Part identity and key ratings
Taiyo Yuden EMK063AC6104KP-F is a 0.1 µF surface-mount MLCC in the 0201 (0603 metric) package, rated 16 V with an X6S temperature coefficient. X6S captures capacitance drift from -55°C to 105°C — a wider swing than X5R but still Class II, meaning it is not a precision capacitor; the ±10% tolerance covers the base value at 25 °C reference. The body sits at 0.35 mm thick in a 0.60 mm × 0.30 mm footprint — standard 0201 geometry that fits under ball-grid passives on dense SMPS layouts. Rated for -55°C to 105°C operation, which covers most industrial and consumer power-supply ambient ranges without derating the dielectric.
SMPS filtering fit and sourcing posture
Listed for SMPS filtering — the X6S dielectric provides decent voltage linearity at the rail bypass positions where 16 V is well below the rated ceiling, leaving margin against transients on a 12 V bus. The 0.1 µF value is a standard decoupling/bulk-capacitor density for low-current rails; verify the ripple current rating against the switching node if this is a primary filter element. Production status is Active.
