Tantalum Capacitors vs Ceramic: ... For voltage connected tantalum capacitor has consistent stable voltage while ceramic does not. As a result high voltage permittivity of dielectric shrinks in ceramic capacitors and causes variation in capacitance. The variation in capacitance of ceramic capacitors is linear and easily accounted for.
X7R vs. X5R Capacitor: What''s the Difference?
X7R ceramic capacitors are known for exhibiting a high degree of capacitance change with applied voltage, ranging from -15% to +30%. On the other hand, X5R ceramic capacitors have much better temperature and voltage stability, with a tolerance range of -22% to +80%.
