Eaton HC9‑470‑R Power Inductor 47 µH 3.65 A Surface Mount Wirewound SMT 14.1×13.1×7.5 mm

The Eaton HC9-470-R is a high-current, surface-mount power inductor designed for demanding switch-mode power and DC-DC converter applications. Engineered with an iron-powder core and non-organic binder technology, this 47 µH (49.2 µH OCL) inductor combines compact form and reliability, meeting the stringent thermal and electrical requirements of modern power systems.

Crucial Features and Benefits of the Product

• Inductance: 47 µH ±15% (Open‑circuit 49.2 µH)
• Rated Current (Irms): 3.65 A continuous, ideal for high‑current paths
• Saturation Current (Isat): 5.7 A (30% roll‑off at 20 °C), reliably handles surge and ripple currents
• DC Resistance (DCR): Max 72.3 mΩ; low resistance yields minimal I²R losses
• Core & Construction: Iron‑powder core with non‑organic binder for superior thermal stability and longevity
• Operating Range: –40 °C to +155 °C (operating plus self‑temperature rise), suitable for harsh environments
• Form Factor: SMT package, compact 14.1 mm × 13.1 mm × 7.5 mm (L×W×H); tape‑and‑reel packaging, 450 units per reel
• Test Frequency: 100 kHz, aligns with common switching frequencies in power systems
