DR221-333AE is a surface mount data line choke from the Bourns DR221 Series, designed for the suppression of EMI in data and signal lines. It features a 33.0 µH inductance (measured at 10 kHz, 0.1 Vrms) with a tolerance of +50%/-30%, and operates over a frequency range of 30 to 250 MHz with a minimum impedance of 1000 O. The device has a maximum DC resistance of 0.27 O per winding and a rated current of 200 mA. Built with a high-quality toroidal ferrite core and sector windings, it offers reliable performance across an operating temperature range of -40 to +125 °C. This RoHS-compliant component is ideal for applications requiring effective noise filtering and signal integrity in data communication systems.
