The ±20 % tolerance is typical for tantalum capacitors and is acceptable for most decoupling and filtering roles where the exact capacitance is not critical. ## 500 mOhm ESR and the thermal budget The 500 mOhm ESR sets the self-heating floor under ripple current. For a 68 µF cap on a 12 V rail switching at 500 kHz, the ripple current is typically a few hundred mA — the I²R loss stays under 50 mW, well within the part's thermal budget. If your application pushes ripple above 1 A RMS, the ESR will dominate the temperature rise, and you may need a lower-ESR polymer or ceramic alternative. ## Molded case, size code C — footprint and layout The molded case in size code C (2312 / 6032 Metric) measures 6.00 mm x 3.20 mm with a seated height of 2.80 mm max. No via-in-pad or thermal-pad considerations — just a standard two-pad land pattern.","metaTitle":"TAJC686M020RNJ KYOCERA AVX 68 µF Molded Tantalum Capacitor","metaDescription":"TAJC686M020RNJ from KYOCERA AVX: 68 µF, 20 V, ±20% tolerance, 500 mOhm ESR, -55°C to 125°C.
