bias fixture enables currents up to 50 a to be applied to an smd inductor
stable component fixturing ensures high accuracy and repeatable measurements. enclosed fixtures, with safety interlocks, minimises risk to operators.
