DC/DC Converters THN 20WI Series, 20 Watt Features Smallest encapsulated 20W Converter! CndBing pULe 60950-1 Scheme Ultra compact size: 1.0" x 1.0" x 0.4" UL 60950-1 Shielded metal case with isolated baseplate Ultrawide 4:1 input voltage ranges Very high efficiency up to 90% Output voltage adjustable Remote On/Off control Operating temp. range -40C to +75C and up to 85 C with heat-sink I/O isolation voltage 1500 VDC Input filter meets EN 55022 class A without external components No minimum load required Lead free design, RoHS compliant 3-year product warranty The THN-20WI series is the latest generation of high performance dc-dc converter modules with highest power density. The product achieves 20W output power while it comes in a metal case with dimensions of only 1.0"x 1.0"x 0.4". All models have an ultra wide 4:1 input voltage range and precisely regulated output voltages, even under no load conditions. Highest efficiency of up to 90% makes this product very reliable and applicable in temperature ranges of up to 75C or 85C with optional mounted heat sink. Together with low input current characteristics at minimal load and remote On/Off control these converters are the ideal solution for battery-operated systems. Typical applications are in mobile equipments, instrumentation, distributed power architectures in communication and industrial electronics and everywhere where space on the PCB is critical.
