TDK-Lambda RTHB-5150 Power Line Filter

TDK-Lambda RTHB-5150 is a 3-phase power-line EMI filter rated for 150 A and 500 V AC, designed to suppress conducted noise on three-line power feeds used by industrial drives and power electronics. This book-style module accepts 500 V AC input and 500 V DC on its lines, with a line-to-earth withstand voltage of 2,500 V for 60 seconds and a minimum insulation resistance of 100 MΩ at 500 V DC for 1 minute. It delivers robust attenuation with at least 25 dB of common-mode suppression from 0.1 MHz to 10 MHz and at least 25 dB of differential-mode attenuation from 0.2 MHz to 30 MHz. The unit carries an SCCR of 10 kA and exhibits a maximum DC resistance of 6 mΩ. Its dimensions are 100 mm (L) × 534 mm (W) × 234 mm (H) in a book-style package suited to rack or enclosure mounting. Typical applications include motor drives, industrial inverters, CNC machines, and other 3-phase power electronics where reliable EMI suppression on the supply line is required.
