TFP410: TFP410 Tantalum Capacitors Replace Ceramic Capacitors

Alon Chen

Part Number: TFP410

Dears，

1. May I ask, can these tantalum capacitors of TFP410 be replaced with ceramic capacitors of the same capacitance?

2.Tantalum capacitors are recommended in the manual, why are tantalum capacitors recommended? Tantalum capacitors are difficult to buy, what other types of capacitors can I replace?

Hi,

When looking at capacitance changes with applied voltage, tantalum capacitors show consistent stability whereas ceramic capacitors do not. In response to higher applied voltages, the permittivity of the dielectric shrinks within the ceramic capacitor and causes changes in capacitance.

Please refer to this app note when trying to replace the tantalum capacitor with ceramic capacitor, https://www.ti.com/lit/an/slva214a/slva214a.pdf.

Thanks

David
