SMRH125 Shielded SMD SMT PCB Power Inductor 10uH 470mH 4R7
Product performance:
The inductance value versus DC current over the relevant temperature range is a very important curve that must be obtained from the manufacturer. The rated saturation current (ISAT) can be found on this curve. ISAT is generally defined as the DC current when the inductance value is reduced by 30[[%]] of the rated value. Some inductor manufacturers do not specify ISAT. They probably only gave the DC current when the temperature was 40°C above ambient.
Feature:
1. Surface mount high power inductor.
2. It has the characteristics of miniaturization, high quality,
high energy storage and low resistance.
3. Mainly used in computer display boards, notebook computers,
pulse memory programming, and DC-DC converters.
4. Reel packaging is available for automatic surface mounting.
Application:
Products are widely used in digital products, PDAs, notebook computers, mobile phones, network communications, graphics cards, LCD backlights, power modules, automotive electronics, security products, office automation, home appliances, walkie-talkies, electronic toys, sports equipment and medical equipment, etc.
