USB Connector provides EMI and ESD protection.
January 29, 2008 -
Designed to free-up PCB space for other components, USB connectors incorporate EMI or ESD filters into industry-standard USB package. They act as drop-in replacements for unfiltered connectors, are offered in various models that meet requirements of USB 2.0 and USB On-The-Go (OTG) specifications, and all are RoHS compliant. EMI filtered and ESD protected USB connectors have working voltage of 5 Vdc.

New USB Connector Provides EMI & ESD Protection
Fairview, PA - January 24, 2008 - Spectrum Control has developed a series of USB connectors that incorporate EMI or ESD filters into an industry standard USB package. These connectors satisfy the requirements of the USB 2.0 spec, which calls for EMI and ESD protection according to industry specifications. This protection has become more of a challenge as less space is available for components and smaller IC chips are more susceptible to low-level damage. Spectrum has moved the EMI filtering or ESD protection to the USB connector allowing designers to free-up valuable PC board space for other components and provide better protection for the entire device.
Inherent in the development of more plug-and-play devices with hot-plug capability is greater risk of system exposure to electromagnetic interference (EMI) and electrostatic discharge (ESD). Spectrum connectors are drop-in replacements for unfiltered connectors making them ideal solutions for the ongoing miniaturization of peripheral devices. These EMI filtered and ESD protected USB connectors also can eliminate the need to redesign PC boards in the event of noncompliance during either EMC or ESD testing. Various models of these connectors meet the requirements of USB 2.0 and USB On-The-Go (OTG) specifications and all are RoHS compliant.
Spectrum Control's EMI filtered and ESD protected USB connectors have a working voltage of 5VDC with a current rating of 1 Amp max and a contact resistance of 30 mW(TM) max. The EMI filtered USB connectors are available with either a capacitive filter for USB 1.1 or with an inductive filter for USB 2.0. As system circuitry has gotten more complex to accommodate faster transfer speeds and smaller package sizes, greater potential exists for damaging EMI and ESD occurrences. Spectrum's USB filtered connectors provide the needed protection in these limited spaces, which makes them ideal for EMI/RFI sensitive electronics, test and measurement equipment, notebook computers & multimedia, industrial controls and data acquisition.
Spectrum Control's USB EMI filtered and ESD protected connectors have pricing ranging from $1.00 to $3.00 depending on quantities required.
