Spectrum Control offers a full line of ESD/EFT (electrostatic discharge/electronically fast transients) protected connectors and adapters for sensitive circuit applications.
According to the manfacturer, the Series E connectors are capable of providing ESD/EFT and EMI protection all in one package, removing ground traces from the board and offering protection at the I/O ports and to all lines. The metallic front shell also provides low ground impedance. These connectors free-up valuable real estate by reducing the number of components necessary to protect circuits from ESD/EFT/EMI. In turn, this component reduction yields savings related to the total cost of purchasing, stocking, placing and testing other additional components.
The Series E connectors integrate transient voltage suppressors from Littelfuse, and are available in industry standard size footprints of 0,318", 0,405", and 0,590" (8,1, 10,3 and 15,0 mm) and may be used as drop-in replacements for unprotected connectors. A wide range of clamping voltages and capacitance levels are featured to fit specific applications.
Connectors are available with (up to 2200 pF) or without capacitance values. Connectors with capacitance values less than 0,5 pF are for use in digital or extremely high-speed signal lines. Maximum working voltage ratings range from 3,5 to 30 V d.c. and 2,5 to 25 V a.c. Shell sizes 9, 15, 25 and 37 are offered in a variety of contact types/terminations and mounting or hardware options.
