Mansfield, Texas, USA – June 9, 2010 – Mouser Electronics, Inc., known for its rapid introduction of the newest products, today announced it is the only distributor to be stocking Littelfuse Silicon Protection Array (SPA™) Sample Kits.

Modern chipsets utilize nanometer processing technologies making them extremely susceptible to damage which necessitates the need for external protection. Silicon Protection Arrays™ (SPA) are specifically designed to protect sensitive electronic components from ESD (Electrostatic Discharge), EFT (Electrical Fast Transients), and lightning induced transients. The Littelfuse SPA devices offer the lowest dynamic resistance during an ESD or any EOS (Electrical Over Stress) event which reduces clamping voltage levels far below that of competing technologies such as MLV, MOV, and polymer. The SPA portfolio offers a wide range of devices to suit the majority of applications available in the market today such as: USB 2.0/3.0, HDMI 1.3/1.4, DVI, 10/100/1000Mbps Ethernet, eSATA, 1394a/b, LVDS, audio, analog video, keypads/pushbuttons, and LCD/camera display interfaces.

Mouser is exclusively offering the SPA Sample Kits that include ten samples each of the 39 SPA devices. Additionally, each flexible notebook includes a product selection guide and protection samples of 16 different common applications. Ultimately, the sample kit provides a cost-effective supply of various SPA devices for the convenience of design engineers.

Andy Kerr, Mouser Vice President of Passives & Circuit Protection, says the new SPA devices will solve numerous issues presented by today’s ICs that have contact discharge levels down to ±0.5kV. Kerr says, “The Littelfuse Silicon Protection Arrays are an ideal solution for new ICs facing the threat of ESD damage. In addition, the SPA kits offered by Mouser will provide a cost-effective SPA supply and documentation for many suitable applications.”

“The Littelfuse line of Silicon Protection Arrays clearly delivers superior protection for today’s demanding electronic applications.” adds Paul Dickinson, Littelfuse Vice President & General Manager of the Semiconductor Products Business. “We are proud to partner with Mouser to offer devices that will address these challenging circuit protection issues for design engineers.”
