Overview
The TDK ACM3225-800-2P-T is a surface mount common mode choke designed for signal lines. It features a two-line configuration with an impedance of 80 Ohms at 100 MHz and a maximum DC resistance of 150 mOhm. The component supports a rated current of 400 mA and operates within a temperature range of -25°C to 85°C. Housed in a 1210 (3225 metric) package with four terminals, it utilizes a molded structure for compact integration into electronic circuits.
Feature Summary
- Provides common mode noise suppression for signal lines through dual-line filtering architecture
- Utilizes a molded construction to ensure mechanical stability and consistent electromagnetic performance
- Designed for surface mount assembly to facilitate automated manufacturing processes
Applications
- Signal line noise suppression in portable electronic devices
- Electromagnetic interference filtering in battery charger circuits
- Noise reduction in power supply output stages
Procurement Notes
Verify the specific suffix against official TDK documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with existing footprint designs by checking terminal dimensions. Confirm availability status directly with authorized distributors as lead times may vary. Validate that the selected variant meets all required environmental operating conditions for the target application.
Selection Notes
Select this component when designing circuits requiring common mode noise attenuation for high-speed signal lines. Evaluate the 400 mA current rating against peak operational loads to prevent saturation. Consider the 150 mOhm DC resistance impact on signal integrity and power loss. Verify that the 1210 package size fits within the available board real estate constraints.
Part Context
This component belongs to the ACM series of common mode chokes manufactured by TDK Corporation. The series offers various impedance values and current ratings tailored for different signal processing needs. These components are engineered to meet industry standards for electromagnetic compatibility in consumer electronics and industrial equipment applications.
Replacement Considerations
Check for ACM3225-800-2P-T001 as a potential equivalent part number variant. Verify pinout compatibility and physical dimensions before substitution. Ensure impedance characteristics match the original design requirements.
