MITSVmi 0.8mm Pitch Board Connectors CPM-C81, C90

Category: Connectors, Electronics, Mitsumi Electric Company Ltd

The datasheet presents the MITSVmi 0.8mm pitch board connectors, specifically the CPM-C81 and C90 series. These connectors are industry-standard board-to-board interfaces, primarily utilized in interfacing with the thin CD-ROM drives found in notebook computers. The C81 series offers an angle type pin connector while the C90 series provides a straight type socket connector.

Key Features

One prominent feature of these connectors is the proprietary 350-pin board-to-board connector design. This design includes a guide mechanism which aids in preventing slipping during the connection process. Another significant feature is the use of a Liquid Crystal Polymer (LCP) for the connector, which ensures excellent dimensional stability. To underscore the reliability of the connection, the socket connector is engineered with an improved connection stability design.

Ordering Information

For ordering, a systematic approach is outlined that includes the series number (CPM-C81 or CPM-C90), the number of contacts (e.g., C81-050-2951A or C90-050-2999A), and a unique running number assigned by the manufacturer.

Electrical Specifications

The electrical characteristics of these connectors include a rated voltage of 200V AC for the pin connector, with a rated current of 0.54A (also for the pin connector). They can withstand voltages up to 500V AC (rms) for 1 minute. The insulation resistance is specified as a minimum of 500MΩ at 500mV DC, and the contact resistance is given as a maximum of 90mΩ.

Connector Types:

Pin side: Angle type (C81)
Socket side: Straight type (C90)
