We are also specializing in improving the things management and QC method in order that we could retain terrific edge inside the fiercely-competitive small business for 221 Inductor, Usb To Displayport Adapter, Step Up Transformer, As a leading manufacture and exporter, we appreciate a great status inside the international markets, especially in America and Europe, because of our top high-quality and sensible charges.

Wholesale Flat Inductor - High flux custom toroidal power inductor – Mingda Detail:

Although the toroidal coil inductance is an ideal shape in inductance, it is mainly used as a signal processing because of the high requirements. However, the small toroidal inductance is still very large. , Mainly used in high-frequency, high-sensitivity communication products.

The toroidal coil inductor is made of iron powder core as the material, mixed with resin, etc., so that the air gap is evenly distributed inside the iron powder core. The inductor has a certain degree of sensitivity. When we see the word Air gap, we know it is Used in power, therefore, the iron powder core toroidal coil inductor is the most commonly used type of power inductor, and the IDC can reach more than 20 amperes.

Capable of handling very high DC bias current with minimal inductance roll off.
Best suited for high Power, high AC & DC Bias at high Switching Frequency.

With current, inductance and working frequency, we could provide ideal products for you.

Main Advantages:

1. Excellent electromagnetic shielding due to toroidal design

2. Low cost designs with pre-tinned leads for PCB through hole mounting

3. Iron powder cores with low losses

4. Low magnetically leakage field

5. Operating temperature: –25 ºC to +125 ºC

6. Custom designs on request

7.Build to ROHS compliant and lead free
