EPCOS / TDK B82791H2 Power Line Chokes

EPCOS / TDK B82791H2 Power Line Chokes offer a 250VAC rated voltage, 1.5A to 4A current range, and a maximum nominal inductance of 100µH. B82791H2 chokes have a compact design, making them suitable for post-design EMC tuning on finished PCBs. These chokes feature a high resonance frequency and high saturation capability due to special core material and omission of potting. EPCOS / TDK B82791H2 Power Line Chokes are ideal for LED driver circuits, suppression of common-mode interferences at high frequencies, and switch-mode power applications.
