1 µF, 25 V, AEC-Q200 — automotive-grade tantalum for harsh environments
Its AEC-Q200 qualification makes it suitable for automotive electronics where reliability under temperature and vibration is mandatory — think engine control units, transmission sensors, or infotainment power rails.
With an ESR of 8 Ohm at 100 kHz, this capacitor is best suited for low-frequency decoupling or bulk storage rather than high-ripple switching supplies — the ESR limits the ripple current handling and contributes to self-heating. For a 1 µF part in a typical automotive filter, the 8 Ohm ESR is acceptable for signal conditioning or as a local bypass for an IC's power pin.
