Did you know that when you’re searching for an inductor, one of the first parameters you need to check, besides inductance, is the current rating?

In this video you can find why the rated current of an inductor is just as important as the inductance itself.

The video talks about DC resistance, self-heating, and get...

Switching DC-DCs regulate the output voltage based on energy flow into and from the DC-DC by controlling the duty cycle of the on and off states. When the switch is conducting, energy flows from the input source into the converter and in the case of a buck, some of this gets stored in the inductor as magnetic energy (0.5*LI2) while some gets delivered directly to the output (forward topology).

A fuse is an electrical or electronic circuit protection device that protects a circuit against overcurrent, either by melting or fusing open its conductive element when excessive current flows through it. Some fuses are single-use or “one-shot” designs; others are reusable designs. This is an important distinction in the marketplace among design engineers.

Paper Capacitors

Because paper is porous it has to be impregnated in order to prevent corona effects and flash-overs. It is done by use of melted wax or different kinds of oils, among other things mineral and silicone oils. The oils increase the tensional stability but decrease to a certain extent the εr. A fibrous paper has a εr ≈ 6.6 and the mineral oil ≈ 2.3 which gives the impregnated winding a εr varying between 3.1 and 4.5. The differences depend above all on the winding pressure produced by the tensile force during winding.

Kemet Webinar

MLCCs are the most common type of capacitor out there. Almost every single electronic device uses MLCCs in a multitude of applications. We all know what MLCC stands for (multilayer ceramic capacitor), but do you know how they are made? What are the different types and how to choose from among all the...

Pros and Cons of MLCC Downsizing

  • Posted by doEEEt Media Group
  • On January 25, 2021
  • 0
Advantages and disadvantages of MLCC downsizing are discussed in AVX technical papers written by Frank Hodgkinson and Maureen Strawhorne. As integrated circuits (ICs) continue to pack more functionality into smaller packages, the need for bulk off-chip capacitance remains. In resonant circuits, such as phase-lock-loops (PLLs) and switching regulators, precision class one ceramic capacitor may be required.
