PM1210-121J-RC is a 120 µH chip inductor from the Bourns PM1210 Series, engineered for high-frequency RF and mobile communication circuits. The inductor features a ferrite core with enamelled copper wire and epoxy resin enclosure, delivering a minimum quality factor (Q) of 20 at 0.796 MHz test frequency and a self-resonant frequency (SRF) of 10 MHz maximum. With a DC resistance (DCR) of 11 O maximum and rated DC current (IDC) of 70 mA, this component exhibits excellent resistance to heat, humidity, mechanical shock, and pressure, making it suitable for automatic surface mounting. The ±5% inductance tolerance and operating temperature range of -40°C to +125°C ensure reliable performance in mobile phones, cellular devices, and other compact RF applications.
