Product Description Excellent Electrical Insulation Alumina Ceramic Substrate Al2O3 Aluminum Oxide PlateProduct FeaturesAlumina ceramics boast exceptional insulation properties, making them one of the top insulating materials. Their characteristics include:1. Extremely high volume resistivity and dielectric strength, effectively isolating high voltages.2. Low and stable dielectric constant and dielectric loss, making them particularly suitable for high-frequency and high-speed circuits.3. Its most prominent advantage is its ability to both insulate and conduct heat, a property unmatched by most organic insulating materials. This solves the heat dissipation challenges faced by high-power electronic devices.4. Its stable performance is minimally affected by factors such as temperature, humidity, and aging, resulting in extremely high reliability.Product SpecificationsWe can make various specifications.
