The TPSR106K006A1500: This capacitance-voltage combination is a standard choice for bulk decoupling on 3.3 V and 1.8 V rails, providing enough charge storage to handle transient current demands from nearby ICs without excessive voltage droop.
ESR and temperature range — the real-world performance limits
With an ESR of 1.5 Ohm at 100 kHz, this capacitor's self-heating under ripple current is manageable for most decoupling and filtering applications — the ESR dominates the AC loss, so a 100 mA ripple current at 100 kHz dissipates about 15 mW internally. The ±10% tolerance is the standard grade for tantalum electrolytics; for a 10 µF part, the actual capacitance at room temperature falls between 9 µF and 11 µF, which is tight enough for most filter time constants and decoupling roles.
