EMI Filters and RFI Filters - (251 companies)
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

Filter Type: Single Phase | Three Phase | DC | Other

Package / Mounting: Module | Stand Alone | Desktop | Bulkhead Mount

Rated Voltage: | | |

Optical Bandpass Filters - (74 companies)
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 in the transmitted light Search by Specification | Learn more about Optical Bandpass Filters

Neutral Density Filters - (65 companies)
Neutral density filters are designed to reduce transmission evenly across a portion of the spectrum. They are slightly sensitive to angles but they are much more forgiving than interference filters Search by Specification | Learn more about Neutral Density Filters

Power Filters - (93 companies)
Power filters are electronic circuits designed to locate and eliminate surges, harmonic transient currents, spikes, and other unwanted signals in power distribution systems and electrical equipment such as computers, television sets, and other devices Learn more about Power Filters

LVDT and RVDT Signal Conditioners - (56 companies)
Linear variable differential transformer (LVDT) and rotary variable differential transformer (RVDT) signal conditioners are devices that translate the linear or rotary movement of a ferromagnetic armature into an AC voltage that is proportional to the armature position Search by Specification | Learn more about LVDT and RVDT Signal Conditioners

Resistors - (749 companies)
Resistors are electrical components that oppose the flow of either direct or alternating current. They are used to protect, operate, or control circuits. Search by Specification | Learn more about Resistors

Resistors and Potentiometers - (789 companies)
Resistors and potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC). Search by Specification | Learn more about Resistors and Potentiometers

Film Capacitors - (116 companies)
Film capacitors are insulated with polyester, polycarbonate, polypropylene, polystyrene, or other dielectric materials. Search by Specification | Learn more about Film Capacitors

Water Quality Testing Instruments - (219 companies)
Water quality testing instruments are used to test water for chemical and biological agents, and to measure variables such as clarity and rate of movement Search by Specification | Learn more about Water Quality Testing Instruments

DC Servomotors - (314 companies)
DC servomotors are generally small and powerful for their size, and easy to control. Common types of DC servomotors include brushless or gear motors. Search by Specification | Learn more about DC Servomotors

Fiber Bragg Gratings - (12 companies)
Fiber bragg gratings have a periodically altered refractive index to filter certain wavelengths while allowing others to pass Learn more about Fiber Bragg Gratings

Industrial Dehumidifiers - (91 companies)
Industrial dehumidifiers remove excess moisture from the air in order to prevent rust, mildew, and damage to electrical components. Search by Specification | Learn more about Industrial Dehumidifiers

Boiler Controllers - (53 companies)
Boiler controllers monitor and maintain variables such as steam temperature and pressure in order to control a boiler’s burner or air mixture Learn more about Boiler Controllers

Brake Controllers - (20 companies)
Brake controllers are used to control braking systems. They can simply engage and disengage the brake, or control the speed of engagement, breakaway torque, and other variables Learn more about Brake Controllers

Laboratory Fume Hoods - (170 companies)
Laboratory fume hoods are partially enclosed workspaces that are exhausted to the outside. Search by Specification | Learn more about Laboratory Fume Hoods
