The Bourns 79F221K-TR-RC is a conformal coated RF choke in the 79F series, offering 220 µH inductance with ±10% tolerance. It maintains a minimum quality factor of 40 at 790 kHz and a minimum self-resonant frequency of 5 MHz. The device is rated for a maximum DC resistance of 20 Ω and a maximum DC current of 35 mA, with a typical temperature rise of 35 °C at rated current.
The ferrite-core inductor is unshielded and uses enamelled copper wire with epoxy resin coating. It is designed for through-hole mounting in an axial package measuring 0.100" diameter by 0.160" length (2.54 mm x 4.06 mm). Terminal plating is Cu/Ni/Sn, and the component operates over -55 °C to 105 °C.
The 79F221K-TR-RC is supplied in ammo-pack packaging with 2,000 pieces per package. Its inductance is tested at 790 kHz, and the part is RoHS compliant per Directive 2011/65/EU.
