bsv-1.5s12r0h XP Power Limited, bsv-1.5s12r0h Datasheet - Page 4

• Manufacturer Part Number: bsv-1.5s12r0h
• Description: Pol Dc-dc Converter
• Manufacturer: XP Power Limited

Set this product in a place where good convection is ensured. And also be sure to mount on a board, when using.
This product has been designed to radiate by utilizing the mounted board. So make the line to connect to the converter as wide as possible.
The radiation from GND is especially big, so make the GND line wide.
The derating curve below is a data when mounted on a double-side board of copper foil thickness 70µm, copper foil area 100×100mm (both sides)
and thickness of the board 1.6mm. The radiation charateristics will change depending on the wiring, so please refer to the data.
The thermal characteristics for this converter will be largely influenced by the mounted board and the ambient condition. For this reason, finally
mount the converter into the device that will be actually mounted. And when it is operated at the maxmimun ambient temperature of the equipment,
be sure that the temperature of the board surface does not exceed 100°C.
