The TAJA155K035A is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 1.5 µF at 35 V with ±10% tolerance. In a 1206 (3216 Metric) package, it fits standard reflow assembly. The 7.5 Ohm ESR is moderate for this capacitance — it means the cap can handle a few hundred mA of ripple current before self-heating becomes a concern.
It is at home in an engine-bay ECU on a summer grade, in outdoor telecom gear that freezes overnight, or in downhole instrumentation where ambient hits 125°C. The molded case and surface-mount package keep it robust against vibration.
Active production — order without the scramble
This is a standard production part you can quote against a BOM line without worrying about forced redesign.
