Qualified for leadfree reflow solder
process according IPC/JEDEC
J-STD-020E
The TES 3WI series is a family of high performance 3W DC/DC-converter modules in a low profile SMD package with compact dimensions. The 14 modules
feature ultrawide 4:1 input ranges with tightly regulated output voltage. High
efficiency allows an operating temperature range of –40°C to +70°C at full
load. Further features are built-in EMI-filter to meet EN 55032 conducted class
A without external components and remote On/Off control. The products comply with IPC J-STD-020E and are qualified for high temperature lead-free reflow
solder process.
