Disposable primary batteries are replaced once the energy supply is depleted. Their energy is produced when the materials within the battery react and are exhausted

Fibre Channel products include hubs, directors, servers, adapters, etc

Fibre Channel connectors are high-speed connectors used in Fibre Channel systems

Data storage systems are used to store, protect and manage computer data. Many types of disk drives and tape drives are available.

Open channel flow sensors measure fluid flow through open channels

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

Hard drives are integral, non-volatile, electronic data storage units inside computers. Traditionally, hard drives were hard-wired into computers. Removeable hard disks and drives are also available.

Electrical connectors are devices that join electrical circuits together. Male connectors plug into receptacles, jacks, and outlets. Female connectors contain sockets to receive other devices.

Metal-oxide semiconductor field-effect transistors (MOSFETs) are electronic devices with a built-in capacitor as the input and a conducting channel as the output. An electrode called a gate controls the width of the channel and determines how well the MOSFET conducts

RAID controllers are computer boards that control RAID systems.

Metal shapes and stock includes metals and alloys in the form of bar, rod, beam, plate, foil and other standard shapes.

Bus extenders are used to increase cable lengths for distance-limited bus protocols.

Lithium batteries are primary batteries with a lithium anode.  They are disposable

Network and communication chips are semiconductor integrated circuits (IC) used in telecommunication devices and systems.

Roll forming services create metal shapes with uniform cross-sections. Sheets, strips, coils, wires or foils are fed between successive pairs of rollers that progressively bend and form the metal until the desired shape and cross-section is obtained.
