Note:

1. For Smart Home and Home Appliance applications two Y-capacitors are required in series (2.2 nF/250 Vac each) to meet 60335 household safety requirements.

2. Many safety standards require a bleeder resistor no greater than 3.8MΩ in parallel with the X-capacitor.

3. R1 must be a wire-wound resistor; do not use a chip or carbon film resistor.
