Gapped inductor with edge-on conductor winding, for power conversion, the two main pads are for electrical connections, the third pad (at the back) is also soldered down to a PCB, but it is used to assist with mechanical mounting.
Parameters of this inductor (after Wurth Electronic Online, 7443641500, Datasheet, {accessed 2021-08-26}):
- inductance L = 15 uH (+/- 15%)
- rated at IR = 30 A max with temperature rise of 50 K, or 34.95 A max for 40 K
- performance current IRP = 34.95 A max for 40 K
- saturation current 22 A (typical) at 10%, IΔL/LI 10%
- saturation current 26 A (typical, at 20 °C) at 30%, IΔL/LI 30%
- DC resistance 2.4 mΩ (typical at 20 °C)
- DC resistance 2.64 mΩ (max. at 20 °C)
- self-resonance frequency 11 MHz (typical)
