Performance Specifications


	Resistance Range		The device's resistance range.
	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.

	Tolerance		Resistance tolerance is usually expressed a percentage.
	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.

	Temperature Coefficient (TCR)		Temperature coefficient of resistance (TCR) measures the rate at which the nominal resistance changes as a function of temperature. TCR is expressed in parts per million (ppm) per degree Celsius (C), or ppm/C.
	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.

	No. of Tap Positions		For a digital potentiometer, this is the number of steps (taps) which cover the total resistance.
	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 DC Voltage		The device's maximum operating direct-current (DC) voltage.
	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 Rating		The device's maximum operating current.
	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.

	Number of Resistors		The total number of resistors in the package.
	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		This is the full-required range of ambient operating temperature.
	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 Features


	Standard and Compliances
	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.
	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.
	CSA		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.
	IEC		The International Electro technical Commission (IEC) is a global, non-profit organization that develops and maintains voluntary quality, safety, and performance standards for electrical materials, products, and systems The IEC also publishes standards for the electronics and telecommunications industries. The IEC’s membership consists of the electro technical standards organizations from each of its 51 member nations. The American National Standards Institute (ANSI) represents the United States.
	WEEE Compliant		Waste Electrical and Electronics Equipment (WEEE) 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.
	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.

	Features
	Your choices are...
	Military Standards		Devices comply with U.S. military standards.
	Water Cooled		The device is water-cooled.
	Non-Flame Coating		The device has a coating which provides protection against flames.
	Fireproof Case		The device is fireproof.
	Electrically Isolated Case		The device is covered by an electrically-isolated case.
	ESD Protection		The device is protected against electrostatic discharge (ESD).
	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.
