RB8522-16-3M0

Overview

The RB8522-16-3M0 is a two-wire vertical mount common mode choke from the Schaffner RB series. It features an inductance of 3 mH with a tolerance of -30% to +50%. The component supports a maximum DC current of 16 A and has a typical DC resistance of 8.4 mΩ. It operates within a temperature range of -40°C to +125°C and withstands up to 1000 V AC/DC. The self-resonant frequency is 400 Hz, with a lead pitch of 5.08 mm.

Feature Summary

• Provides effective common mode noise suppression for two-wire circuits
• Designed for high current handling capabilities up to 16 A
• Vertical through-hole mounting style for PCB integration

Applications

• Electromagnetic interference filtering in power supplies
• Noise reduction in industrial control systems
