Redefining Rated Current Measurements for Power Inductors

Würth Elektronik employs transparent measurement methods in accordance with Section 6 of the IEC 62024-2:2020 standard to determine the rated current (Ir) for temperature rise in power inductors. Utilizing a 20 cm test PCB within a box, natural convection occurs without direct contact with the surrounding box. Instead of a thermocouple, an infrared camera is used to avoid measurement errors and capture the hottest external point of the core. Temperature stabilizes during current passage at less than 1 °C per minute.
