The SM3521-101M(f) Power Inductors are a small-sized, RoHS-compliant surface-mount device manufactured by Zhenhua Fu. They have a rated inductance of 100uH ±20%, with a maximum current rating of 100mA. The physical dimensions are 3.5mm (L) x 3mm (W) x 2.1mm (H). These components are ideal for use in power conversion applications, in particular switched-mode power supplies (SMPS), power supplies, and AC-/DC-DC converters. They feature a low DC resistance, high self-resonant frequency, and low magnetizing current, allowing for high efficiency and reliable operation.
