SMD Non-isolated Switching Regulators can withstand Reflow Soldering

October 23, 2017 by Paul Shepard

Mornsun K78 series are non-isolated regulators known for compact size, high efficiency and compatible with traditional LM78xx linear regulators. New SMD packaged K78_T-500R3/K78_T-1000R3 series have been added to meet the reflow soldering production requirements.

The peak temperature of reflow soldering is Tc≤245 degrees and keeps 60s (Max.) above 217 degrees C, which meets the IPC/JEDEC J-STD-020D.1 standard. Dimension is 15.24*11.40*8.25mm (about 0.6*0.45*0.32 inch). Efficiency is up to 95% and operating temperature ranges from -40 to +85 degrees C, without additional heat sink.

Besides, these K78_T-R3 series also provide a wide input voltage range (4.75- to 36-Vdc), continuous short-circuit protection, adjustable output voltage (±10%) and remote voltage control and so on, which can be widely used in industrial control, grid power, instrumentation, mining and other related industries.
