Compact noise suppression filter for audio wired lines
TDK launched audio line specific ferrite-based noise suppression filters to improve sound quality in portable person devices with audio input and output.
The new MAF1005FR series, measuring 1.0 mm (L) x 0.5 mm (W) x 0.5 mm (H) feature Impedance of up to 2600 Ω at 900 MHz and insertion loss of more than 25 Db; wide operating temperature range of -55 °C to +125 °C. Here are more details shared by TDK: These multilayer chip components are designed to improve sound quality and reduce noise interference in the audio lines (sound lines) of smartphones and other devices such as tablets, wearables, and portable games. Mass production of the product series began this month, November 2023. The audio lines in smartphones and similar devices emit electromagnetic noise, which can interfere with built-in antennas and degrade reception quality. This noise can be problematic, especially when high-quality audio and effective noise suppression are required. Chip beads are commonly used to control noise in audio lines. However, although they effectively reduce noise, they can also distort the audio quality, impacting the sound in these lines. The new MAF1005FR series of noise suppression filters can improve sound quality and reduce noise interference, with a typical impedance of up to 2600 Ω at 900 MHz and ...
