Overview
The EPCOS B82472G4224M000 is a shielded wirewound drum core inductor designed for robust filtering and energy storage applications. Its primary function is to store magnetic energy and oppose changes in current, crucial for stable power delivery. A key design consideration for this component is the trade-off between inductance value (220 µH) and its saturation current (300 mA), where achieving higher inductance often necessitates a larger core or finer wire, potentially increasing DC resistance (1.1 Ω max) and impacting efficiency. This component’s shielded construction minimizes electromagnetic interference (EMI), making it suitable for noise-sensitive circuits.
Key Features
- Inductance: 220 µH ±20%
- Rated Current: 400 mA
- Saturation Current (Isat): 300 mA
- DC Resistance (DCR): 1.1 Ω Max
- Shielding: Shielded
- Dimensions: 7.30mm x 7.30mm x 3.50mm (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.
- EMI suppression in switching power supply output stages
- Energy storage in DC-DC converter circuits
- Filtering of ripple current in audio amplifier power rails
- Inductive sensing in proximity detection systems
