REDMOND, Wash. – Crane Aerospace & Electronics in Redmond, Wash., is introducing the SMHF42 space-grade DC-DC converters power supply family for systems integrators who need radiation-tolerant DC-DC converters that support 42- and 50-volt power buses.

Crane Interpoint DC-DC converters are used on satellites and space systems around the world including Mars Rovers, Cygnus, Aquarius, GLONASS, ISS, Dawn, and many more.

The SMHF42 is a family of isolated 15-Watt power electronics products with a range of single and dual outputs, operating over an input voltage range of 35 to 55 volts with 80 volt transient protection.

They are available in Class H and Class K versions (per MIL-PRF 38534) with radiation tolerance of L (50 krad(Si)) and R (100 krad(Si)).

The power supplies are reliable under harsh conditions, have small hermetically sealed packages and operate over the military temperature range of -55 to 125 degrees Celsius.

Five single-output models support 3.3-, 5, 5.2-, 12-, and 15-volt outputs; and four dual-output models supporting ±5-, ±7-, ±12-, and ±15-volt outputs. The hermetically sealed cases measure 0.33 by 1.46 by 1.13 inches.
