Do conductive polymer capacitors absorb moisture?

However, conductive polymer capacitors are rated to Moisture Sensitivity Level 3 [MSL 3] and they will slowly absorb moisture once unsealed and exposed to the environment. Out-gassing may occur during reflow mounting if the parts are handled in violation of MSL 3 required practices. Q: Are conductive polymer capacitors susceptible to vibration?

What is the difference between conductive polymer capacitors and tantalum capacitors?

A: The construction of conductive polymer capacitors is basically the same as of tantalum capacitors with MnO2 solid electrolyte. The major difference is in the material used to create the solid electrolyte.

Are conductive polymer capacitors process sensitive?

A: Yes, conductive polymer capacitors are process sensitive. PSL classification to JEDEC J-STD-075 for product series T50, T51, T52, T55, T56 and T58: R4G; for product series T54 and T59: R6G. Q: How does the capacitance of conductive polymer capacitors change with voltage and temperature?

Why do conductive polymer capacitors have a lower ESR than MnO2?

Electrical conductivity of ICP is several orders of magnitude higher than that of MnO2. As a result, conductive polymer capacitors have a much lower ESR. Conductive polymer capacitors require essentially lower level of DC voltage derating comparing to MnO2.

Are conductive polymer capacitors better than MnO2?

As a result, conductive polymer capacitors have a much lower ESR. Conductive polymer capacitors require essentially lower level of DC voltage derating comparing to MnO2. Another feature of conductive polymer capacitors is the absence of an ignition failure mode due to less oxygen content.

How reliable is a conductive polymer capacitor?

For reliable capacitor performance, it is recommended that the DC voltage applied to the capacitor not to exceed the recommended derated value, see chart below. As an example, if a conductive polymer capacitor is used without any derating, failure rates of 0.1 % to 1 % will occur.
