Filter Type




   Filter Type       
   Your choices are...
 
      
 
   Single Phase
 
     A type of alternating current (AC) with a single output that may be center tapped for dual voltage levels.
 
   Three Phase
 
     A type of alternating current (AC) with three separate outputs from a single source with a phase differential of 120 electrical degrees between any two adjacent voltages or currents.
 
   DC
 
     A direct current (DC) is one that flows always in the same direction.
 
   Other
 
     Other unlisted or proprietary filter types.
 
   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.
   Package / Mounting       
   Your choices are...
 
      
 
   Module
 
     Smaller filter package designed for inline applications.
 
   Stand Alone
 
     The EMI / RFI filter is a stand-alone package; including wall-mounted filters.
 
   Desktop
 
     Larger desktop size ideal for testing applications.
 
   Bulkhead Mount
 
     The filter has a plate (bulkhead) used to mount the device.
 
   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.
 
   Power Entry Module
 
     Power entry modules are composed of a connector and a mounting case with features to produce the highly conditioned output necessary for medical or sensitive instrumentation. These features can include EMI line-filters, on/off switches, built-in fuses and circuit breakers, RFI filters, and overload protection.
 
   Flange Mounted
 
     Flange mounted modules are attached to panels by bolting the flange or riveting it in place through the holes in the flange surface.
 
   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 Canadian)
 
     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

CE Conformity Mark

 
     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)

TUV Rheinland

 
     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.
