The THN 20WIR series is a family of ruggedized 20W DC/DC converters for highest reliability in harsh environments, expanding the company's existing railway range in the 1x1” package up to 20W. The THN 20WIR has a wide 4:1 input range and increased resistance against electromagnetic interference, shock/vibration and thermal shock and come in a compact six-side shielded 1x1” metal package.

The innovative design provides high efficiencies up to 91% and thus enables an operating temperature range from -40 to +65°C without derating. The approvals according to standards EN 50155 and EN 61373 qualify them for railway and transportation systems.

Additional qualification for the fire behavior of components according to EN 45545-2 and the safety approval according IEC/EN 62368-1, UL62368-1 support a potential compliance test of the application. Built-in features like an internal EN 55032 class A filter, input under-voltage-lockout, short circuit protection, remote On/Off and output voltage trim make this series suitable for almost any application demands and thus facilitate the design-in process.
