The fiscal year ending March 31, 2016, has proven to be an unusual economic year in the history of tracking the global capacitor, resistor and inductor markets worldwide. The market environment is succumbing to the impact of forces that are both internal and external to the supply chain and almost every company in the world selling electronic components took a beating in the markets in the last fiscal quarter, unless you were selling to specific manufacturers in China who in turn were building specific types of smartphones. The real crack in the armor came mid-March 2016 when a key industry executive asked me to do a quick analysis on nine month year-on-year sales cycles for components sold into the automotive industry, as there was conflicting information about just how hot the automotive end market really was; as every piece of literature (including my December MarketEYE article) promoted the positive market opportunities for passenger compartment electronics in the coming years.

Common Mode Choke
The common-mode inductor
, or common mode choke (CM choke), is a passive electronic component used to remove EMI. Common-mode chokes are designed for high-speed applications, for switch-mode power supplies and DC power lines, circuits with poor or no grounding, and circuits with signal and noise that are "mixed", or pretty much on top of each other. This device is designed specifically for its unique frequency-selective properties, and the windings are designed for EMI suppression effectiveness. Two windings are precisely wound on a common magnetic core, and the result is a device that can scrub out noise that is "very close" to your desired frequency, and return a clear and balanced signal.
is a length of conductor, normally wire, wound into a coil (thus the nickname that some people call this device) and around a core to concentrate the magnetic force (field) and maximize the inductance. The more turns of wire in the coil, the higher the inductance value. Inductors can be found in all facets of electronic design so they are not specific to one application area. Its primary properties are to resist changes in AC (alternating current) and to store and release energy from its magnetic field.
can be made from one of two different cores, ceramic (air core) or ferrite. These inductors, when made in a ceramic core, usually possess high SRF’s and current ratings for higher frequency applications. When made in a ferrite core, the part will be naturally shielded and typically will have higher inductance values and higher Q factors at lower frequencies.
Thin Film Inductors
Thin film inductors
are the tightest tolerance inductors made. These are made specifically for High Q and high current characteristics within high frequency and lower inductance applications. Normally this would include RF and wireless applications including but not limited to the following applications: Bluetooth, Telecom Market, GPS, PDA, cellphones, etc. Typically they are used for impedance matching on your RF circuit. Another use for thin film inductors is for creating a resonant circuit (tuning a circuit).
are the most versatile of the three technologies when it comes to their use in applications. This category of inductors includes not only chip inductors, but also all leaded inductors as well. A wirewound inductor will have the option to be magnetically shielded or not which helps it control unwanted signals from interfering with other components on the board especially important in filtering applications.
