Please be advised that due to the ongoing supply issues with raw materials affecting the global electronics industry, as well as an increase in orders received by our manufacturing partners, a large number of products are facing increased lead times in recent months. For the latest lead time and stock availability, please contact one of our engineers who will be happy to discuss lead times further and the potential for alternative parts.
UL
Underwriters Laboratories® Inc. (UL) is an independent product safety certification organization Based in Northbrook, Illinois.
UL develops standards and test procedures for products, materials, components, assemblies, tools and equipment, chiefly dealing with product safety.
UL does not “approve” products. Rather it evaluates products, components, materials and systems for compliance to specific requirements, and permits acceptable products to carry a UL certification mark, as long as they remain compliant with the standards.
