Board Mount EMI Filters and RFI Filters Specifications

Help with Board Mount EMI Filters and RFI Filters specifications:

Filter Type

	Package / Mounting
	Your choices are...
	Surface Mount		Surface mount technology (SMT) is an important technology that allows the use of small components that can be placed directly onto a circuit board. Using smaller components allows for higher frequencies of operation, smaller board size, etc.
	Printed Circuit Board		Printed circuit board (PCB) filters are mounted on computers or system boards.
	Feed Through		A feed through filter is mounted by inserting pins into the mounting device.
	Other		Other unlisted package or mounting type.
	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.

Filter Performance

	Rated Voltage:		The voltage for which the EMI / RFI filter was designed to operate optimally and safely.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Rated Current:		The current for which the EMI / RFI filter was designed.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Minimum Insertion Loss:		A statement of the filter's attenuation characteristics, exercising in decibels (dB) the ratio of noise that would get through without the filter, to that which gets through with the filter installed.
	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:		The temperature range the filter was designed to operate correctly.
	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.
	Approvals
	Your choices are...
	UL Recognized Component Mark (US and Canada)		These Marks are used only on component parts that are part of a larger product or system. These components may have restrictions on their performance or may be incomplete in construction. Products intended for Canada carry the Recognized Component Mark "C."
	UL Listing Mark		This Mark, denotes that Underwriters Laboratories Inc. (UL) has found that samples of the product met UL's safety requirements. These requirements are primarily based on UL's published Standards for Safety.
	CSA Mark (US, C and US, NRTL/C)		The CSA Mark may appear alone or with indicators. If it appears alone, it means that the product is certified for the Canadian market, to the applicable Canadian standards. If this Mark appears with the indicator "C and US" or "NRTL/C" it means that the product is certified for both the U.S. and Canadian markets, to the applicable U.S. and Canadian standards.
	VDE Component Mark		For electronic components that meet Verband Deutscher Electrotechniker (VDE) standards.
	MIL-SPEC		Filter meets military specifications.
	CE Conformity Marks		The CE-marking is a regulatory community sign that has to be obligatorily affixed on industrial products conforming to European Union standards. However, the CE-mark is not yet a quality mark.
	TÜV Rheinland (US, C, US & C)		TÜV Rheinland/Berlin-Brandenburg provides International Approvals Services as they relate to product safety. Products certified by TÜV Rheinland for the US market are identified by the TUVus certification mark. TÜV Rheinland of North America is also established as a Certification Organization in Canada. When the TUVus mark is coupled with the cTUV mark, the product is certified compliant for both the US and Canadian markets.
	Other		Other unlisted agency approval.
	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.

Standards and Certifications

	ELV Directive		End of Life Vehicles (ELV) Directive requires that certain automotive products be free (except for trace impurities) of mercury, cadmium and lead as of 7/01/2003. Lead can still be used as an alloying additive in copper, steel and aluminum and in solderable applications.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	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 will become effective on July 1, 2006.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	WEEE Compliant		“The Waste Electrical and Electronics Equipment Regulations (WEEE Regulations) is a European Parliament Directive with the aim of encouraging reuse, recycling and recovery of electrical and electronic equipment, and to improve the environmental impact and performance of these equipments.  This directive sets the requirements and criteria for the collection, treatment, recycling and recovery of these equipments. It makes producers responsible for financing these activities, and retailers and distributors must provide means for consumers to return used or obsolete equipments without charge.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
