Details
Litz wires, composed of multiple bunched, individually insulated wires, are ideal for applications demanding flexibility and high-frequency performance. In response to growing customer demand for innovative, high-quality products, Rubadue began supplying a wide range of high-frequency litz wires.
Given the diverse applications, Rubadue offers several types of litz wires to meet various requirements.
In the early 20th century, litz wire usage was aligned with the technological advancements of the time. For instance, in 1923, litz wires enabled the first medium-frequency radio broadcast. In the 1940s, they were crucial in developing the first ultrasonic diagnostic systems and basic RFID technology. By the 1950s, litz wire was used in USW chokes. As electronic components rapidly advanced in the latter half of the century, the use of litz wire expanded significantly.
Litz wire mitigates losses due to skin and proximity effects at high frequencies while offering greater mechanical flexibility than single-wire alternatives.
