In order to properly limit EMI (Electromagnetic Interference) and enhance EMS, noise management technology focusing on EMC (Electromagnetic Compatibility) is crucial (Electro Magnetic Susceptibility).
An inductor is a variety of shapes and sizes of electro-magnetic components with the property of inductance. Insulated wire conductors are often coiled into a coil and placed around a ferromagnetic core material, such as iron, to create a conventional inductor.
As filters that can balance noise suppression and audio quality, inductors for audio line noise suppression were created.
The Global Inductor For Audio Line Suppression Market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
TDK VAF-FA Inductors have high damping capabilities and low resistance values, making them ideal Class-D noise suppression filters for audio lines. These inductors have a low-distortion ferrite structure and can function between -40 and 105 °C.
The maximum DC current range for the TDK SMT inductor series is 2.14A to 3.08A, and its dimensions are 2mm x 1.6mm x 1mm (LxWxH). High current audio lines, AI speakers, high-fidelity speakers, Bluetooth speakers, and TV speakers all benefit from VAF-FA inductors.
The LQW CA Series of inductors from Murata were created as filters that could strike a compromise between noise reduction and audio quality.
Due to electromagnetic noise from communication frequency bands’ impacts on the audio line, the widespread use of smartphones has led to the issue of decreased audio quality. In response, Murata created a new line of inductors with good Z characteristics in the communication frequency ranges that are 0402-size (1.0mm 0.5mm) (700MHz to 2,700MHz bands).
To reduce audio line noise, Murata Manufacturing Co., Ltd. announced inductors. As filters that can balance noise suppression and audio quality, the LQW CA Series of inductors for audio line noise suppression was created.
Smartphones and other mobile phones are made to decrease electromagnetic noise from communication frequency bands (approx. 700MHz to 2,700MHz). Inductors of the winding kind offer high rated current and low DC resistance.
A 10-W/ch, high-efficiency, low-idle-current Class-D stereo audio amplifier from TI is the TPA3138D2. It can operate stereo speakers with a 3.2- load. Longer audio playback and improved thermal performance in bluetooth speakers, battery-operated appliances, and other power-sensitive applications are made possible by the 1SPW mode’s low idle current consumption of just 21 mA (12 V) and ability to run down to 3.5 V.
With advanced EMI suppression and spread spectrum control, system costs can be reduced by using low-cost ferrite bead filters while still meeting EMC standards.
The new 1210-size automotive-grade common-mode chip inductor series from Bourns, Inc. The most recent line of common-mode inductors from Bourns is bifilar coiled with a ferrite core for a small overall size and shielded construction.
The Model SRF3225AB and SRF3225TAC common-mode chip inductor series are excellent choices for design-in and testing in consumer, industrial, and many other electronics applications because they provide low radiation and high impedance over a wide frequency range to suppress Electromagnetic Interference (EMI) entering or leaving the system.
For noise suppression in 2-wire UTP (unshielded twisted pair) cable vehicle audio bus systems, the Model SRF3225AB was created specifically.
