High-rel 40W DC/DC converter offers 10 year warranty
Japanese company Cosel Co, Ltd has released of a very high reliability 40W DC/DC converter packaged in an industry standard 25.4x25.4x9.9mm, six sided, shielded metallic case. The MGF40 series has been designed to Cosel’s strict criteria for high performance and reliability, contributing to the company’s world class quality with a failure rate of below 30 parts-per-million (ppm).

Negative logic is provided as standard, the unit is ON when the RC pin is at a low level and OFF when it is at a high. It is possible to order the MGF40 with positive logic, option-R. A control pin allows the user to turn the unit ON/OFF remotely. For applications requiring lower leakage current or no Y-capacitor connected between the input and the output, an option-G is available.

Calculated in accordance with the Telcordia reliability prediction procedure Issue 4 of SR-332, at 100% load and at +25C ambient temperature the MGF40 series has a very high MTBF of 3,153,843 hours, and 675,688 hours at +60C ambient. Calculations are at ground fixed, controlled (GB).

Built with robustness in mind, the MGF40 series has been tested to sustain rough conditions and has passed three axis vibration testing equivalent to 10G and shock testing of 50G.

Housed in a metallic six sided, shielded case with high attenuation input filter, the MGF40 series offers excellent EMI performance, with figures being far below the EN55032:2012 Class A in conduction and radiated emission at 3 meters. The MGF40 has an input-output isolation of 1500VDC, an input and output to case isolation of 1000VDC, and is UL62368-1, C-UL [CSA62368-1) and EN62368-1 approved.
