Rated 15 µF with a 10 V DC voltage rating, this part provides bulk capacitance for 3.3 V and 5 V supply rails with a 50 % voltage derating margin — a standard practice for tantalum capacitors to avoid surge failures. The ±20 % tolerance is typical for tantalum electrolytics; the actual capacitance at the operating voltage will be near the nominal value because tantalum does not exhibit the DC-bias derating seen in Class 2 ceramics. ## 2 Ohm ESR and 1206 footprint The 2 Ohm ESR sets the self-heating limit under AC ripple. At 125 °C and full rated voltage, the ripple current should be kept below ~200 mA RMS to stay within the allowable temperature rise — check the TAJ series ripple-current derating curve in the datasheet. Housed in a 1206 (3216 Metric) molded case measuring 3.20 mm x 1.60 mm with a seated height of 1.20 mm (0.047\"), this part fits standard 1206 PCB pads. The low profile suits dense assemblies where clearance above the board is tight.","metaTitle":"TAJS156M010RNJ KYOCERA AVX TAJ Series 15 µF 10 V Molded","metaDescription":"Active-production TAJS156M010RNJ: 15 µF, 10 V, ±20%, 1206 case, 2 Ohm ESR, -55 to +125 °C.

However, ceramics exhibit DC-bias capacitance loss (typically 30-50 % at 5 V), so you may need a higher nominal capacitance to match the effective capacitance. Tantalum also has a different ESR profile, which affects ripple current handling and transient response.
