Products/Services for Filter Passive
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
Passive filters are implemented using only passive components such as resistors, capacitors and inductors. These filters do not produce any amplification of the input signal. Learn More about Passive Filters
IC electronic filters are frequency-selective circuits that consist of devices such resistors, capacitors, inductors, transistors, or operational amplifiers coupled with reactive components. Search by Specification | Learn More about IC Electronic Filters
Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI. Search by Specification | Learn More about EMI Filters and RFI Filters
...filters or line/load reactors. There are two choices for filter type: passive and active. Passive harmonic filters are built with a series of passive components such as resistors, inductors and capacitors. These devices are the most common type... Search by Specification | Learn More about Harmonic Filters
Signal filters block or decrease (attenuate) unwanted frequencies or signal wave characteristics. Search by Specification | Learn More about Signal Filters
RF band pass filters are active or passive circuits that pass signals from a specific frequency band and reject signals from out-of-band frequencies. Surface acoustic wave (SAW) filters, crystal filters, and cavity filters Search by Specification | Learn More about RF Band Pass Filters
RF high pass filters pass signals from high frequencies and reject signals from low frequencies. Search by Specification | Learn More about RF High Pass Filters
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
Optical bandpass filters are designed to transmit a specific waveband. They are composed of many thin layers of dielectric materials, which have differing refractive indices to produce constructive and destructive interference Search by Specification | Learn More about Optical Bandpass Filters
RF low pass filters pass signals from low frequencies and reject signals from high frequencies. Search by Specification | Learn More about RF Low Pass Filters
Display filters and films are designed to filter, enhanced and/or protect monitors or flat panel displays (FPD). Search by Specification | Learn More about Display Filters and Films
Filter wheels hold and position multiple filters for various imaging applications such as machine vision and spectrophotometry. Search by Specification | Learn More about Filter Wheels
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
Industrial air filters reduce the number of particles in the air that passes through them. Search by Specification | Learn More about Industrial Air Filters
