The Bourns DR221-513AE is a surface mount data line choke engineered for effective electromagnetic interference (EMI) suppression in various data and signal line applications. Its toroidal core construction ensures high performance across a broad frequency spectrum, making it ideal for sector windings and other critical circuit designs. The choke is rated for voltages up to 50 Vdc/100 Vac and handles currents from 0.1 to 0.25A. Constructed with enameled copper wire, an LCP base, and Cu/Ni/Sn terminals, the DR221-513AE is designed for reliable operation within a temperature range of -40°C to +125°C. Its compact size and surface mount design simplify integration into modern electronic assemblies.
