Notes


1. The heat sink is optional and P/N: 7G-0020C-F.

The LWB60 Series standard module meets EMI class A or class B with external components.

3. An external filter capacitor is required if the module is to meet EN61000-4-4, EN61000-4-5

The LWB60 recommended an aluminum electrolytic capacitor (Nippon cheni-con KY series, 220μF/100V) and a TVS (SMDJ120A, 120V, 3000 Watt peak pulse power) to connect in parallel.
