CM322522-180KL is a chip inductor from the CM322522 series featuring an inductance of 18 µH with ±10% tolerance. The device exhibits a minimum quality factor (Q) of 30 at a test frequency of 2.52 MHz, with a self-resonant frequency (SRF) of 20 MHz minimum and a maximum DC resistance (DCR) of 3.3 O. It supports a rated DC current (IDC) of 120 mA at 20°C, with inductance dropping 10% at rated current. The inductor is constructed with a ferrite core, enamelled copper wire, and epoxy resin enclosure with tin-plated terminals, offering high resistance to heat, humidity, mechanical shock, and pressure. Its compact dimensions (2.90 × 3.20 × 2.20 mm) and accurate tolerances make it ideal for automatic surface mounting in mobile phones, cellular devices, and other compact RF/IF applications.
