PRODUCT OVERVIEW
The MINMAX MBU100 series is a range of 1W DC/DC converters in a miniature SIP Package featuring I/O-isolation of 1000VDC.
A high efficiency allows an operating temperature range of –40°C to +85°C.
These converters offer an economical solution for many space critical applications where a voltage has to be isolated i.e for noise reduction, ground loop
elimination, digital interfaces or for board level power distribution.

Notes
1 Specifications typical at Ta=+25℃, resistive load, nominal input voltage and rated output current unless otherwise noted.
2 These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not damage these
modules; however they may not meet all specifications listed.
3 We recommend to protect the converter by a slow blow fuse in the input supply line.
4 Other input and output voltage may be available, please contact factory.
5 That “natural convection” is about 20LFM but is not equal to still air (0 LFM).
6 Specifications are subject to change without notice.
