SMHF 100 krad(Si) Converter The SMHF Series DC-DC converters now operate up to 45V input and offer up to 15 watts of output power with single outputs of 2.5, 3.3 and single or dual outputs of 5, 12 or 15 VDC. The SMHF converters now offer reduced output ripple noise, improved start-up response and recovery and improved step load response and recovery. They operate over the full military temperature range of -55 to +125 °C, the small footprint of 1.48 x 1.13 x 0.33 inches saves board space for critical missions. The SMHF converters offer screening options to Space Prototype (O), Class H or Class K and Radiation Hardness Assurance (RHA) levels of “-” (O, no rating), “P” 50 krad (Si) or “R”, 100 krad (Si) per MIL-PRF-38534.
