Panasonic polymer capacitors (Hybrid / OS-CON / POSCAP / SP-Cap) have excellent temperature characteristics.
Hybrid: stable ESR value over temperature, even within low temperature range!
OS-CON: stable ESR and capacitance value over temperature v.s. other types.
POSCAP: stable ESR and capacitance value over temperature v.s. ceramic capacitors.
Polymer Caps: stable capacitance value over temperature v.s. MLCC.
