Valued Customer:

For more than 47 years, T.J. Assemblies has lived by a core value to "treat every customer like they are our only customer". This enduring value guides us as we face the difficult challenge of responding to the coronavirus (COVID-19).

During the coronavirus outbreak, our focus is on the safety and well-being of our employees, who are vitally important to support you and your business, as well as the communities where we operate. Our second primary area of concern is the safety and continued service of our customers.

Due to the state mandated "shelter in place" shutdown here in Illinois we have ceased production on any non-essential parts as stipulated by the state of Illinois and Homeland Security. If your part qualifies as an essential component for military, critical infrastructure, or medical applications please notify us and we will initiate production to maintain the supply of the component. During the shutdown we will continue to take orders, provide customer service, and respond to emails. Please contact us by email as the office will have limited hours: Contact Us

Currently we are planning on reopening production on June 1st to resume normal operations. We will continue to follow guidance from local, state, and federal authorities regarding further developments and will communicate any changes on this web page.

As always, thank you for being a valued customer and for your continued trust as we manage through this difficult time together.

T.J. Assemblies Management

T.J. Assemblies is a manufacturer of bobbins, coil forms and electronic components for the coil winding and electronics industry. Our catalog features a complete line of standard bobbins for motors, relays, transformers, chokes, ballasts, etc., along with toroid mounts, headers and components. In addition to these standard products, we also provide custom designed bobbins and thermoplastic components, with or without terminal assembly, to meet your manufacturing and production requirements. Contract pinning or terminating service is also available. We specialize in virtually any type of termination required in a bobbin or thermoplastic component: wire pins, stamped or formed terminals, and rivets. Our low cost in house tooling and manufacturing facilities make use of CAD/CAM methods and state of the art high production automatic or semi-automatic micro-processor controlled equipment. This results in reduced costs, higher quality and superior performance of the finished product.

Our recent purchase of the United Technical Products line of bobbins and components further enhanced out ability to serve our customers more completely.  Please click here to view the UTP Catalog.
