QD8E_3U Series

0.25W - Single Output DC-DC Converter - Fixed Input - Isolated & Unregulated

DC-DC Converter

0.25 Watt

8 Pin DIL package

Eﬃciency up to 77%

EMI complies with EN55032

Class B

The QD8E_3U series is is a family of cost eﬀective 0.25W single output

DC-DC converters. These converters achieve low-cost and ultra-minia-

ture DIP8 pin size. Devices are encapsulated using ﬂame retardant resin.

3KVDC Isolation

Operation temperature range:

-40°C ~ +85°C

Low ripple and noise

Industry Standard Pinout

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.
