The Bourns DR221 series of surface mount data line chokes are designed to suppress EMI in data and signal lines, making them ideal for sector windings and a wide range of applications. These chokes feature a high-quality toroidal core, RoHS compliance, and are rated for operation from -40°C to +125°C. They offer a balance of performance and size, making them suitable for space-constrained designs. The DR221-333AE specifically provides an impedance of 33.0 µH with a tolerance of +50%/-30%, and is designed for efficient signal management in modern electronic systems.
