✔ RoHS Compliant  /  ✔ SMD  /  ✔ TDK Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Power-Supply Filtering: The 4.7µH value combined with low 180 mΩ DCR provides clean output smoothing in DC-DC converters, minimizing ripple while maintaining high efficiency up to 600mA.
• Portable Electronics: With a compact SMD footprint and 600mA current handling, it suits battery-powered devices such as wireless sensors or wearable modules where size and power loss are critical.
• Signal Isolation: Its fixed inductance at 4.7µH makes it ideal for decoupling noise in mixed-signal circuits, such as those found in IoT end-nodes or RF transceiver paths.

Key Features & Advantages

• Low DC Resistance (180 mΩ): Reduces I²R losses, improving thermal management and overall power conversion efficiency in continuous-load designs.
• 600mA Saturation Current: Handles moderate peak currents without significant inductance roll-off, ensuring stable performance under transient load changes.
• SMD Package for Automated Assembly: Compatible with standard reflow soldering processes, enabling high-throughput production without manual handling.
