These devices are intended for wave soldering or manual soldering.
they are not intended to be subject to surface mount processes under any circumstances.
The normal wave soldering process can be used with these devices where the device is subjected
to a maximum wave temperature of 260°C for a period of no more than 10 seconds. Within this
time and temperature range, the integrity of the device’s plastic body will not be compromised and
internal temperatures within the converter will not exceed 175°C. Care should be taken to control
manual soldering limits identical to that of wave soldering.

NOTES:
. When operated within the SAFE OPERATING AREA as defined
by the above curves, the output voltage of Hpr0xxC devices is
guaranteed to be within 95% of its steady-state value within 00
milliseconds after the input voltage has reached 95% of its steady-
state value.
2. For dual output models, total load capacitance is the sum of the
capacitances on the plus and minus outputs.
