(A)
(1) All test data are referenced to 25°C ambient temperature
(2) Continuous operating temperature range must be within -40°C/+150°C (ambient + self heating) under worst case
conditions ; exposure to 180°C peak is allowed according to IEC85 H thermal index for all raw materials used
Circuit design, component placement, PCB tracks size and thickness, airflow and other cooling provisions all affect the part
temperature rise
It is suggested that the component be tested at the system level to verify its temperature after 30 minutes in the end application
(3) +/-5% MAX on -40°C/+150°C temperature range
(4) DC current that will cause an approximate ∆T of +50°C
(5) DC current that will cause L0 to drop approximately 30%

Soldering
Reflow or vapor-phase soldering
processes are compatible to mount
components from the UC series
A maximum soldering temperature of
260°C during 10s shall not be exceeded
The reflow condition recommended
beside is according to the equipment
used at PREMO
Differences could appear as a result of
the type of machine, reflow conditions,
method…
