Engineered for design engineers working in demanding power electronics environments, these new tape wrap offerings allow for increased safety and tighter coil winding geometries while maintaining electrical integrity at elevated temperatures.
Rubadue continues to lead the industry by delivering products and solutions that engineers can count on—every time, without compromise.
A New Tool for High-Frequency Designs
Tape-wrapped Litz wire is a well-established solution in high-frequency applications. Rubadue's offering includes:
- PET (Class F, 155°C) tape insulation, commonly referred to in industry as Mylar, and direct solderable
- Polyimide (Class H, 180°C or higher) tape insulation, known for exceptional thermal performance and lead-free reflow compatibility
"Tape wrapping gives our customers another resource in their design toolbox," said Kyle Jenson, Director of Business Development at Rubadue. "It's a critical addition to our manufacturing capabilities because engineers now can choose the optimal insulation method for their specific application without sacrificing turnaround or quality. And, they gain access to insulations on Litz wires larger than 8 AWG."
Expanded Capabilities for Custom Requirements
With the installation of new production equipment, Rubadue can now support larger conductor diameters and a broader range of Litz configurations. This makes the company's offering ideal for industries including:
- e-Mobility (EV charging, off-highway and agricultural vehicles)
- Aerospace and Defense (high-reliability, low-weight power supply systems)
- Medical Equipment (custom power supplies for imaging and diagnostic systems)
- Industrial Automation (robotics and welding systems)
As with all Rubadue products, tape-wrapped Litz wire is backed by deep engineering support, rapid prototyping capabilities, and low minimum order quantities to meet the needs of both R&D and production teams. Whether you're designing for a startup prototype or a critical production run, Rubadue delivers unmatched quality and technical support—making us the premier wire partner for leading OEMs.
Environmentally Responsible, Electrically Reliable
Rubadue's tape wrap materials are PFAS-free and non-halogenated, helping customers meet increasing environmental and regulatory expectations. Their high dielectric strength enhances safety in high-voltage applications, while thin insulation layers improve fill factor in compact designs.
Domestic Manufacturing, Global Service
All tape-wrapped Litz wire is manufactured in the U.S., offering customers a stable, right-shored supply chain and short lead times. For global customers, Rubadue provides seamless service and support through its established supply network.
Customers choose Rubadue not just because we deliver wire—they choose us because we deliver peace of mind. When performance is critical and there's no room for error, Rubadue is the only name that belongs on your BOM.
Rubadue is currently accepting orders for this new capability. Design engineers interested in evaluating tape-wrapped Litz wire can request samples through Rubadue's website or contact their sales representative directly.
