That ESR number is the key design parameter for ripple current handling and self-heating.
Active production — no LTB scramble needed
Listed as Active. No last-time-buy window, no official successor — this part is in standard production and can be ordered for current and new BOM lines.
The cap maintains its capacitance within ±10% across that range, with ESR increasing at low temperature. For a satellite power bus that sees -55°C cold soak and 125°C near the output stage, the derating curve must be checked — at -55°C the ESR can triple, reducing ripple current headroom.
2312 case — board layout fit
The 2312 (6032 Metric) case measures 6.00 mm x 3.20 mm with a seated height of 2.80 mm max. This is a standard tantalum footprint; the manufacturer size code is C. The molded body is general purpose — no low-ESR or automotive-grade screening, so for under-hood applications the 125°C rating is the limit, but AEC-Q200 is not claimed here.
