SMD Non-isolated Switching Regulators K78_T-500R3/1000R3 Series
    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 are introduced to meet the reflow soldering production requirements.
    The peak temperature of reflow soldering is Tc≤245 ℃ and keeps 60s (Max.) above 217 ℃, 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 ° C, without additional heat sink.

    Besides, these K78_T-R3 series also provide a wide input voltage range (4.75-36V), 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.


Features:
>SMD package
>High efficiency up to 95%
>No-load input current as low as 0.2mA
>Operating temperature range: -40℃ to +85℃
>Output short circuit protection 
>Meet  EN62368 (pending)
