Wirewound ceramic chip inductor provides 20 nH nominal inductance in a 0402 (1005 metric) surface-mount body. The 0402CS series uses a ceramic core and is characterized for RF applications with typical Q values of 52 at 900 MHz and 53 at 1.7 GHz for the 20 nH value. The device has a 3.00 GHz minimum self-resonant frequency, 0.25 ohm maximum DC resistance, and 420 mA reference Irms for a 15°C rise. Operation is specified from -40°C to +125°C ambient with a +140°C maximum part temperature.
