What Is a Ceramic Fiber Board?

A ceramic fiber board is an insulating material made from ceramic fibers as a substrate.

It provides insulation due to its low thermal conductivity and porous structure. Ceramic fibers have low thermal conductivity, making it difficult for heat to transfer, thus providing excellent insulation. Additionally, the porous structure contains numerous air pockets, which hinder heat convection.

In the construction industry, it is used as insulation for walls and roofs, while in industrial settings, it serves as insulation for high-temperature furnace walls and ceilings. In pottery, it acts as insulation for kilns, and in the automotive industry, it is utilized as insulation for exhaust pipes and engine surroundings. Ceramic fiber boards are composed of ceramic fibers and binders. The ceramic fibers are extremely fine, fibrous materials, while the binders are adhesives that solidify these fibers.

What Is an Inductor Choke?

An inductor choke is a passive component used to achieve stable current supply in power lines and suppress high-frequency noise.

Generally constructed with coil-shaped conductors and a magnetic core, it impedes high-frequency currents and allows low-frequency currents to pass through, based on a property called inductance. Inductor chokes operate based on the properties of inductance and the magnetic core. The current flowing through the coil generates a magnetic field, which attempts to sustain the current. Additionally, the magnetic core concentrates the magnetic field, effectively suppressing high-frequency noise.

Inductor chokes find applications in various fields such as power circuits, electronic devices, communication equipment, and medical devices. Its main components include the coil and the magnetic core. The coil serves as the conductor for current flow, while the magnetic core is used to concentrate the magnetic field.

What Is a Switch Chip?

A switch chip is a semiconductor chip responsible for switching functions within an electronic circuit.

Unlike traditional mechanical switches, it offers small size and high-speed operation, making it widely used in various electronic devices.
