The WE-PD-family storage chokes are ideal for integrated DC/DC converters and switching controllers with output powers from 0.01 W to 300 W. The inductors help to raise the efficiency of switching controllers to over 95 percent. Whereas the “Standard” and “Robust” series have a NiZn core, the “Performance” variant with MnZn attains even higher saturation current values for the same component size.

The majority of tantalum capacitors used today are based on a solid electrolyte cathode system, and there have been many advancements in technology to enable smaller sizes, increased capacitance, and lower equivalent series resistance (ESR). Due to the relatively large market size and multiple suppliers, product improvements and new products are regularly reported and introduced to customers worldwide.

Organic Capacitor (KO-CAP) is a solid electrolytic capacitor with a conductive polymer cathode capable of delivering ultra low ESR and improved capacitance retention at high frequencies. KO-CAP combines the low ESR of multilayer ceramic, the high capacitance of aluminum electrolytic, and the volumetric efficiency of tantalum into a single surface mount package.

Introduction to Film Resistors
Film resistors are built either on cylindrical rods or on planar substrates. Usually, the material in the rods and substrates is ceramic in the state of aluminum oxide (alumina), but glass may occur. Hollow cores exist but are more and more abandoned when sizes are becoming smaller. This design suffers also from drawbacks: the construction is more fragile and the heat dissipation is poorer than that of a solid core.

Nanocrystals are crystals measuring less than 100 nanometers in at least one dimension. The smallest fundamental component of a nanocrystal is called the crystallite, or grain. Materials that have nanocrystals distributed throughout, and have significantly different characteristics, as a result, are called nanocrystalline materials. Semiconductor nanocrystals with dimensions smaller than 10 nm are also sometimes called quantum dots.
