| |||
| Mounting / Packaging | |||
| Your choices are... | |||
| Surface Mount (SMT / SMD) | Surface mount technology (SMT) adds components to a printed circuit board (PCB) by soldering component leads or terminals to the top surface of the board. SMT devices (SMD) have a flat surface that is soldered to a flat pad on the face of the PCB. Typically, the PCB pad is coated with a paste-like formulation of solder and flux. With careful placement, SMT components on solder paste remain in position until elevated temperatures, usually from an infrared oven, melt the paste and solder the component leads to the PCB pads. | ||
| Bolt-on (Chassis) | Chassis-mounted devices bolt onto or within a structure’s supporting frame, typically in a metal-to-metal configuration for better heat dissipation. Some chassis types are designed to be mounted within a rack. | ||
| Panel Mount | Panel-mounted devices have a threaded bushing surrounding the shaft. | ||
| Through-Hole | Through-hole technology (THT) mounts components on a printed circuit board (PCB). Components leads are inserted through holes in the board and then soldered in place on the opposite side of the board. | ||
| Axial Leads | Axial leads extend from the ends and along the axis of the device. They do not extend from the sides. | ||
| Gull Wing Leads | Gull-wing leads are widely used because they are relatively inexpensive to mold and form. Gull wings are flexible and can withstand thermal expansion and contraction. It is easy to inspect the integrity of gull-wing leads to circuit-board solder connections. | ||
| J-leads | J-leads are popular because they use less PCB real estate than gull-wing leads; however, J-lead to board solder connections are hidden from inspection. The leads are also more difficult to form. | ||
| Radial Leads | Radial leads extend from the sides instead of from the ends. | ||
| Screw Terminals | Screw terminals are designed for screw mounting on a circuit board. | ||
| Tab Terminals | Terminals are designed for direct mounting on a circuit board. | ||
| Flip Chip | Flip chip is a mounting style that does not require the attachment of wires to the IC chip. | ||
| SOIC | Small outline integrated circuit (SOIC). | ||
| SSOP | Shrink small outline package (SSOP). | ||
| SC-70 | SC-70 is one of the smallest available IC packages. It is used in cellular phones, PDAs, electronic games, laptops and other portable and hand-held applications where space is extremely limited. | ||
| SOT23 | SOT23 is a rectangular, surface mounted, small outline transistor (SOT) package with three or more gull wing leads. SOT23 features a very small footprint and is optimized for the highest possible current. Because of its low cost and low profile, SOT23 is used in home appliances, office and industrial equipment, personal computers, printers, and communication equipment. | ||
| Other | Other unlisted, specialized, or proprietary configurations. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

|
|
| ||
| Supply Voltage (VS) | Supply voltage (VS) refers to the source-voltage range. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
| |||
| Trigger Voltage | This is the maximum voltage that will trigger the device. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Trigger Current | This is the maximum current that will trigger the device. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Current Surge | Current surge is the rated maximum value of the peak impulse current that the suppressor can withstand. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Response Time | Response time is the elapsed time between the triggering of the suppressor and the beginning of the response. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Operating Temperature | Junction operating temperature (Tj) is the range of temperatures over the device operates. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||

Standards and Certifications

|
|
| ||
| Your choices are... | |||
| RoHS Compliant | Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl, and polybrominated diphenyl ether. RoHS became effective on July 1, 2006. | ||
| WEEE Compliant | The Waste Electrical and Electronics Equipment (WEEE) Directive is a European Union (EU) directive designed to encourage the reuse, recycling, and recovery of electrical and electronic equipment. WEEE is also designed to improve the environmental impact and performance of this equipment. The WEEE Directive establishes requirements and criteria for the collection, treatment, recycling and recovery of electrical and electronic equipment. It also makes producers responsible for financing these activities. Retailers and distributors must provide a way for consumers to return used or obsolete equipment without charge. | ||
| ELV Directive | End-of-Life Vehicles (ELV) is a European Union (EU) directive that requires manufacturers of automotive products sold in Europe to demonstrate that their products contain only minimal levels of mercury, cadmium, and lead. Lead can still be used as an alloying additive in copper, steel, and aluminum. | ||
| UL | Underwriters Laboratories (UL) is a non-profit organization that tests components, systems, and materials according to its published standards for safety. Products that receive UL approval bear a UL Mark. | ||
| VDE | Verband Deutscher Elektrotechniker (VDE), the Association of German Electrical Engineers, is a non-profit testing institute that publishes standards and certifies electrical and electronic components. The VDE Mark indicates conformity with VDE, European Union (EU), and internationally harmonized standards. It confirms compliance with the protective requirements of the applicable EU directives. | ||
CSA Mark |
Products that bear a CSA Mark have been tested by the Canadian Standards Association (CSA) and meet applicable standards for safety and/or performance. These standards are written and administered by organizations such as the American National Standards Institute (ANSI), Underwriters Laboratories (UL), and CSA International. CSA Marks may appear alone or with indicators. CSA Marks that appear alone are used with products certified primarily for the Canadian market, to the applicable Canadian standards. CSA Marks that appear with the indicators “C” and “US” or “NRTL/C” are used with products certified for both the U.S. and Canadian markets, to the applicable U.S. and Canadian standards. | ||
VDE CECC Mark |
The VDE CECC Mark is applied to electronic components that meet CECC specifications. CECC is an acronym for the CENELEC Electronic Components Committee. | ||
| Other | Other unlisted standards. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
