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.

QD8E_1U Series
0.25W - Single Output DC-DC Converter - Fixed Input - Isolated & Unregulated
Typical characteristics
Test configurations
Input reflected ripple current test step
Input reflected ripple current is measured through a source
inductor Lin (12µH) and a source capacitor Cin (47µF, ESR<1.0Ω
at 100KHz) at nominal input and full load.
Output ripple & noise measurement test
The scope measuremnet bandwidth is 20MHz.
EMI filter
Input filter components (C1, L, C2, C3) are used to help meet
conducted emissions requirement for the module. These
components should be mounted as close as possible to the
module; and all leads should be minimized to decrease
radiated noise.
