General Notes
•
•
•
•
•
All measurements are made at 60 Hz with resistive load at an ambi-
ent temperature of +25
°C
unless otherwise specified.
Operating temperature range (T
J
) is -40
°C
to +125
°C.
Storage temperature range (T
S
) is -40
°C
to +125
°C.
Lead solder temperature is a maximum of +230
°C
for 10 seconds
maximum;
≥1/16"
(1.59 mm) from case.
The case temperature (T
C
) is measured as shown on dimensional
outline drawings. See “Package Dimensions” section of this
catalog.
