Signal filters block or decrease (attenuate) unwanted frequencies or signal wave characteristics.

Active low pass filters pass signals from low frequencies and reject signals from high frequencies.

Active filters are electronic filers that use active components such as voltage amplifiers or operational amplifiers. The amplifier shapes and stabilizes the behavior of the filter, and serves as a buffer interface to the driven component.

Active band pass filters are used to attenuate frequencies below and above a range of frequencies (i.e., the bandwidth or passband of the filter).

IC electronic filters are frequency-selective circuits that consist of devices such resistors, capacitors, inductors, transistors, or operational amplifiers coupled with reactive components.

Cable assemblies are collections of wires or cables banded into a single unit with connectors on at least one end.

Channel service units (CSU) and data service units (DSU) are digital interface devices that connect end user data communications equipment to digital access lines. They also provide framing of sub-64 kbps customer access channels onto higher rate data circuits.

Ethernet cable assemblies are designed to support Ethernet, a standard protocol for the connection of computers in a local area network (LAN). Choices include 10Base-T, 10Base-2, 10Base-FL, 100Base-TX, 100Base-FX, 1000Base-T, 1000Base-LX, and 1000Base-SX.

Coaxial cables have one conductor insulated with a dielectric material and then surrounded by the other conductor, usually referred to as the center conductor and shield.  Triaxial cables are specialized coaxial cables.

Serial cable assemblies are used for the serial transmission of data. They support communication standards such as RS232, RS422, and RS485, as well as Fibre Channel, FireWire or IEEE 1394, USB 1.1, and USB 2.0.

Serial communication adapters provide one or more serial ports to a host computer. They interface with the host computer via a data bus and add RS232, RS422, RS485 and/or other types of serial ports.

Dielectric greases and insulating fluids are insulating oils, greases, transformer oils and fluids that have a high dielectric strength and are used in transformers, capacitors, EDM machining, and other electrical device applications.

Data acquisition computer boards are self-contained printed circuit boards that typically plug into the backplane, motherboard, or otherwise interface directly with the computer bus.

Dielectric ceramics and substrates are electrical insulators with dielectric strength, dielectric constant and loss tangent values tailored for specific device applications.

Conformal coatings encapsulate circuit boards and their electronic components in order to prevent the ingress of moisture, fungus, dust and other environmental contaminants.
