68 µF, 20 V, 200 mOhm — the ESR drives the ripple rating
The TPSE686M020R0200: For a 68 µF part in the 2917 case, this ESR translates to roughly 1.2 A ripple current capability before the internal temperature rise exceeds 10°C — check the derating curve for your operating frequency. The -55°C to 125°C operating range covers the full industrial temperature envelope, but MnO2 tantalum capacitors require voltage derating above 85°C. At 125°C, the applied voltage should not exceed 50% of the 20 V rating — 10 V maximum — to stay within the safe operating area and avoid field failures from dielectric breakdown. This package gives the lowest ESR per capacitance in the TPS series, but the 4.30 mm height may conflict with low-profile board stacking — verify the keep-out zone above the capacitor before layout.
Active lifecycle — standard distribution sourcing
The molded construction (Type Molded) uses a conformally coated MnO2 tantalum element, not a dipped or polymer cathode. This is the standard construction for the TPS series, offering a balance of ESR, leakage, and surge current capability for general-purpose decoupling and hold-up applications.
