Overview
The Würth Elektronik 744777122 is a shielded, wirewound drum core inductor designed for demanding power management applications. Its primary function is to store and release energy in DC-DC converter circuits, smoothing current ripple and ensuring stable voltage regulation. A critical design consideration for this component is the trade-off between its high inductance (22 µH) and its DC resistance (110 mΩ max). While high inductance is beneficial for filtering, a lower DCR is crucial to minimize power loss and thermal dissipation, especially at higher current loads of 1.41 A, preventing efficiency degradation and ensuring component longevity.
Key Features
- Inductance: 22 µH (±20%)
- Current Rating: 1.41 A
- DC Resistance (DCR): 110 mΩ Max
- Shielding: Shielded
- Core Material: Manganese Zinc Ferrite (MnZn)
- 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 mobile power supplies
- Energy storage in automotive power management modules
- Ripple current reduction in LED driver circuits
- Inductive element in switch-mode power supply (SMPS) designs
