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 specification for EMI and ESD protection. 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.
These connectors are drop-in replacements for unfiltered connectors, making them suitable solutions for the ongoing miniaturisation of peripheral devices. They can also eliminate the need to redesign PC boards in the event of non-compliance 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.
The connectors have a working voltage of 5 V d.c. with a current rating of 1 A and a contact resistance of 30 mΩ. They are available with either a capacitive filter for USB 1.1 or with an inductive filter for USB 2.0.
