Resistors are used in all electronic circuits to restrict current flow. Resistive products manufactured by Vishay Intertechnology include single (discrete) resistors based on thin film, thick film, metal electrode leadless face (MELF), metal oxide film, plasticfilm, carbon film, and wirewound technologies; Power Metal Strip^® resistors; battery management shunts; fuses; and pyrotechnic initiators and igniters. Vishay Intertechnology manufactures resistor networks and arrays, in which multiple resistors are combined in a single package. The Company also manufactures non-linear resistors, which suppress voltage increases due to temperature and voltage changes, as well as variable resistors, including potentiometers, trimmers, sensors, and magnetic encoders. Vishay Intertechnology innovations include industry-first Power Metal Strip^® resistors for precision current monitoring of sensitive circuits, such as those in electric power meters, industrial systems, and automotive electronic controls for engines, transmissions, and pollution reduction systems. They are ideal for all types of current sensing, voltage division, and pulse applications. The Power Metal Strip family includes very high-power versions. Other innovative resistive products include high-temperature chip resistor arrays (with operating temperatures of up to 230 °C), water-cooled power resistors (with power ratings up to 2500 watts), thermal fuses for automotive applications, and miniature thick film resistors for hearing aids and high-frequency probe tips, to name just a few.

Vishay Intertechnology has a broad line of both standard and custom inductors and transformers that are used in a wide variety of applications, from RF signal filtering to DC/DC power conversion.With an offering that ranges from miniature chip inductors to complex, multi-terminal devices, Vishay Intertechnology has one of the broadest standard product lines of any magnetics manufacturer. Vishay Intertechnology is recognized as a market leader in custom magnetics used in implantable and external medical devices, instrumentation, avionics and aerospace controls, industrial equipment, and alternative energy systems. Vishay Intertechnology is one of the largest suppliers of high-reliability custom magnetics in North America. Vishay Intertechnology innovations include patented IHLP^® inductors, which feature higher frequency operation, higher current ratings, better temperature stability, and smaller sizes than competing devices. These inductors are used as energy storage devices for DC/DC converters and high-current filters for computers, tablets, disc drives, industrial systems, and automotive applications. The IHLP inductor family is always expanding and includes composite-coupled inductors designed for SEPIC DC/DC converters, dual inductors for Class D amplifiers, and a variety of unique products for today's power supply and high-current filter applications. Vishay Intertechnology also provides wireless charging coils, crystals, oscillators, specialized coaxial and edgeboard connectors, and specialty power supplies.

Capacitors are used in almost all electronic circuits to store energy and discharge it when needed. Applications include power conversion, DC linking, frequency conversion, bypass, decoupling, and filtering. Types of capacitors manufactured by Vishay Intertechnology include tantalum (both solid and wet), ceramic (both multilayer chip and disc), film, power, heavy-current, and electrolytic aluminum. Vishay Intertechnology capacitors range from tiny surface-mount devices for hearing aids and mobile devices to large heavy-current capacitors used in industrial applications. Vishay Intertechnology innovations include metalized film power capacitors with the highest RMS current rating for their size in the industry, non-magnetic multilayer ceramic chip capacitors optimized for use in MRI equipment and other end products, MICROTAN^® tantalum capacitors with proprietary multi-array packaging (MAP) that provides a significant reduction in DC leakage and better stability, the industry's first wet tantalum capacitors in true surface-mountable molded packages formission-critical applications, and ultra-stable QUAD HIFREQ multilayer chip capacitors (MLCCs) for RF applications. Vishay Intertechnology also manufactures ENYCAP™ hybrid energy storage capacitors that feature industry-high energy density.
