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.

The automotive cockpit electronics market is undergoing a transition to greater electronic content over the next five years with values increasing by a cumulative rate of an estimated 60%. Significant expansion is expected in connectivity, HUD and telematics as is shown in Figure 1 below.
Discrete semiconductor products are available at TTI Inc. from industry leading manufacturers. TTI is an authorized distributor for many sensor manufacturers including: Aeroflex Metelics, Semelab / TT electronics, Toshiba, Kingbright and Littelfuse.
(BJT) Bipolar junction transistors
are a type of transistor used in applications for amplification and switching signals. They are named Bipolar as their operations involves both electrons and holes (opposite of electrons). Similar to the MOSFET, the bipolar transistor is used in applications where signal switching or amplification is required.
is a component that allows an electric current to flow in one direction, but blocks it in the opposite direction, like an electronic version of a check valve.
Circuits that require current flow in only one direction typically include one or more diodes in the circuit design.
ransistor or IGBT
is a three terminal power semiconductor device that is noted for high efficiency and fast switching. IGBT’s are used to switch power in many electrical appliances: variable speed refrigerators, air conditioners, stereo systems with digital amplifiers. IGBT’s are a fairly recent invention beginning in the 1980’s and 1990’s. They rival the speed of MOSFET's with the ability to handle very large amounts of current and voltage. IGBT’s are often selected in lieu of MOSFETs in applications over 600 volts. IGBT’s are a major component in electric and hybrid automobiles.
ransistor) is an electronic device used to amplify or switch electronic signals. MOSFET's are the most common field effect transistor (FET) in both digital and analog circuits. MOSFET's are an enhancement on bipolar technology and are the most popular semiconductor-type transistor. A MOSFET provides both an output current and voltage gain into an external load that exceeds the input current and voltage. In basic terms MOSFET's amplify their input signals.
N-Channel & P-Channel MOSFETs
N-Channel & P-Channel MOSFETs
are specific types of MOSFETs. Silicon is “doped” by adding a slight impurity to the silicon to result in an extra electron or a reduction of one electron. N-channel devices have an extra electron in their base structure while the P-channel device are missing electrons.
is a diode operating above 0.5amps and converts alternating current (AC) to direct current (DC) in a process known as rectification
. Devices that convert the opposite (DC to AC) are know as inverters. Rectifiers are most commonly found in power supplies. Rectifiers can take standard AC electricity from power outlets and make the power usable in DC circuits. They are also used for signal conditioning. Rectifiers are also known as power diodes and are the largest class of products in the diode family. Devices with a current under 0.5amps are considered small signal diodes.
is a semiconductor device commonly used as an amplifier or an electrically controlled switch. The transistor is used in a wide variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillators because of its fast response and accuracy. Modern transistors are divided into two main categories: bipolar transistors and field effect transistors (FETs).
