Rated Current

This value describes the direct current at which the component self heating increases by 40 Kelvin. ∆T = 40K

The method Würth Elektronik uses to measure the rated current is based upon section 6 of the IEC 62024-2:2020 standard to provide transparent and comparable IR values. A test PCB with a soldered Power Inductor is contained within a box of roughly 40 cm on each side. The Component and the PCB do not contact directly with the surrounding box. Only natural heat exchange occurs, with no forced heat transfer e.g. airflow, applied to the test PCB.

They are different methods to measure the temperature. Würth Elektronik decided to use an infrared camera to reliably detect and measure the hottest area of the component. In order to prevent measurement error, the test PCB is prepared with a black coating.

To determine the 40 K self-heating mentioned above, the current flowing through the component is increased step by step. The temperature is considered to have stabilized as soon as the heating is reduced to less than 1 K per minute during a current step. The time it takes for the temperature to stabilize also depends on the volume and material composition of the inductor.

The diagram shows how the rated current measurement is set up

Influence of PCB Trace Dimensions on Rated Current

The self-heating of the power inductor is influenced by the dimensions of the conductor traces on which it is soldered.

A small conductor trace cross-section is less able to transport heat. The power inductor can therefore only dissipate the heat from the current via the air. The self-heating of 40 K is already achieved at a low current.

A larger cross-sectional area reduces the thermal resistance. Wide conductor traces with a large copper surface increase the heat flow, which means that the inductance can dissipate the self-heating better via the conductor traces. The component can be operated with higher currents as the self-heating of 40 K is only achieved at a higher current.

Rated Current & Performance Rated Current

Table with different electrical characteristics and values

In some datasheets there is more than one Rated current specified.

The Rated Current is measured without the IEC standard.

The Performane Rated Current is measured by using the conditions specified in the IEC standard.

Technical graphic comparing the WE legacy Platine

Due to the range of sizes and construction types of the Würth Elektronik product line-up, different PCB layouts are used to measure the rated current.

The WE-legacy PCB are used to measre the rated current as defined in some datasheet whereas the Performance Rated Current in the datasheet is measured by using the Iclass PCBs.

The diagram shows the temperature increase, the current and the inductance as a function of each other

IR = WE-LHMI measured on the WE legacy PCB,
IRP = WE-LHMI measured on IIclass C PCB,
5 mm = WE-LHMI measured on 5 mm trace width,
FC: Forced Convection

Different PCBs and forced convection influence the rated current.

Lack of transparency about the test conditions makes it difficult to compare different rated currents data.

Würth Elektronik avoids this issue by using the IEC Standard.

Image 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.
