Below is a technical write-up covering its specifications, applications, electrical characteristics, and design considerations. 1. Overview The ACM1552U-Z2 is a common-mode choke designed for high-speed differential signal lines. It is part of TDK’s ACM series, which targets USB, HDMI, LVDS, MIPI, and other high-speed interfaces. The component suppresses common-mode noise while preserving differential signal integrity.
Its key feature is a of common-mode noise without distorting high-speed data waveforms. 2. Package & Construction | Parameter | Details | |-------------------|--------------------------------| | Package type | 0504 (metric) / 1.6 × 1.0 mm (approx.) | | Height | 0.5 mm typical | | Termination | Gold-plated (or tin) for reflow soldering | | Construction | Multilayer ferrite with internal coupled windings | | RoHS | Yes | | AEC-Q200 | No (general-purpose, not automotive grade) | Note: “1552U” likely denotes the product series impedance characteristics, while “Z2” indicates packaging/reel configuration (e.g., 2 mm pitch tape). 3. Electrical Specifications (Typical from ACM family) | Parameter | Value / Range | |-------------------------------|------------------------| | Impedance at 100 MHz (common mode) | 90 Ω ±25% | | DC resistance (Rdc) per line | ≤ 2 Ω | | Rated current (Ir) | 100 mA to 150 mA | | Rated voltage | 10 V DC | | Insulation resistance (IR) | ≥ 10 MΩ | | Temperature range (operating) | -40°C to +85°C | acm1552u-z2
The ACM1552U-Z2 wins for when current is below 150 mA. 9. Ordering & Marking Full ordering code example: ACM1552U-900-Z2 Below is a technical write-up covering its specifications,
Marking on part: Usually none (too small) or a single letter code for impedance. It is part of TDK’s ACM series, which
