0.68 µF at 50 V — decoupling and filtering fit
The TAJA684M050RNJ: 0.68 µF capacitance with a 50 V rating gives a 1.5× derating margin on a 33 V rail — typical for 24 V industrial supplies. The ±20% tolerance is standard for tantalum electrolytics; the actual capacitance at 50 V bias will sit near the low end of the band due to DC voltage derating. 7.9 Ohm ESR at 100 kHz limits the ripple current to roughly 80 mA RMS at 85°C ambient before self-heating becomes a concern. For low-frequency ripple (50/60 Hz), the ESR is higher — budget accordingly in bulk storage applications.
1206 case — board layout and storage
The 1206 (3216 Metric) case, 3.20 mm × 1.60 mm footprint, sits on a standard pad layout with 0.50 mm minimum pad-to-pad spacing.
