Mn-Zn Ferrite SQ1414 Type Cores for Transformers

Advantages:

1. Low High-Power Loss: SQ Manganese-Zinc Power Cores exhibit low power loss under high-frequency and high flux density operating conditions. This characteristic makes them excel in high-frequency applications, contributing to overall energy efficiency improvement.

2. High Saturation Flux Density: These cores have a high saturation flux density, allowing them to withstand significant flux changes without distortion. This is particularly important for applications like switch mode power transformers that involve substantial magnetic energy conversion.

3. Stable Temperature Characteristics: SQ Manganese-Zinc Power Cores maintain stable performance over a wide temperature range, making them suitable for electronic devices in various environmental conditions.

4. High Curie Temperature: The Curie temperature is a critical parameter for magnetic materials. SQ Manganese-Zinc Power Cores feature a high Curie temperature, ensuring they retain good magnetic properties even at elevated temperatures.

5. High Resistivity: Compared to metallic magnetic materials, SQ Manganese-Zinc Power Cores have a significantly higher resistivity. This helps suppress eddy currents within the circuit, reduce high-frequency noise, and expand the usable frequency range of the core.

6. Good Chemical Stability: Manufactured using ceramic processes, SQ Manganese-Zinc Power Cores are chemically stable and rust-resistant, enhancing their durability and reliability.

Application Fields:

1. Switch Mode Power Transformers: Due to their low loss, high saturation flux density, and stable temperature characteristics, SQ Manganese-Zinc Power Cores are widely used in switch mode power transformers. These transformers convert grid voltage to DC voltage suitable for electronic devices.

2. Choke Coils: Choke coils are components in electronic devices that block the passage of high-frequency AC current. SQ Manganese-Zinc Power Cores, with their high inductance and low loss properties, are ideal for manufacturing choke coils.

3. EMI/RFI Filters: In electronic devices, electromagnetic interference (EMI) and radio-frequency interference (RFI) are common issues. SQ Manganese-Zinc Power Cores can be used to create EMI/RFI filters, reducing the impact of these interferences on device performance.

4. Audio Transformers: Audio transformers are used for transmitting and processing audio signals. SQ Manganese-Zinc Power Cores, with their high fidelity and low loss properties, are well-suited for audio transformer manufacturing.

5. Energy-Saving Lamps and Electronic Ballasts: SQ Manganese-Zinc Power Cores play an important role in lighting equipment such as energy-saving lamps and electronic ballasts. They help improve the energy efficiency and performance of these devices.
