Product Overview

The ACM2520-301-2P-T002 is a chip-type common-mode filter for high-speed differential signal lines by TDK, designed to suppress common-mode noise in high-speed signal transmission. Using a wound structure for significant miniaturization, it combines efficient noise suppression with low differential-mode impedance, suitable for high-speed interface cables like USB, IEEE1394, and ETHERNET. Compliant with RoHS and halogen-free standards, it offers a reliable EMC solution for high-density PCBs.

Key Features

• Effective Common-Mode Noise Suppression: Achieves a typical common-mode impedance of 300Ω at 100MHz, efficiently filtering common-mode interference in high-speed signal lines to ensure pure signal transmission.
• Minimal Differential-Mode Impact: Differential-mode impedance is suppressed to an extremely low level, causing negligible loss to high-speed signals like USB and LVDS, maintaining signal integrity.
• Ultra-Compact Design: Measures only 2.5×2.0×1.2mm, fitting high-density PCB layouts and meeting the integration needs of portable devices and compact circuits.
• Wide Temperature Range: Operates and stores between -40°C and +85°C, ensuring stable performance in harsh environments.
• Eco-Compliant Certification: RoHS and halogen-free (Cl/Br < 900ppm, total < 1500ppm), supporting the design of green electronic products.

Technical Specifications

Typical Applications

• High-Speed Interface Noise Reduction: Suitable for USB 2.0/3.0 cables, IEEE1394 data lines, and ETHERNET cables in computers and peripherals, effectively suppressing common-mode noise that interferes with high-speed data transmission to ensure stable signal flow.
• Display Signal Optimization: Used in LVDS and Panel Link differential signal lines for LCD screens, reducing image noise or transmission delay caused by common-mode interference to enhance display quality.
• Compact Circuit Integration: The ultra-small size is ideal for high-density PCBs in portable devices like smartphones, tablets, and ultrabooks, enabling efficient EMC filtering in limited spaces.
