PWR12XX
DESCRIPTION
The PWR12XX Series offers a broad line of low-cost, high-
performance, unregulated, single and dual output DC/DC
converters in a 24-pin DIP package. These miniature
converters offer better performance and lower cost in
industry-standard packages and pinouts. The PWR12XX
Series is internally filtered. No external parts are necessary.
Surface mounted components and a low thermal resistance
encapsulant allow for superior reliability, excellent thermal
dissipation, and an extended temperature range of 鈥?5擄C
to +85擄C at no extra cost.

MATERIAL: Units are encapsulated in a low thermal resistance
molding compound which has excellent chemical resistance, wide
operating temperature range, and good electrical properties under
high humidity environments. The encapsulant and outer shell of the
unit have UL94V-0 ratings. Lead material is brass with a solder plated
surface to allow ease of solderability.
