Small Ceramic Insulation

Q: Why does my electronic device always malfunction in high temperature, high pressure, or high frequency environments? Is there a material that can withstand high temperatures and maintain stable insulation?
A: Small ceramic insulators are designed to solve such problems. It can provide excellent electrical insulation and structural support in extreme temperatures (-200 ℃~1600 ℃), strong electric fields, high-frequency signals, and corrosive environments, effectively preventing short circuits, breakdowns, thermal failures, and ensuring long-term stable operation of equipment.

What is a small ceramic insulator?
Small ceramic insulators are miniature insulation components made from advanced ceramic materials such as high-purity aluminum oxide (Al ₂ O3), aluminum nitride (AlN), or zirconium oxide (ZrO ₂) through precision molding and high-temperature sintering processes. Its typical dimensions range from a few millimeters to tens of millimeters, and it is widely used in fields such as power electronics, aerospace, new energy, medical equipment, and semiconductor manufacturing.

Core application scenarios
-New energy vehicles: used for high-voltage isolation in battery management systems (BMS), DC-DC converters, and motor controllers.
-Industrial power module: Provides dual functions of heat dissipation and insulation in power devices such as IGBT and MOSFET.
-RF and microwave communication: as a low dielectric loss support component for high-frequency connectors and antenna feeding systems.
-Medical imaging equipment: Ensure signal purity and patient safety in high-precision instruments such as CT and MRI.
-Aerospace and Military Industry: Enduring electrical stress in extreme environments in satellite power and radar systems.
