TDK B82725S2xA0 SurfIND High-Current Chokes

TDK B82725S2xA0 SurfIND SMD High-Current Chokes are current-compensated ring core double devices. These chokes can filter common-mode noise from a 24A to 36A current range at +70°C. Additional features include up to 1% stray inductance, 120μH to 820μH nominal inductance, and 0.78mΩ to 2.21mΩ resistance. The rated inductance drops by less than 10% at rated current with DC magnetic bias at 20°C. The SurfIND chokes are used to suppress common-mode interference, PCB assemblies for reflow-only soldering, and switch-mode power conversion. TDK B82725S2xA0 SurfIND SMD High-Current Chokes are ideal for applications with voltages up to 250VAC. The series complies with IEC/EN 60938-2 and features a compact footprint of 40mm x 38mm.
