What is a tantalum capacitor?

A capacitor is a component that temporarily stores electricity. It is important how much electricity can be stored in the capacitor. Therefore, capacitors that use tantalum, which has very good characteristics in terms of storing electricity, are used.

[Applications]

PC, mobile phone
Video games,
Digital camera, car navigation system
Digital video, DVD, etc.

Examples of using tantalum capacitors

Tantalum capacitor anode element (pellet)

The tantalum capacitor anode element is the "element" that becomes the electrode in the tantalum capacitor, and is the most important part. PML produces tantalum capacitor anode elements.

tantalum

[Origin and history]

Tantalum is a substance extracted from ore. This ore also contains a substance called niobium. Founded in 1743 and nearly 70 years later, a Swedish scholar named it "tantalum". The scholar named him "tantalum" because he was frustrated to separate the elements of tantalum. ("I'm frustrated" is called "tantalum" in Greek.)

[Feature]

It is a metal with excellent chemical resistance and heat resistance, and has good chemical stability and corrosion resistance. It produces the most stable anodic oxide film among all metals. It is high and resistant to chemicals, so it is used not only for capacitors but also for medical products (such as bone grafting materials).
