Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 10µH inductance paired with a 300mA current ceiling makes this inductor a natural fit for low-power buck converters used in battery-operated devices.
• RF Noise Suppression: With a DCR of 1.37 Ohm, it effectively dampens high-frequency ripple without excessive copper loss, preserving signal integrity in wireless modules.
• Power Line Smoothing for IoT Sensors: The compact SMD profile and 10µH value enable steady current delivery to always-on sensing nodes where board real estate is at a premium.

Key Features & Advantages

• Precise 10µH Inductance: Delivers consistent energy storage and ripple attenuation for stable downstream voltage rails.
• 300mA Current Handling: Matched to the needs of portable and low-power electronics, ensuring reliable operation without saturation.
• Low 1.37 Ohm DCR: Minimizes I²R power loss and heat generation, extending battery life in continuous-use scenarios.
