Class B

Industry Standard Pinout

DC-DC Converter

0.5 Watt

The 0.5D8E_3U series is a family of cost effective 0.5W single output

DC-DC converters. These converters achieve low-cost and ultra-minia-

ture DIP8 pin size. Devices are encapsulated using flame retardant resin.

They are specially designed for applications where an isolated voltage is

required in a distributed power supply system. Such as: digit circuit con-

dition; normal low-frequency artificial circuit condition; relay drive cir-

cuit and data switching circuit condition, etc.

* Input filter components are required to help meet conducted emission class B,

which application refer to the EMI filter section.

** An external filter is required if the module hast to meet IEC61000-4-4 and

IEC61000-4-5.

Note:

1. Operation under minimum load will not damage the converter; However, they

may not meet all specification listed, and that will reduce the life of product.

2. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage

and rated output load unless otherwise specified.

3. Only typical models listed, other models may be different, please contact our

technical person for more details.

4. In this datasheet, all the test methods of indications are based on corporate

standards.
