DESCRIPTION
The HB04U Series is a low-cost, high-isolation voltage, unregu-
lated, single and dual output DC/DC converter. The dielectric
withstand characteristics of each converter is tested in production
to ensure barrier integrity.
The HB04U Series uses advanced circuit design and packag-
ing technology to realize superior reliability and performance.
A 100kHz driven push-pull oscillator is used to ensure stable
frequency and non-saturating operation of the input stage. This
means there are no high peak voltages or currents like other
design topologies, which can reduce unit reliability. Reduced
parts count adds to the reliability of the HB04U Series.
The high efficiency of the HB04U Series means less internal
power dissipation. With less heat to dissipate, the HB04U Series
can operate over a wider ambient temperature range with no
degradation of reliable operation.
The HB04U Series offers the user low cost without sacrificing
reliability. The use of surface mounted devices and manufactur-
ing technologies make it possible to offer premium performance
at low cost.

MATERIAL: Units are encapsulated in a low thermal resistance molding compound which has excellent
chemical resistance, wide operating temperature range, and good electrical properties under high humidity
environments. The encapsulant and outer shell of the unit have UL94V-0 ratings. Lead material is brass;
lead finish is solder plated to allow ease of solderability.

4.0W Unregulated High Isolation DC/DC Converter
THROUGH-HOLE SOLDERING INFORMATION
These devices are intended for wave soldering or manual soldering.
They are not intended to be subject to surface mount processes under any circumstances.
The normal wave soldering process can be used with these devices where the device is subjected to a maximum wave temperature of 260°C for a period of
no more than 10 seconds. Within this time and temperature range, the integrity of the device’s plastic body will not be compromised and internal temperatures
within the converter will not exceed 175°C. Care should be taken to control manual soldering limits identical to that of wave soldering.
ABSOLUTE MAXIMUM RATINGS
Internal Power Dissipation.....................................................................1W
Short Circuit Duration................................................................Momentary
Lead Temperature (soldering, 10 seconds max)..............................+300°C
