Active band pass filters are used to attenuate frequencies below and above a range of frequencies (i.e., the bandwidth or passband of the filter). Learn More about Active Band Pass Filters

RF filters and microwave filters are devices that pass or reject signals by frequency. Basic types include bandpass filters, band reject filters, low pass filters, and high pass filters. Search by Specification | Learn More about RF Filters and Microwave Filters

Long pass filters transmit a wide spectral band of long wavelength radiation while blocking short wavelength radiation. Short pass filters transmit a wide spectral band of short wavelength radiation and block long wave radiation. Search by Specification | Learn More about Long Pass Filters and Short Pass Filters

...of specific hazardous substances. End of Life Vehicles (ELV) is a similar directive, but for automotive products. There are five basic types of active filters: low pass, high pass, band pass, band reject, and universal or programmable. Low pass... Search by Specification | Learn More about Active Filters

...pass filters block or attenuate signals at frequencies above a specified cutoff frequency. Conversely, high pass filters block or attenuate signals at frequencies below a specified cutoff frequency. Band pass filters block or attenuate signals...

RF band reject filters are tuned circuits that prevent the passage of signals within a specified band of frequencies. These devices are also known as bandstop or notch filters. Search by Specification | Learn More about RF Band Reject Filters

...high-frequency signals and conduct low-frequency signals. By contrast, capacitors block low-frequency signals and conduct high-frequency signals. There are many types of passive filters, but basic categories include low pass, high pass, band pass... Learn More about Passive Filters

...in the transmitted light. In this way optical bandpass filters can be designed to transmit a specific waveband only. Optical bandpass filters are designed to pass only a specific wavelength range. The range limitations are usually dependant upon... Search by Specification | Learn More about Optical Bandpass Filters
