Decrease of C in CPTCs is greater than in MnO2 capacitors. Soldering increases ESR in most types of capacitors, but the level of variations is lot-related. Soldering results in drying off capacitors by 50 to 93%. To be presented by A. Teverovsky at the NEPP Electronics Technology Workshop (ETW), Greenbelt, MD, June 15-18, 2020 8.

Tantalum capacitors are innately polarized capacitors with positive and negative lead and are appropriate with DC supplies. The polarity and markings on the capacitors make it easy to identify the anode and cathode. Two bands and a positive sign helps in identifying the value of capacitance and maximum working voltage.

· Tantalum capacitors are typically polarized. This means that they can only be connected to a DC energy supply observing the correct terminal polarity. Ceramic capacitors, on the other hand, are non-polarized and can be safely connected to an AC source. By not being polarized, ceramic capacitors have a better frequency response.
