99.6% Alumina Ceramic Substrate For Making Chip Resistors

99.6% Alumina Ceramic Substrate For Making Chip Resistors Great Electrical Insulation: The 99.6% alumina ceramic substrate is really good at insulating electricity. Its volume resistivity is super high, usually more than 10¹⁴ Ω·cm. This high insulation feature makes sure that there won't be any current leakage between different parts of the chip resistor and the components around it. It gives the resistor a stable electrical environment so that it can work precisely as a part for controlling the flow of electric current.  Dielectric Constant: The dielectric constant of the substrate is about 9 - 10. This number has an impact on the capacitance between different parts of the resistor and the substrate. A stable and proper dielectric constant is needed for the chip resistor to work accurately in high-frequency situations. It also affects the impedance and how signals are transmitted in the resistor-substrate system.       99.6% Alumina Cera…
