General Characteristics
   Filter Type       
   Your choices are...         
   Low Pass       Low pass filters attenuate frequencies below a particular frequency called the cut-off frequency. Frequencies below the cut-off frequency pass easily through the filter 
   High Pass       High pass filters attenuate frequencies above a particular frequency called the cut-off frequency. Frequencies higher than the cut-off frequency pass easily through the filter. 
   Band Pass       Bandpass filters are used to attenuate frequencies above and below a range of frequencies called the bandwidth or passband of the filter. Any signal with a frequency within the bandpass range passes through the filter. Any signal with a frequency outside the bandpass is reduced. 
   Band Reject       Band reject filters (band stop filters, notch filters) are used to attenuate a range of frequencies and allow all other frequencies to pass. 
   Universal / Programmable       Universal filters can be configured by the user to function as a low pass, high pass, band pass, or band stop filter. 
   Other       Other unlisted filter types.

   Filter Characteristic       
   Your choices are...         
   Bessel       Bessel filters are active filters with a passband that maximizes the group delay at zero frequency, thus showing a constant group delay in the passband. Group delay is a measurement of the time it takes for a signal to move between two points in a network. A constant group delay in the passband of filters implies that for all signals with frequencies in the passband, the time delay will be the same. This fact is important in many applications, especially audio, video and radar applications. 
   Butterworth       Butterworth filters are designed so that the frequency response is flat in the passband. 
   Chebyshev       Chebyshev filters feature a very steep roll-off, but have ripples in the passband. 
   Elliptic       Elliptic filters (Cauer filters) exhibit equalized ripple in both the passband and the stopband. 
   Other       Other unlisted filter characteristics.

Standards and Certifications
   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.
   ELV Directive       End of Life Vehicles (ELV) Directive required that certain automotive products be free (except for trace impurities) of mercury, cadmium and lead by July 1, 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.
   Other       Other unlisted, specialized, or proprietary standard or certifications. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
