Overview
The Würth Elektronik 7448421016 is a through-hole common mode choke from the WE-CMB Power Type S series. It features an inductance of 16 µH at 100 kHz and supports a maximum DC current of 10 A. The component has a maximum DC resistance of 3 mΩ and operates within a temperature range of -40°C to +125°C. Constructed with a Nickel Zinc core, it measures 25 mm in length, 12 mm in width, and 19 mm in height, providing robust EMI suppression for power lines.
Feature Summary
- Provides effective electromagnetic interference suppression for dual-line power applications
- Utilizes a Nickel Zinc core material for stable performance under high current conditions
- Designed for through-hole mounting to ensure secure PCB integration
Applications
- Power line filtering in industrial equipment
- EMI suppression in AC/DC power supplies
- Noise reduction in automotive electronic systems
Procurement Notes
Verify the specific datasheet version to confirm mechanical dimensions and thermal characteristics. Ensure the selected component matches the required through-hole footprint and lead configuration for your PCB design. Cross-reference the manufacturer's part number with official distributor catalogs to confirm availability and compliance with relevant safety standards before finalizing procurement.
Selection Notes
Select this component when a high-current rating of 10 A is required for common mode noise suppression. The low DC resistance minimizes power loss in the circuit path. Consider the physical size constraints of the application, as the through-hole package requires specific board space. Verify that the operating temperature range meets the environmental demands of the end product.
Part Context
This component belongs to the WE-CMB Power Type S series, designed for general-purpose power line filtering. It is manufactured by Würth Elektronik, a provider of passive components and modules. The series is characterized by its ability to handle significant current loads while maintaining effective noise attenuation across a broad frequency spectrum.
Replacement Considerations
Check for direct substitutes within the same WE-CMB series that offer compatible inductance and current ratings. Ensure any replacement maintains the through-hole mounting style and similar physical dimensions to fit existing board layouts without modification.
