Overview
The Coilcraft DO3316P-473MLD is a wirewound ferrite power inductor designed for efficient energy storage in DC-DC converter circuits. Its critical operational characteristic lies in its inductance value of 47 µH, which dictates the energy buffering capability. A key design consideration for this unshielded component is the trade-off between its relatively high saturation current of 1.6 A and its potential for EMI radiation, necessitating careful layout and shielding strategies in noise-sensitive applications to maintain signal integrity.
Key Features
- Inductance: 47 µH
- Tolerance: ±20%
- Maximum DC Current (IDC max): 1.8 A
- Maximum DC Resistance (DCR): 140 mΩ
- Saturation Current (Isat): 1.6 A
- Dimensions: 12.95 mm (L) x 9.4 mm (W) x 5.21 mm (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/Boost converter output filtering
- Power sequencing for embedded systems
- Input filtering for noise reduction in switching power supplies
- Energy storage in portable device power management ICs
