The B82730U3451A020 is a current-compensated U-core double choke designed for power line common-mode interference suppression. It features a rated inductance of 10 mH per winding at 10 kHz, with an inductance tolerance of -30/+50%. The component is rated for a maximum current of 450 mA at 50 Hz and +40 °C, and a voltage rating of 300 V AC at 50/60 Hz. The DC resistance is typically 1.75 Ohm per winding. The stray inductance is approximately 1.3% of rated inductance, providing symmetrical interference suppression. The choke is housed in a vertical, through-hole package with 4 PC pins and lead spacing of 7 x 8 mm. It operates over a temperature range of -40 °C to +125 °C. The terminals are made of CP wire, hot-dipped. The component is suitable for wave soldering and is RoHS-compatible. It is designed for applications such as compact switch-mode power supplies, electronic ballasts, and white goods.
