Overview
The Würth Elektronik 7447779006 is a high-performance shielded drum core inductor designed for demanding power management applications. Its primary function is energy storage in switching power supplies, critical for maintaining stable output voltage. A key design consideration is the trade-off between inductance value and DC resistance (DCR); achieving a low 35mΩ DCR while maintaining a 6.8µH inductance requires careful wire gauge selection and winding techniques, which can impact saturation current capabilities if not properly managed.
Key Features
- Inductance: 6.8 µH (±20%)
- Current Rating: 2.91 A
- DC Resistance (DCR): 35 mΩ Max
- Shielding: Shielded
- Operating Temperature: -40°C to 125°C
- Dimensions: 7.30mm x 7.30mm x 4.50mm (L x W x H)
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 converter output filtering for voltage regulation
- Energy storage in DC-DC converters for portable electronics
- Input filtering for noise suppression in sensitive circuits
