Overview
The Wurth Elektronik 7445404 is a shielded, wirewound power choke designed for efficient energy storage in DC-DC converter circuits. Its critical operational characteristic lies in its ability to handle significant current while maintaining a stable inductance value, crucial for voltage regulation. A key design consideration for this WE-PD3 series component is the trade-off between its ferrite core’s magnetic flux density and the potential for saturation at high current levels, which can degrade performance; careful selection of operating current relative to the 4.7A saturation current is paramount for optimal efficiency and ripple reduction.
Key Features
- Inductance: 4.7 µH
- Tolerance: ±20%
- Maximum DC Current: 2.7 A
- Saturation Current: 4.7 A
- Maximum DC Resistance: 40 mΩ
- Dimensions: 12.7 mm x 10 mm x 5.2 mm
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Buck/Boost converter output filtering
- Power sequencing for embedded systems
- Noise suppression in automotive power rails
- Energy storage in battery management systems
