Technical data sheet
Bin sort
The binning function allows component manufacturers to sort
components in up to ten bins. Sorting is carried out either by
absolute values or by percentage of values.
Component tests with up to 125 A DC bias
current
The 3255B and 3255BQ enable components to be measured
at up to 125 A when optional 3265B DC Bias Units are used.
Extended DC bias capability is also available with the 3255BL
which uses the 3265B/5A or 3265B/10A to extend the DC bias
current available to a maximum of 50A.
Up to five of the DC Bias Units can be used in parallel to
give a wide range of DC bias currents.
Internal DC bias is available as an option giving DC bias
currents from 1 mA to 1 A.
The 3265B has a number of safety and protection
features including a safety interlock system to protect
users against back EMFs. It is also fully protected
against over temperature, excess voltage drop and sense
lead failure.
3265B DC Bias Unit can deliver up to 25 A of DC bias current in steps of 0.025 A
SMD inductor tests up to 50 A
With 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
operational bias currents. The fixture operates with one or two
3265B/25A Wayne Kerr DC bias units and a 3255B
Inductance Analyzer. If two 3265B/25As are used then the
optional 5-328-2005 high current lead set will be required.
Four rear panel mounted BNC connectors and two captive
high current cables ensure simplicity and ease of use with a
3265B.
Interchangeable component test carriers ensure that the 1009
test fixture may be used with a wide variety of different
devices. Blank carriers are available which enable device
specific test fixtures to be developed or alternatively a carrier
design and manufacturing service is available.
Stable component fixturing ensures high accuracy and
repeatable measurements. Enclosed fixtures, with safety
interlocks, minimises risk to operators. 1009 DC Bias Fixture enables currents up to
50 A to be applied to an SMD inductor
