The TPSY337M006R0100: The 100 mOhm ESR is the key spec for a sourcing decision: it limits self-heating under ripple current and keeps the capacitor from acting as a low-pass filter that attenuates the very transients it is meant to absorb. On a 6.3 V rail, derate the working voltage by 20% (to ~5 V) for reliability per standard tantalum practice — the 6.3 V rating gives headroom for a 5 V bus.
Rated for -55°C to 125°C operating temperature, this cap spans the full industrial and military temperature envelope. The capacitance and ESR shift across that range — expect capacitance to drop by ~10-15% at -55°C and ESR to rise — but the part is specified to function without derating up to 125°C, unlike commercial-grade tantalums that top out at 85°C. The molded case (Type Molded) and 2917 footprint (7.30mm x 4.30mm, seated height 2.00mm) mean it reflows with standard Pb-free profiles and fits the common 7343 metric land pattern. No special handling beyond standard MSL for molded tantalums.
Active lifecycle — still a current-production line item
Tolerance is ±20%, which is typical for tantalum electrolytics. For a decoupling application this is fine; for a timing or filter circuit, budget the spread or select a tighter-tolerance part from the same series.
