Newly Issued Patent for Applying a Conductive Coating onto an Insulator of an X-Ray Tube

LaFox, IL | March 15, 2022 – Richardson Electronics, Ltd. (NASDAQ: RELL), which is a global provider of engineered solutions for diagnostic imaging equipment, is pleased to announce the issuance of U.S. Patent No. 11,257,652 (the ’652 Patent). The ’652 Patent is a result of Richardson’s innovative healthcare solutions for replacing X-ray tube components. Richardson’s newly-patented solution provides a unique conductive coating to an X-ray tube insulator. The insulator is easier to manufacture, prevents component failure, and increases recyclability. The coating can be advantageously applied at a relatively low temperature that does not negatively impact sensitive portions of the insulator. The innovative solution also reduces waste, as the coating can be reapplied numerous times to the ceramic components. The ’652 Patent is yet another confirmation of Richardson’s desire for providing its customers with the latest technological advancements.

“We are thrilled to receive this patent from the U.S. Patent Office.  Richardson Healthcare’s engineering team develops solutions to help reduce the cost of healthcare.  New solutions like the conductive coating not only reduce the cost of the tube, making it more affordable for hospitals but also allow us to recycle components which in turn reduces waste,” said Wendy Diddell, Richardson Electronics’ Executive Vice President and Chief Operating Officer.

Richardson Healthcare plans to introduce this technology in its future CT tube manufacturing programs.

Announcing SemiQ’s 1200V 80mΩ Silicon Carbide MOSFET

LaFox, IL, January 26, 2022 – Richardson Electronics, Ltd. (NASDAQ: RELL) announces the availability of SemiQ’s 2nd generation silicon carbide power switches, 1200V 80mΩ SiC MOSFETs. These MOSFETs complement SemiQ’s existing SiC rectifiers at 650V, 1200V, and 1700V.

SemiQ has engineered two new MOSFETs, GP2T080A120U (TO-247-3L) and GP2T080A120H (TO-247-4L), to provide the best trade-off of conduction and switching losses. These new products give designers more flexibility over a broader range of applications in comparison to other devices on the market. Samples are available upon request; please contact a Richardson Electronics representative.

SiC MOSFETs bring high efficiency to high-performance applications including electric vehicles, power supplies and data centers and are specifically designed and tested to operate reliably in extreme environments. Compared to legacy silicon IGBTs, SemiQ’s MOSFETs switch faster with lower losses, enabling system-level benefits through reduced size, weight, and cooling requirements.

“SemiQ has gone above and beyond in their continued investment in this wide-band gap technology,” stated Richardson’s Greg Peloquin, Executive Vice-President, Power and Microwave Technologies Group. “The addition of their Silicon Carbide MOSFET technology allows for the expansion of demand creation capabilities in a number of applications.”
