Capacitance and voltage for rail decoupling
This TAJB156M006RNJ is a 15 µF tantalum capacitor rated at 6.3 V, ±20% tolerance — a common value for bulk decoupling on low-voltage supply rails where the derating rule keeps the applied voltage within safe limits. The molded case and surface-mount package (1411 / 3528 Metric) suit automated pick-and-place assembly; the B-size case code matches a standard footprint for reflow soldering.
Temperature grade and deployment fit
The TAJ series is a general-purpose line (Features: General Purpose), so it is not AEC-Q200 qualified; for automotive-grade requirements, look to the AVX F95 or TPS series.
