Gowanda’s CF4H1812-221G is a high-performance ferrite surface mount chip inductor designed for demanding electronic applications. Weighing just 0.12 grams, this compact component measures 4.8 × 2.7 × 2.9 mm and belongs to the CF4H1812 series. It features a surface mount technology (SMT) mounting type and offers an inductance of 2.2 µH with a minimum Q factor of 50. The inductor is tested at a frequency of 7.9 MHz, with a DC resistance of 0.48 Ω and a self-resonant frequency of 170 MHz. It supports a current rating of 0.83 A DC and maintains a tolerance of ±2%. The termination type is RoHS compliant with a copper finish, and the core is made of ferrite. Although it is not shielded, it operates efficiently within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, it is also fungal inert, making it suitable for a variety of high-reliability applications.
