AC Safety Capacitors
X/Y Capacitors: Some safety capacitors come with a combination designation, for example, X1/Y2. This simply means that the capacitor can be used as an X1 capacitor in an across-the-line application or as a Y2 capacitor in the line-to-ground portion of the circuit. Tecate offers both X1/Y2 and X2/Y3 multilayer ceramic safety capacitors.

Types of Insulation Materials for Wire and Cable
Semi-Rigid PVC (SR-PVC) is mainly used as primary insulation and is very abrasion-resistant. SR-PVC insulation also has heat, water, acid, and alkali resistance, along with being flame-retardant. For 30-16 gauge wire, a 10-mil. wall meets the UL-style UL 1061 (80 degrees Celsius, 300 volts). Plenum Polyvinyl Chloride (Plenum PVC)
Ceramic Capacitor FAQ and Application Guide
Insulation resistance measurements shall be made between the capacitor terminals on a megohm-meter or an insulation resistance test set. Measurements need to be made immediately after a 2-minute period of uninterrupted test voltage application and a charging current limited to 50 mA using the following measurement conditions:
