What are the key features of ME3220-222MLB?
- 2.2 µH nominal inductance in a compact 1211 (3.2 x 2.8 mm) case for high-density power supply designs
- Ultra-low DC resistance of 0.104 Ω minimizes conduction losses and improves efficiency in DC-DC converters
- Ferrite core construction supports high-frequency power conversion with low core losses
- Pb-free and RoHS compliant, suitable for environmentally regulated consumer and industrial products
What is ME3220-222MLB used for?
The ME3220-222MLB is designed for SMT power supply filtering, DC-DC converter output stages, and EMI suppression in consumer electronics, wearables, and IoT devices where a 2.2 µH low-loss inductor must fit within a minimal 1211 board footprint. Its low 0.104 Ω DCR makes it suitable for output filter inductors in buck converters operating at switching frequencies from several hundred kHz to a few MHz. The unshielded ferrite construction provides cost-effective inductance for non-magnetically sensitive layouts.
