Working Principles of M39003/01-3091/TR

M39003/01-3091/TR capacitors are anodic tantalums, meaning that the plates of the capacitor are formed from an anodic layer of Ta2O5 coated onto a tantalum metal lug. The dielectric layer is formed when a voltage is applied to the plates, allowing current flow in one direction and blocking it in the other. This behavior is called rectification, and it is what makes tantalum capacitors suitable for use in pulsed-current applications.

The other important factor in tantalum capacitors is the self-healing characteristic. When a defect forms in the dielectric layer, current flow generates heat, which reduces the size of the defect and effectively restores the capacitor to its original working condition.

Conclusion

M39003/01-3091/TR is a tantalum capacitor with a wide range of applications. Its features include voltage rating of up to 50V, ESR ratings from 0.2 ohm to 3.0 ohms, temperature range from -55°C to +125°C, and insulation resistance of >5000 MΩ. It is suitable for filtering, bypassing, and energy storage. Moreover, its rectification and self-healing characteristics make it particularly suitable for pulsed-current and energy storage applications.
