DESCRIPTION
The PWR12xxC 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 PWR12xxC
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 –25°C to +85°C at no extra cost.
The PWR12xxC Series is ideal for use on high-density PC boards
where isolated, unregulated, power is needed. Standoffs allow for PC
board cleaning, helping preserve isolation. They also allow for visual
inspection of solder joints.

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 base metal is half hard brass. Lead
finish is matte tin 100 microinches minimum over nickel 40-80 microinches.
