1. How Do You Choose the Right Ceramic Terminal Block / Ceramic Connector ?
Ceramic terminal blocks are insulating components made mainly from steatite (C221 Steatite) and alumina (Alumina). They offer excellent high-temperature resistance, high dielectric strength, flame retardancy, and aging resistance.

Applications
Heating equipment: ovens, kilns, industrial furnaces, BBQ heating elements, heating rings, hot plates, stoves, toasters, coffee makers
Home appliances: microwave ovens, hair dryers, electric irons, water heaters, rice cookers, air fryers Sensors: thermocouples, platinum resistance temperature detectors (RTDs), resistance wire and heating wire connections
Lighting: halogen lamps, high-intensity discharge (HID) lamps, ballasts, high-temperature fixtures
Industry and power: heat treatment production lines, kilns, motor terminals, power distribution, high-temperature control panels

Ceramic vs. Plastic Terminal Blocks
Ceramic terminal blocks withstand high temperatures right next to the heating element — they do not melt or deform. Plastic terminal blocks cost less, but they are only suitable for low-temperature circuits.

How to Choose the Right Model
Ceramic material: steatite for standard conditions, 95% alumina for higher-temperature applications;Rated current and rated voltage;
Overall dimensions, mounting hole positions, and screw specifications;
Maximum operating temperature of your equipment;
Required compliance certifications (e.g., RoHS) .

2. How Do You Choose the Right Ceramic Material?
High-frequency / microwave insulation, operating temperature below 800°C → C221 high-frequency steatite.
General wear resistance, electronic insulation, standard applications, long-term service ≤ 1400°C → alumina.
Repeated thermal cycling, where thermal shock resistance matters most, long-term service ≤ 1200°C → cordierite.
Continuous high-temperature environments, high-temperature load-bearing refractory parts, long-term service ≤ 1500°C → mullite.
Applications requiring toughness, resistance to chipping, precision wear-resistant structural parts, operating temperature below 500°C → zirconia.
High temperature plus corrosion, where thermal conductivity and heavy wear resistance are needed, 1400°C class long-term service → silicon carbide.

3. Can You Customize Products?
Yes. We can produce samples from drawings, physical samples, or concepts, and then move on to mass production.

4. Do You Have Stock, and What Is the Lead Time?
Standard products such as ceramic terminal blocks and ceramic connector blocks are kept in stock — please contact your sales representative for current availability. In-stock items: 3 days. Production: 20–30 days. Custom products: 30–40 days, depending on complexity.

5. What Shipping Methods Do You Offer, and How Long Does Shipping Take?
Express delivery, sea freight, and air freight. Actual transit time depends on the shipping method and the destination.

6. How Do I Pay?
