The FNR5040S3R6MT is a power inductor that is manufactured by Changjiang Microelectronics. This component is a 3.6uH ±20% 3.3A SMD power inductor with a 5x5x4mm case size that meets RoHS specifications. The inductance stability of the inductor is sufficiently high, enabling it to withstand high current levels in a variety of applications, such as DC-DC converters, buck and boost converters, motor control circuits, and power supplies. The inductor also has a ferrite core that aids in suppressing harmonic interference in the circuit, helping to ensure smooth operation and reduce EMI. Its small size, low DC resistance, and high inductance make it an ideal choice for space-constrained designs.
