CW100505-39NJ is a surface-mount chip inductor designed for high-frequency RF and signal processing applications. It features an inductance value of 39 nH with ±5% tolerance, a minimum quality factor (Q) of 8 at 100 MHz test frequency, and a self-resonant frequency (SRF) minimum of 1800 MHz. The inductor exhibits a maximum DC resistance (RDC) of 1.7 ohm and supports a maximum DC current (IDC) of 150 mA. Constructed with a ferrite core and copper wire coil encased in epoxy resin with tin-plated terminals, this component demonstrates high resistance to heat, humidity, mechanical shock, and pressure. It is RoHS compliant and suitable for automatic surface mounting in compact 0402-size packages, making it ideal for mobile communications, wireless networks, and precision RF filtering circuits.
