Detailed Description

TDK ACF451832-331-T is an ACF series multilayer chip EMI filter array designed for noise suppression on multiple signal lines in compact electronics. The “331” code indicates the filter value code for the integrated elements within the array. This part fits designs that need stable EMI attenuation with minimal impact on signal integrity and board space. It is listed under Integrated Circuits, Specialized ICs in our catalog for easy sourcing by design engineers.

Key Features

Multiline EMI filter array for compact boards

Low added parasitic effects to preserve data integrity

Lead-free and RoHS compliant

TDK process quality and lot-to-lot consistency

Key Advantages

Saves PCB space compared with discrete filters per line

Simplifies routing and reduces component count

Improves EMC margin with consistent performance

Streamlines procurement with a single integrated filter array

Reliable quality from a top-tier manufacturer

Packaging

Type: Surface-mount device, array-style EMI filter

Material: Multilayer ceramic structure with integrated electrodes

Size code: Package 4518 (compact rectangular SMD footprint)

Case code: 1180 (refer to datasheet for exact mechanical drawing)

Pin configuration: Multiline feed-through style with common reference; verify exact pinout and ground terminal placement in the datasheet
