Original Press Release:

Rugged High Temperature Surface Mount Isolated DC-DC Converters Conform with MIL-STD-810F Shock and Vibration

The new SU1 (1W), SU2 and SU2W (both 2W) surface mount DC-DC converters offer good thermal performance in a rugged compact package. The new SMT units also conform to MIL-STD-810F shock and vibration.

The SU1 and SU2 have a high working voltage of 250Vrms / 400VDC carrying a high isolation of 420VDC. They offer nominal 10% inputs; 3.3V and 5V with 3.3V and 5V outputs. The units are designed to meet the latest IEC 62368-1 safety standard with a wide operating temperature of -40 to 105°C (100% power to 85°C). They both pass conducted and radiated level B with (additional components) and offer dual ±3.3V and ±5V outputs variants.

The SU2W offers a wide 4:1 input in a 12V (4.5-18V) and 24V (9-36V) carrying an isolation of 3000VDC. The units are designed to meet the latest IEC 62368-1 safety standard with a wide operating temperature of -40 to 75°C at 100% power. They pass conducted and radiated level A with (additional components) in single and dual 5, 12 15V and ±12V and ±15V outputs respectively.

All parts are available in tubes or by the reel. As usual 3D models are available to download from our website to guarantee integration and pad placement. If you have an application that the SU range sounds suitable for and would like to evaluate a free sample (for customers of Great Britain), please get in touch with your FiDUS Account Manager or call us on 01183 420730.
