Visão Geral
Description
SPM6550T-4R7M is a surface-mount shielded power inductor in a 6.5 × 5.0 mm package designed for DC-DC converter power paths and filtering.
- Inductance: 4.7 µH (4R7) with tolerance M (±20%)
- Package: 6.5 × 5.0 mm (6550 footprint)
- Features: suitable for high-current switching regulators, low DC resistance
- Typical uses: buck/boost converters, VRMs, power-filter networks
- Note: exact ratings (Isat, Irms, DCR, temperature range) come from the datasheet—refer to it for thermal limits and environmental specs.
If you’re selecting, verify the current rating and temperature rise to ensure it meets your application requirements.
