The Wayne Kerr 3255B Benchtop Inductance Analyzer is able to accurately characterize devices in a clear and simple manner. The inductance analyzer has a frequency range of 20 Hz to 500 kHz.

At the design stage of component development, it is very important to analyze how components perform under different operating conditions. This includes operation over a range of frequencies, AC drive levels or DC bias currents.

The AC drive level can be set between 1 mV and 10 V. DC bias current can be set from 1 mA to 1 A internally (optional). Using the external 3265B range of DC Bias Units (sold separately), bias currents can be set to a maximum of 125 A.

Printed Output of Test Results

Using the parallel Centronics interface, the user can directly print all test results for further analysis and archiving.

In addition, via the optional GPIB interface, the instrument can be controlled from a PC and results can be read back for analysis and storage.

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 enables components to be measured at up to 125 A when optional 3265B DC Bias Units are used.

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 DC Bias Unit (sold separately) 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.

SMD Inductor Tests up to 50 A

With the addition of the 1009 DC Bias Fixture (sold separately), 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 (sold separately) and the 3255B Inductance Analyzer. If two 3265B/25As are used, then the optional 5-328-2005 high current lead set (sold separately) will be required.

Four rear panel mounted BNC connectors and two captive high current cables ensure simplicity and ease of use with a 3265B (sold separately).

Interchangeable component test carriers ensure that the 1009 test fixture (sold separately) may be used with a wide variety of different devices. Blank carriers are available to 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, minimizes risk to operators.
