Coefficient of Thermal - In accordance with DIN EN ISO 53752, the coefficient of thermal expansion is defined as a fractional increase in length per unit rise in temperature. The coefficient of thermal expansion for a material is usually specified over a temperature range because it varies depending on the temperatures. The following values are given for a temperature around 20 ¢XC. CTE is usually given in units of um/m/¢XC or ppm/¢XC.

Collisions - On a half-duplex Ethernet link, each computer must share the bandwidth with the rest of the computers. If two or more computers on a network broadcast at the same time, the packets ¡§collide¡¨ and are unreadable.This event is known as a collision.On full-duplex links,this is a non-event because there are separate transmit and receive paths.

Conduit - A tube or trough in which insulated wires and cables are passed.

Conflict of Materials Use - Worldwide attention is focusing on social and environmental problems related to product material. The rich mineral resources in the Democratic Republic of Congo (DRC) have fueled one of the world¡¦s deadliest conflicts. Our suppliers do not have a direct purchasing relationship with mining companies. However, Xmultiple has taken positive steps to on this complex issue to assure the suppliers are not receiving minerals from the DRC.

Configuration - Arrangement of contacts in a multiple contact connector.

Connector - A mechanical device, either a plug or a receptacle, used to terminate or connect electrical conductors (pin and socket contacts) of a cable and its individual wires and provide a means to continue or terminate these conductors to a mating connector which may be mounted on electrical equipment panels, bulkheads, printed circuit boards, etc. Connectors are a type of device that provide, rapid connect/disconnect service, for wires, cables, and fibers. RJ Connectors With and Without Magnetics.

Contact Pin or socket ¡V The conductive element of a connector which actually makes contact for the purpose of conducting electrical current. This is the heart of the connector.

Contact Pin Layout for USB Connectors - The term Pinout used In electronics is a cross-reference between the contacts, or pins, of an electrical connector, and their functions.

Contact Arrangement - The number of contacts, their size and spacing in a pattern.

Contact Pin Plating - The contact pins are plated with gold, and other metals. This plating provides a better conductive metal connection and improves the performance of connectors. Contact Pin Plating for RJ Connectors.

Contact Wipe - The length of travel made by one contact in contact with another during the mating or un-mating of a connector.

Contract Manufacturer - A contract manufacturer ("CM") is a manufacturer that contracts with a firm for components or products. It is a form of outsourcing.

Corrosion - Slow degradation of materials by chemical agents and/or electrochemical reactions; rust is the most common.

Cost Structure Survey - Cost structures are simply the identification of how costs associated with the production of a good or service are distributed throughout the process. While some think of a cost structure as referring only to the finances utilized in the production process, a true cost structure will also take into consideration the use of all types of resources along the way. This can include costs such as labor and utilities, as well as back end costs like sales and marketing expenses.

Creepage Path - Path that electricity must follow across a dielectric to bridge cross two conductors; longer creepage paths reduce the likelihood of arc damage or tracking. Electricity travels along the path of least resistance. Determining the best path for electricity involves a means of measuring the distance from one conductor to another conductor. The shortest distance is through air (Air Gap) or along the surface of the insulation (Creepage Distance).

Crimp Barrel - The cylindrical portion of a terminal, splice or contact accommodating the conductor or conductors.

Crimp Contact - A contact, pin or socket, whose back portion (wire barrel) is a hollow cylinder into which a stripped wire (conductor) is inserted. The sidewalls of the wire barrel are then mechanically compressed (uniformly deformed) using a crimping tool to captivate the conductor.
