THN 20-4823

DC/DC Converter THN 20 Series, 20 Watt • Smallest encapsulated 20 W Converter! Ultra compact size: 1.0" x 1.0" x 0.4" • Shielded metal case with isolated baseplate • • • • • Wide 2:1 input voltage ranges • • I/O isolation voltage 1500 VDC • 3-year product warranty Very high efficiency up to 90% UL 62368-1 IEC 62368-1 Output voltage adjustable Remote On/Off control Operating temp. range –40°C to +75°C and up to 85 °C with heat-sink Input filter meets EN 55022 class A without external components The THN 20 series is the latest generation of high performance DC/DC converter modules with highest power density. The product achieves 20 W output power while it comes in a metal case with dimensions of only 1.0" x 1.0" x 0.4". All models have a wide 2:1 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 75°C or 85°C 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 equipment, instrumentation, distributed power architectures in communication and industrial electronics and everywhere where space on the PCB is critical.
