Overview
The Coilcraft DO3316P-333MLB is a wirewound, unshielded ferrite power inductor designed for efficient energy storage in DC-DC converter circuits. Its primary function is to smooth current ripple and store magnetic energy, with a critical operational characteristic being its inductance value of 33 µH. A key design consideration for this component, as with many unshielded inductors, is the potential for electromagnetic interference (EMI) radiation, necessitating careful PCB layout and shielding strategies in sensitive applications to mitigate unwanted emissions and maintain signal integrity.
Key Features
- Inductance: 33 µH
- Tolerance: ±20%
- Maximum DC Current: 2.1 A
- Saturation Current: 2 A
- Maximum DC Resistance: 100 mOhms
- Dimensions: 9.4 mm x 5.21 mm x 12.95 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.
- Switching regulator output filtering
- Input ripple current reduction in power supplies
- Energy storage for buck and boost converters
- Noise suppression in DC power rails
