| Description & Applications | FEATURES A single ACA series chip can be used to suppress noise on 3, 4, or 6 lines, depending on the selected part. This product is thus an excellent choice for EMC suppression at the I/O lines of compact electronic equipment, such as portables, which require high-density circuit configurations. Two types are available: the M type for general signals and the H type for high-speed (high-frequency band) signals. This noise countermeasure is therefore applicable to various types of circuits. A 3-line type is available specifically for audio applications, such as headphone lines. A 4-line type with a 3216 form factor is available as a direct replacement for standard chip resistor arrays. It can be used without any change to the circuit board land pattern. APPLICATIONS Noise suppression for audio applications, including headphone lines in CD-ROM, DVD, MD, and other equipment (3-line type). Noise suppression for the I/O lines of notebook PCs, word processors, digital TVs and VTRs, and portable communications equipment. |
