The KEMET T491B156M016AT4053 is an industrial-grade MnO₂ solid tantalum surface-mount capacitor from the T491 Series. It provides 15µF capacitance, a 16V DC rating, and ±20% capacitance tolerance. The T491 family is designed for automated surface-mount assembly and meets or exceeds EIA Standard 535BAAC.
The device uses a B Case / EIA 3528-21 (1411) package measuring approximately 3.5 × 2.8 × 1.9mm, with a maximum seated height of approximately 2.1mm. Maximum ESR is 2Ω at 100kHz and 25°C, maximum DC leakage current is 2.4µA, and maximum dissipation factor is 6% at 120Hz and 25°C.
Maximum allowable ripple current at 100kHz is 206mA at 25°C, 185mA at 85°C, and 82mA at 125°C. The capacitor operates from -55°C to +125°C, is rated MSL Level 1, and supports reflow temperatures up to 260°C.
The T491 Series features molded construction, laser marking, and standard 100% matte-tin terminations. It is RoHS compliant and lead-free. Typical applications include decoupling and filtering in DC-DC converters, portable electronics, telecommunications equipment, and control units. The T491B156M016AT4053 is supplied on tape and reel with a standard factory quantity of 2,000 pieces.
