September 13, 2017 by Paul Shepard

Crane Aerospace & Electronics announced the introduction of a new space-grade dc-dc converter family. The SMHF42 is a family of fully-isolated, 15-Watt products with a range of single- and dual-outputs, operating over an input voltage range of 35- to 55-Vdc with 80-Volt transient protection.

According to Bob Myers, Sr. Director of Crane’s Modular Power Solution, “Our new SMHF42 was designed specifically for customers needing radiation tolerant dc-dc converters that support 42-Volt and 50-Volt power busses.”

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)). They are highly reliable under harsh conditions, have small, hermetically sealed packages and operate over the full military temperature range of -55°C to +125°C.

There are five single output models supporting 3.3-, 5-, 5.2-, 12-, and 15-Vdc outputs; and four dual output models supporting ±5Vdc, ±7Vdc, ±12Vdc, and ±15Vdc outputs. The hermetically-sealed cases are 0.330 x 1.460 x 1.130 inches (8.38 x 37.08 x 28.70 mm).
