Featured EMC Products
Winding metal magnetic material
The Model H-550 Turns-Counting Dial is a 46mm diameter dial which touts a metalized plastic finish that gives it a professional look of true metal dials. It can be used in several industrial applications requiring human interface such as medical instrumentation for non-critical life support applications, and test and automation equipment.
Bourns® Power TVS (PTVS) Products are high current bidirectional Transient Voltage Suppressor (TVS) diodes designed for use in AC line protection and high power DC bus clamping applications.
Bourns introduces eight new semi-shielded power inductor series - Model SRN2010, SRN2012, SRN2510, SRN2512, SRN4012, SRN4012T, SRN4026, SRN5040 and SRN6028, designed using semi-magnetic shielding technology.

After slipping below the 100-point mark indicating business optimism in December, the Global Purchasing Index surged 19% to a reading of 118 in January as buyers of electronic components reported better business conditions at the start of 2015.
Though GPI panel members reported a 3% drop in new orders from customers during the month, they said they expect orders to pick up later in the first quarter and in the second quarter of the year. They also reported an increase in their purchasing activity along with an increase in their electronic component inventories. Keep reading...

Inductors play a fundamental role in the design and development of switch-mode power supplies (SMPS). All three primary SMPS topologies − step-down (buck), step-up (boost), and step-up/down (buck-boost or inverter) − include an inductor along with a MOSFET switch, a diode, and an output capacitor.

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.
