1S4E_S1U series
1W - Single Output - Fixed Input - Isolated & Unregulated
MINIATURE SIP PACKAGE
DC-DC Converter
1 Watt
The 1S4E_S1U series are specially designed for applications where a single power
supply is isolated from the input power supply in a distributed power supply
system on a circuit board.
Efficiency up to 83%
Small Footprint
Industry standard pinout
UL94-V0 package
RoHS compliance
EMI complies with
EN55022 Class B
Miniature SIP package
Single output voltage
1kVDC Isolation
These products apply to:
1) Where the voltage of the input power supply is fixed
(voltage variation ≤ 10ꢀ)ꢁ
Temperature Range:
-40°C~+85°C
Low ripple and noise
2) Where isolation is necessary between input and output
(isolation voltage = 1500VDC)
3) Where the regulation of the output voltage and the output ripple and noise
are not demanding.
Such as: purely digital circuits, ordinary low frequency analog circuits and IGBT
power device driven circuits, etc.

Input filter components are required to help meet conducted emissions Class B,
which application refer to the EMI filter of design & feature configuration.
** An external filter capacitor is required if the module has to meet IEC 61000-4-4
and IEC 61000-4-5.

Isolation specifications
1. All specifications measured at TA = 25°C, humidity < 75ꢀ, nominal input voltage
and rated output load unless otherwise specified.
2. Exceeding the absolute ratings of the unit could cause damage. It is not allo-
wed for continuous operating.
3. Operation under no-oad conditions will not mdamage these devices, however
they may not meet all listed specifications.
