SunlordMultilayer Chip Audio Bead(for audio lines)

Overview

The MZAH / MZAS series is a new EMC device developed for audio lines with low THD + N total harmonic distortion. Size 1005 and 1608, MZAS1608 series with filter band 100-400MHz, are mainly used to suppress Class D amplifier switching noise. MZAH series with filter band 700MHz-2GHz, are used in the headset lineto suppress the radio frequency interference signal.

Background

Smart phones equipped with 2G / 3G / LTE wireless LAN, Bluetooth and other wireless communications capabilities. For consumers, the versatility makes smart phones more and more popular. But the circuit noiseproblemcaused by a number of wireless communication functions is more and more serious. And for the sound source of the smart phone, it requires excellent audio quality, so MZAH / MZAS series of audio beads came into being. This type of audio filter beads achieve a small size, rated current over 1A high saturation characteristics

Features

  • High impedance at high frequencies
  • Low DCR,higher current
  • Excellent performance of THD+N

Applications

  • Headphones, speakers and other audio
