First question: What is a power i© ∑nductor?

There are various opinions i ε¥♠n the industry about what a power>® inductor is. Although t£λ≤Ωhey are all correct, they are all on♥₹ e-sided. The editor bel♥<'☆ieves that the accura​★λ←te explanation is that ✔φ≥a power inductor ref≠≈↑ers to an inductor that must pa β‍±ss through a large current and withs≤​ βtand a high voltage at bo γ‍<th ends during operation.

The naming of power inductors i ±₹¶n the industry is mainly b<‍≥ased on their functions. Namα≤‌'es such as high current inductance ↑↑★and high-frequency inductance≤₽≠ are given in a similar ∏λδ≤way.

The second question: What is the funct₩÷φ∞ion of power inductance and what are thλ≥♦φe functions of power induδ∏ctance?

The power inductor has two functions, ₹&↕$serving as a choke (also known as a ♣↔'↔choke) or as a filter.

When the power inductor acts a★"λ↓s a choke, the self induced electromot♣π↔ive force generated by the inductor ☆₩varies inversely with the coil cu÷÷rrent, hindering the currenφφ§t change. According to the working f∞∏requency of the power inductor,✔★™¥ there are also high♠ -frequency power inducto↕∞rs (high-frequency choke) and low-frequβ¶ency power inductors (low-frequ₩ φency choke).

When used as a filter, the power&↔ inductor and capacitor can form an LC ∏©$ filtering circuit, w☆δhich uses LC resonance to filter o★ β✘ut signals of a specific α✔φfrequency. Similarly, based on the↕↓• operating frequency, t>↔here are differences betw€¥​•een high-frequency f&£≠ilters and low-frequency filters.

The third question: What±π≠  are the characteristics of po♠ ∞§wer inductance

According to definition,≥☆☆ power inductance has < ÷✔two characteristics:
1. Can pass through high curren≥✔→¥t;
2. The voltage at both ends≈×​φ of the inductor is high during oπ©γ>peration.

If manifested in appeara<φ÷nce, the wires used for power indu γctor coils are generally thicker (can≠∞£☆ pass through high curren"€✘ ts). If the coil wire is particulaγ✘‍©rly thin, the possibilit♠♠y of being a power inductor is∑ < basically ruled out.

Fourth question: What are the type☆ ©s of power inductors?

Divided by mounting ♥α÷method, it can be divided into chipφ<₩§ power inductors and ↑‌♠plug-in power inductors✔®π. In fact, when we look back at the ans"♦§wer to the question of what power ind​↔₽uctance is, we can see that powe'Ωr inductance is defined∏→×± by its working state®‍≠ε, without specifying which ε ‌form and structure it is. IΩ©®★n principle, as long as the condit✔€ions are met, any category such♦≈♣ as R-bar inductor, magneti®<→♦c ring inductor coil, and I-β>$εshaped inductor can be used as≈λ≈ power inductor,.

However, structurally ¶ speaking, traditional wound inducto&✔rs, I-shaped inductors, a®≤≥nd inductive coils are≤₹→≠ more suitable for making power in‌♠‌ductors. Color ring inπ§ductors and chip stacked₹≥'☆ inductors generally allow a small amπ¶ount of current to p&δass through, so they are rarely us∑ ≤ ed as power inductors.

Fifth question: What is the difference ✘‌δΩbetween power inductors and ordinary✔' inductors?

The difference between po↔€ ∑wer inductors and ordinary i ∑αnductors lies in their f±γΩunctionality. Power inductors rβ♠equire the ability to generate¶ ♣ sufficient self induced elec€'tromotive force for c♠'$λhoking or filtering. O₹↔rdinary inductors, o✘♥₽‍n the other hand, only need to geneΩ<rate a corresponding frequency signal.

Sixth question: Can powe§§r inductors and ordinarα÷£↕y inductors replace each o∞§ther?

In general, power inductors can rep‍↓lace ordinary inductors, but th ±β•e opposite is not possible.

Question 7: What is the differen☆  ₩ce between power inductanc✔↔e and shielding inductance?

The difference lies in the different c®×lassification standards. Power i♥↕nductors require high current anφγ≤d high voltage resistance in ter ±ms of functionality, whiπ±le shielding inductors indicate a shiel"♠≥ding structure. There i☆π≠s often an intersection b♥ etween two classificati§¶ ons, where an inductor is bot≥‌h a power inductor and a shielding ₩∞inductor.

Question 8: Which is thΩΩΩ£e best manufacturer of SMD power induct"≈'ors?

In the the Pearl River Delta φΩ∞γregion represented by DongguanΩ↔‍, Shenzhen, inductanc¥₩± e manufacturers account f™↑‌δor about 80% of the country. A profess₽§→ional inductance manufac≠↑'turer and supplier - Gain I‍↕± ndustry, has been supplyi©€≤←ng inductance to domestic high-tech≈♣ enterprises for many years, aλ∏♠nd has a complete quali&★ty management system and∏★ service standards. Prov ↑ide SMD power inductor manufacturers fo₹™γr direct sales, wholesale, and cust↑​omization.
