Operating temperature is the minimum and maximum range of ambient temperatures that a component can be safely operated. The maximum operating temperature is defined as the magnetics device internal self-temperature rise plus the maximum application ambient temperature exposed to the magnetics. The minimum operating temperature is defined as the absolute minimum application ambient temperature exposed to the magnetics. See Magnetics operating temperature defined application note for more detail.

On some product data sheets a maximum frequency of over 1 MHz is shown but the Irms derating curve only goes up to a few hundred kHz, why?
The maximum frequency shown is the frequency at which the inductance will start to roll off. The de-rating curve is limited by the information the core manufacture supplies, generally the inductors can be used beyond the highest de-rating frequency without any issues. For example, the SD family has been used at up to 2 MHz (with relatively low applied V-μs, about 10-20 percent of the rated V-μs).
What is the termination finish and terminal material?
Please contact technical support.
Typically magnetics MSL=1. Please contact technical support for verification.
Do you have 3D models (.STEP)?
Please contact technical support for availability.
Theta JA, Theta JC, Rja and Rjb are terms applicable only to active devices, such as integrated circuits. Inductors do not contain semiconductor material junctions and so do not have the same potential failure modes. Theta JA and Theta JC are therefore not applicable to inductors.
Unlike capacitors or diodes, single winding inductors do not have a functional polarity and work equally in either direction, so polarity is not important in most end-use circuits. On rare occasions, it has been reported that some inductors perform better when mounted in one particular orientation, due to interaction with nearby components or ground plane conductors. Any asymmetrical performance is very much a function of the application, especially board layout.
What is the inductor thermal resistance?
Thermal resistance is not typically specified for inductors because inductors are rated by current and not by power. You can approximate the thermal resistance by dividing the temperature rise due to Irms current (e.g. 40 °C rise) by the DCR times the square of the Irms rating: Rth (in °C/W) = 40 °C ÷ (DCR × Irms^2) where DCR is in Ohms and Irms is in amps.

Do you perform ESD testing on your components?
ESD testing is typically performed on active devices. Our magnetics products are passive devices and not typically susceptible to ESD damage so we do not usually test for ESD damage. We recommend customers perform their own application specific ESD testing if necessary. Please contact technical support if you have further questions.
Can you provide a REACH certificate stating the REACH status?
Please see our REACH statement for contact information or contact technical support.

What is Fit Form and Function?
We define fit, form and function as follows:
Fit – the ability of a part to physically interface with, connect to, or become an integral part of another part (i.e footprint)
Form – the shape, size, dimensions, mass, weight and other visual parameters that uniquely distinguish a part.
Function – the action or actions that a part is designed to perform (i.e electrical characteristics, performance curves)

Yes, as long as the peak current rating is not exceeded, and the device surface temperature is limited to its maximum rating.
The ratings for Irms and Isat are an indication of the inductor performance, in practice the inductor should not be used beyond its Isat rating.
The maximum frequency shown is the frequency at which the inductance will start to roll off. The de-rating curve is limited by the information the core manufacture supplies, generally the inductors can be used beyond the highest de-rating frequency without any issues.

Inductor power ratings are not specified because the more meaningful rating for inductors is the Rms current rating. Inductor Rms current ratings are derived by applying DC or low frequency AC current and measuring the temperature rise.

We do not believe storage temperature of -55 °C will be an issue. However, we have not tested these parts at -55 °C and do not have any data to confirm or deny this theory.
