0.5T8E_1U Series
0.5W - Single Output DC-DC Converter - Fixed Input - Isolated & Unregulated
DC-DC Converter
0.5 Watt
The 0.5T8E_1U series is specially designed for applications where a group of polar
power supplies are isolated from the input power supply in a distributed power
supply system on a circuit board.
Small footprint
Industry standard pinout
Low temperature rise
Internal SMD construction
No external component
required
Miniature SMD package style
High efficiency up to 78%
1000VDC isolation
Temperature range:
-40°C ~ +85°C
These products apply to:
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)
RoHS compliance
3) Where the regulation of the output voltage and the output ripple noise are not
demanding
Such as: digit circuit condition; normal low-frequency artificial circuit condition;
relay drive circuit condition, etc.
