Exxelia Ohmcraft Precision Resistors Help Ensure Reliability of the Powerful Minuteman III Intercontinental-Range Missile

ROCHESTER, N.Y., November 11, 2020 — Intercontinental-range ballistic missiles (ICBM) such as the Minuteman III—the only land-based ICBM missile in service in the U.S.—have the ability to travel more than 5,500 kilometers (3,400 miles) to hit their targets. To ensure the highest possible degree of a...

The United States’ Minuteman III missiles are stored in the Great Plains, lying dormant for years while withstanding the sometimes-harsh environmental conditions. They must be ready for deployment at any given moment, and the Minuteman III boasts nearly 100 percent testing reliability.

“Since first coming into service in 1970, there have been several upgrades to the Minuteman III missile,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “To keep the ICBM modernized and ensure its product performance throughout the years, military contractors turned to Exxelia Ohmcraft to develop the custom resistors required to support the missile’s rigorous precision and reliability specifications.”

Exxelia Ohmcraft performs a full range of military lot acceptance testing (LAT) on its resistors to meet the unique design requirements for each particular application. In the case of the Minuteman III, the resistors’ small form factor was crucial to keeping the missile as lightweight as possible.

Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.

New entity, Exxelia Magnetics

This is an internal merger of two innovative, professional and complementary companies both designer and manufacturer of high-end would magnetic components, which have a history of successfully working together for a year. Exxelia Magnetics will have greater scale, breadth and capabilities to compete more effectively in the global marketplace. Exxelia Microspire Microspire was founded in 1978 and became part of Exxelia Group in 2008. Exxelia Microspire has been designing, developing and manufacturing wound components for over 35 years: transformers and inductors, electro-magnets, rotors and stators. Exxelia Microspire has several manufacturing sites, notably newly located low production cost facilities offering competitive solutions. Exxelia Microspire’s know-how includes standard winding technologies: linear (in RM, ETD, EP, EFD, ER, EQ and other formats) and toroid. For harsh environment applications with shock, vibration, and high temperature issues, Microspire offers innovative specific technologies including SESI, TT and CCM. Exxelia Microspire’s qualified technologies, clearly defined design rules and industrial organization provide the platform on which it is able to offer its customers optimal solutions. Exxelia N'Ergy Exxelia N’Ergy (ex N’Ergy) was acquired in 2015 by Exxelia Group.  Exxelia N’Ergy designs and manufactures passive specific electromagnetic components in small and medium range: Transformers, Chokes, Sensors (tachometer, gyros, …), Electromagnets.
