ESR and circuit impact
The TAJT684K020RNJ: With a 15 Ohm ESR, this part is best applied in low-frequency decoupling or DC-blocking roles where ripple current is modest; the ESR limits the capacitor's ability to absorb high-frequency AC without self-heating.
Housed in a molded 1411 (3528 Metric) case, the 3.50 mm x 2.80 mm footprint and 1.20 mm seated height keep it compact for dense surface-mount assemblies.
