What Are The Advantages Of CT81 High-Voltage Ceramic Capacitors?

As a type II ceramic dielectric capacitor specifically designed for high-voltage scenarios, the WEET WCA CT81 high-voltage ceramic capacitor has the following advantages:

  1. Excellent High-Voltage Withstand Capacity.

    Its rated operating voltage generally ranges from 1kV to 6kV (WEET also offers models with voltages of 10kV, 15kV, and 25kV)

  2. Compact Size.

    Most of them are in a disk shape with a compact pin layout, which saves PCB board layout space.

  3. Stable Structure.

    The electrodes of CT81 capacitors adopt the "silver infiltration firing" process, and most of their exteriors are protected by an insulating coating.

  4. Good High-Frequency Characteristics.

Summary: 

The essence of the advantages of CT81 high-voltage Disc Ceramic capacitors pulse-proof lies in that they are "tailor-made for high-voltage and medium-to-high-frequency scenarios".

Note: 

Its shortcomings are weak temperature stability and it is not suitable for use in pulse circuits.

What Is The Price Of CT81 Ceramic Capacitors?

The price of CT81 High Voltage Radial Leaded Disc Ceramic Capacitor is affected by a variety of factors:

1. International trade policies and tariffs.

2. Specification parameters:

  • Capacitance: The larger the capacitance, the more complex the production process, and the higher the price.

  • Rated voltage: The higher the rated voltage, the higher-quality materials and more complex manufacturing processes are required, and the price will increase accordingly.

  • Precision: CT81 Disc Ceramic capacitors pulse-proof with higher precision grades require more complex manufacturing processes, so their prices are naturally higher.

3. Raw material prices: The main raw materials of CT81 High Voltage Radial Ceramic Capacitors 10KV-15KV are barium titanate and rare earth materials, which directly affect the cost of CT81 ceramic capacitors. 

CT81 DC Ceramic Disc Capacitor (CG-CT81-472M) is cross-compatible with KEMET CGP Series, TDK CK45, Vishay HAZ, HAE, HAX 1 kVDC, HBZ, HBE, etc.

What Is The Cost Of MER CL21 Film Capacitor?

The WEET CL21 MER Metallized Polyester Film Capacitor is one of the common models in the MER series, and its cost is affected by multiple factors such as raw materials, production processes, and performance parameters. 

1. Core Raw Material Costs (Accounting for the Highest Proportion, Directly Determining the Basic Cost)

  • Metallized polyester film.

  • Lead materials.

  • Packaging materials. 

2. Compliance and Certification Costs (High-Standard Certifications Increase Costs)

  • For consumer products: They only need to comply with China's GB standards and the EU's CE standards, resulting in relatively low certification costs.

  • For automotive electronics: Compliance with AEC-Q200 certification is required, which involves high costs.
