QT8E_1U Series
0.25W - Single Output DC-DC Converter - Fixed Input - Isolated & Unregulated
DC-DC Converter
0.25 Watt
1000VDC isolation
Efficiency up to 72%
Operating temperature range:
-40°C ~ +85°C
SMD package
The QT8E_1U series is specially designed for applications where an isola-
Industry standard pinout
RoHS Compliance
ted voltage is required in a distributed power supply system.
High Power Density
External component required
These products apply to:
Small footprint
1) Where the voltage of the input power supply is fixed
(Voltage variation ≤ 10ꢀ)
2) Where isolation is necessary between input and output
(Isolation voltage ≤1000VDC)
3) Where the regulation of the output voltage and the output ripple
noise are not demanding.
Such as: pure digital circuits, low frequency analog circuits, and relay-
driven circuits.
