Filters Definition

JMChip Electronics is one of the leading distributors of electrical parts and offers a wide range of filters. They carry filter accessories, EMI Filters (Electromagnetic Interference Filters), Wix Filters, Air Filters, Water Filters, Ceramic Filters, Helical Filters, RF Filters, SAW Filters, and more. Below, you'll find some explanations about filters—what they are, the various types available, and how they function.

What is Filter in Electrical?

Electronic filters are electrical circuits designed to process and filter signals. As common components in electronics, filters have many practical applications, such as in radio communications, audio equipment, DC power supplies, analog-to-digital converters, and more.

Types of Filers in Electrical

There are four main types of filters you can find on the market: high-pass filters, notch filters, low-pass filters, and band-pass filters. Below, you’ll see a list of other popular filter types, like Ferrite Beads, Power Line Filters, EMI/RFI Filters, SAW Filters, RF Filters, and more.

What are Ferrite Beads

Ferrite beads, also known as Ferrites, Ferrite Chokes, Ferrite Blocks, Ferrite Rings, or Ferrite Cores, are a type of choke used to suppress high-frequency electronic noise in circuits.

RF Filters

RF Filter, which stands for Radio Frequency Filter, is a special type of electrical circuit that lets the right signals pass through. It can either allow selected frequencies or block unwanted signals to eliminate noise. There are four types of RF filters: high-pass filters, low-pass filters, bandpass filters, and band-reject filters. RF filters are commonly used in wireless communications, TV, and broadcast radio.

SAW Filters

SAW Filter, short for Surface Acoustic Wave Filter, is a passive semiconductor component used to filter out specific frequencies. SAW Filters are widely used to filter IF and RF frequencies in mobile telecommunications, radar, medical devices, and aerospace & military communications.

Frequently Asked Questions

What is a feedthrough filter?

A feedthrough filter is the most commonly used filter for suppressing interference in the signal and power line circuits. It’s great at filtering out high-frequency interference.

What wave does the filter filter out?

A filter device is used in power transformation and distribution systems. Its main function is to filter out harmonics. When there are high requirements on the power grid, the sine wave might change in strange ways, making it hard to use.

What is a bandpass filter?

A bandpass filter acts as an electronic interface unit. It allows signals within a specific frequency range to pass through while blocking signals outside this range, achieving selective transmission.
