The Chro m a 19301A i m p u l s e W i n d i n g
Tester combines high & low inductance test
technologies, has a maximum impulse voltage
of 1000V, and a high speed sampling rate
of 200MHz which satisfies most of the test
requirements for power inductor products
with a wide inductance range from 0.1uH to
100uH. The built-in functions of Area Size

ΔRESONANT AREA functions are able to
inspect coils for poor insulation effectively.
The inspection of wound components for
production includes the electrical character-
istics test and the withstand voltage test of
the electrical safety standard. Poor insulation
of a coil, which is a common issue that causes
layer short and/or short circuit with the output
pin during use, can be caused by bad design,
bad molding process, or deterioration of the
insulation material. Therefore, it is necessary
to perform the layer short test on any winding
component or coil.
The 19301A, which is specifically designed
for wound component tests, utilizes a high
voltage & low capacitance capacitor (low test
energy) in parallel with a coil to form an RLC
resonant, which is called damping. Analyzing
the decay of the waveform via an analysis
technology with high speed, precise, and
accurate sampling can successfully detect
poor insulation within a coil. It provides the
winding quality test and the withstand voltage
test on the cores for power inductors, and
also makes the manufacturer and user checks
of the quality of winding component products
more efficient.
T h e 19301A c an be use d t o t e s t l o w
inductance winding components with a
minimum inductance down to 0.1uH. It
provides 4-terminal (4-wire) measurement,
contact checks, inductance check and voltage
compensation for testing low inductance
winding components in order to avoid
gross inaccuracies in test voltage caused by
the inductance variation of the DUT or the
equivalent inductance of wires, which makes it
the best impulse winding test instrument for
low inductance winding components.
The 19301A has an extremely high test speed
that can reduce testing times and increase
productivity in automated production. In
addition, the voltage compensation function
re d u ces th e i m pact of t h e equiv a l e n t
inductance of the wiring in automated
machines.
The brand new Human Machine Interface has
a colorful display and screen capture function.
The screenshot of the waveform, which is not
only suitable for the on-site production but
also applicable for R&D and Quality Assurance
to analyze and c ompare, can be saved
through the USB port on the front side of the
instrument. This improves the convenience of
operation.
