Tantalum Surface Mount Overview


KEMET’s family of solid tantalum chip capacitors is designed and manufactured with the demanding requirements of surface mount technology in mind. These devices extend the advantages of solid tantalum technology to today’s surface mount circuit applications. Complementing multilayer ceramic chip convenience with capacitance ratings through 1500 μF, tantalum chip capacitors permit circuit designers to take full advantage of the benefits of surface mount technology.

Solid tantalum capacitors are usually applied in circuits where the AC component is smaller than the DC component. Typical uses of the tantalum surface mount capacitor include: blocking, by-passing, decoupling, and filtering. Because tantalum capacitors can experience scintillation or self-healing, which means their circuit impedance should not exceed 100KΩ. Exceeding 100KΩ will circumvent the scintillation and degrade leakage.

These components are RoHS compliant.
