1.3. Marking Code
All Hall sensors have a marking on the package sur-
face (branded side). This marking includes the name
of the sensor and the temperature range.

1.4. Operating Junction Temperature Range
The Hall sensors from Micronas are specified to the
chip temperature (junction temperature T_J).
K: T_J = −40 °C to +140 °C
E: T_J = −40 °C to +100 °C
Note: Due to power dissipation, there is a difference
between the ambient temperature (T_A) and junc-
tion temperature. Please refer to section 5.1. on
page 27 for details.

Hall sensors are available in a wide variety of packag-
ing versions and quantities. For more detailed informa-
tion, please refer to the brochure: “Hall Sensors:
Ordering Codes, Packaging, Handling”.
1.6. Solderability and Welding
Soldering
During soldering reflow processing and manual
reworking, a component body temperature of 260 °C
should not be exceeded.
Welding
Device terminals should be compatible with laser and
resistance welding. Please note that the success of
the welding process is subject to different welding
parameters which will vary according to the welding
technique used. A very close control of the welding
parameters is absolutely necessary in order to reach
satisfying results. Micronas, therefore, does not give
any implied or express warranty as to the ability to
weld the component.
