er Science and TechnologyThe SMRH74-221M(f) Power Inductor is a 220uH ±20% 360mA SMD inductor, with a maximum size of 7.3 x 7.3 x 4.5 mm, manufactured by Zhenhua Fuer Science and Technology, and which conforms to the RoHS standards. It is a surface mount device designed for use in high-current, high-frequency power conversion circuits such as DC-DC, switch mode power supplies, and telecom transmitter circuits. It has a low profile, allowing it to be used in products with restricted space, and is rated for an operating temperature of -25°C to +125°C. It also features high inductance, low DC resistance, and high permeability for higher current rating.
