0.5S4E_3U Series
0.5W - Single Output DC-DC Converter - Fixed Input - Isolated & Unregulated
DC-DC Converter
0.5 Watt
4 Pin SIL
Efficiency up to 83%
EMI complies with EN55032
Class B
The 0.5S4E_3U series is a family of cost effective 0.5W single output
DC-DC converters. These converters achieve low-cost and ultra-minia-
ture SIP4 pin size. Devices are encapsulated using flame retardant resin.
3KVDC Isolation
Operation temperature range:
-40°C ~ +85°C
Industry Standard Pinout
Low ripple and noise
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.
* Measured with a simulated source inductance of 12µH and a source capacitor
Cin (47µF, ESR<1.0Ω at 100KHz).

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.
