Product Overview
The Y5P Series High Voltage Ceramic Capacitors are EIA Class II dielectric disc capacitors designed for demanding high-voltage applications requiring stable performance across a wide temperature range. Y5P is an industry-standard material widely used in general-purpose high-voltage applications, offering reliable performance from -25°C to +85°C with capacitance variation within ±10%.
These components feature a rugged ceramic disc construction with silver-plated electrodes and tinned copper-clad steel wire leads, encapsulated in a flame-retardant halogen-free epoxy resin coating.
Y5P dielectric capacitors are suitable for high-frequency applications up to 30KHz to 100KHz, making them ideal for a wide range of industrial and medical equipment.
Features
1. Compact size.
2. Excellent heat resistance, moisture resistance, and high dielectric strength.
3. Coated with halogen-free flame-retardant epoxy resin.
