Resonators are frequency-selective electronic circuits that can produce a fixed (resonant) frequency when properly excited. The value of the resonant frequency depends on the circuit’s components (e.g., inductors, resistors, capacitors, crystals, etc

Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs.

Mechanical feedthroughs transmit mechanical motion through the walls of a vacuum system. Both linear and rotary feedthroughs are included in this grouping

Fluid feedthroughs use a hermetic seal to transmit fluids through the walls of a pressurized or vacuum system. Devices include nitrogen, air, and water feedthroughs

Fiber optic connectors are used to align and join two or more fibers together to provide a means for attaching to, or decoupling from, a transmitter, receiver, or other fiber optic device.

IC sockets and headers are board-mounted female connectors that serve as carriers for integrated circuit (IC) chips.

IC sockets and interconnect components interface or connect a microelectronic semiconductor chip to a board or larger scale device.

Feedthroughs transmit electrical current, fluids, optical signals, or mechanical motion through the walls of a pressurized or vacuum system through a hermetic seal

Current sensing resistors convert the current flowing through it to a voltage drop. Monitoring or measuring this voltage drop allows the current through the resistor to be measured. Applications for current sensing resistors include power supplies, receptacles, and battery packs. 

Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed or variable loss. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. They are also used to test the linearity and dynamic range of photo sensors and photo detectors.

Current sense transformers are used to detect and measure current. There are two basic types of products: switch-mode transformers for power conversion applications, and precision-measurement transformers for instrumentation applications.

Resistors are electrical components that oppose the flow of either direct or alternating current. They are used to protect, operate, or control circuits.

Metal oxide varistors (MOV) are semiconductors that protect electronic components and systems from transient voltages.

Electronics assembly service companies based on providing contract design, manufacturing, and related product support services on behalf of electronics OEMs.

Varistors are voltage-clamping devices that can absorb current without damage. They are typically used in surge protection devices.
