Product details

The molded epoxy case provides consistent dimensional control and good moisture resistance compared to conformally-coated chips — relevant if the board sees conformal coating or operates in humid environments.

1.5 µF at 20 V — where the margin lives

Rated 20 V with 1.5 µF capacitance at ±10% tolerance. For a 12 V rail, this gives 8 V of headroom — enough to absorb typical transients without derating the voltage below the recommended 50 % margin for tantalum capacitors. The 6.5 Ohm ESR at 100 kHz sets the ripple current ceiling: at 100 kHz, the self-heating from ripple current is I² × ESR; keep the RMS ripple below ~150 mA to stay within the 2000-hour lifetime at 125°C.

For outdoor telecom or downhole tools that cycle between -40°C and 85°C, this part has margin on both ends.

Frequently asked questions

What is the footprint and case code for TAJA155K020HNJ?

The capacitor uses the 1206 (3216 Metric) case with manufacturer size code A. Dimensions are 3.20 mm x 1.60 mm with a seated height of 1.80 mm max. The footprint matches standard 1206 solder pads — no special layout required.

Is TAJA155K020HNJ RoHS compliant?

The part carries General Purpose features and is supplied on Tape & Reel. RoHS compliance is standard for the TAJ series, but the specific RoHS status should be confirmed at quote time against the date code lot.
