Overview
The Eaton DR74-220-R is a shielded, wirewound drum core inductor designed for robust energy storage and filtering applications. Its primary function is to store magnetic energy and release it to smooth out current fluctuations, a critical role in power conversion circuits. A key design consideration for this component is managing the trade-off between inductance value and DC resistance (DCR); while the 22 µH inductance is essential for effective filtering, the 92.5 mΩ DCR can contribute to power dissipation, necessitating careful thermal management in high-current designs.
Key Features
- Inductance: 22 µH ±20%
- Current Rating: 1.75 A
- DC Resistance (DCR): 92.5 mΩ
- Current – Saturation (Isat): 2.13 A
- Shielding: Shielded
- Dimensions: 7.60mm x 7.60mm x 4.35mm (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.
- DC-DC converter output filtering
- Power sequencing for high-speed digital logic
- EMI suppression in switching power supplies
- Energy storage in buck/boost converter stages
