Overview
The Murata Power Solutions 50503AC is a surface-mount common mode choke belonging to the 5000A series. It features an inductance of 51 µH at 100 kHz and supports a maximum DC current rating of 800 mA. The component has a maximum DC resistance of 168 mΩ and operates within a temperature range of -40°C to 125°C. Designed for two-line applications, it utilizes a surface mount toroid structure.
Feature Summary
- Provides common mode noise suppression for two-line circuits
- Utilizes a surface mount toroid construction for compact integration
- Operates reliably across an extended industrial temperature range
Applications
- Signal line filtering in electronic equipment
- Noise suppression in data transmission interfaces
- EMI reduction in industrial control systems
Procurement Notes
Verify the specific package dimensions and pin configuration against the official datasheet before integration. Confirm that the 800 mA current rating meets the circuit requirements under all operating conditions. Ensure the 168 mΩ DC resistance aligns with system loss constraints. Check for any recent lifecycle status updates or alternative sourcing options.
Selection Notes
Select this component when a low-profile surface mount solution is required for two-line common mode noise attenuation. The 51 µH inductance value is suitable for standard frequency filtering applications. Consider the 800 mA current handling capability and the -40°C to 125°C operating range for environmental suitability. Evaluate the physical footprint compatibility with the target PCB layout.
Part Context
This component is part of Murata's 5000A series of common mode chokes. These components are designed for surface mount assembly and provide effective electromagnetic interference suppression. The series offers various inductance values and current ratings to suit different signal integrity requirements in modern electronic designs.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitute part numbers. Ensure any replacement maintains equivalent inductance, current rating, and physical dimensions.
