The Coilcraft DO3316P-331HC is a surface-mount power inductor from the DO3316HC series, specifically engineered for high-current, low-voltage DC-DC converter applications. This rugged design offers a 0.33 µH inductance with a tight ±20% tolerance, tested at 100 kHz.
Key electrical specifications include a low DCR of 0.002 Ohms maximum, a saturation current (Isat) of 20A, and an RMS current rating (Irms) of 16A for a 40°C rise above ambient. The inductor operates efficiently with a typical self-resonant frequency (SRF) of 200 MHz.
Designed for automated assembly, the DO3316P-331HC features a flat top for pick-and-place handling and comes in tape and reel packaging. Its operating temperature range is -40°C to +85°C, making it suitable for various environmental conditions. The tinned, self-leaded construction ensures excellent solderability and low DCR values.
This inductor is ideal for applications requiring high current handling in a compact SMT package. Its robust design and reliable performance make it a suitable choice for power supply circuits and other demanding electronic systems.
