680 µF at 2.5 V with 35 mOhm ESR — the power rail decoupling choice
The TPSE687M002R0035: This combination of high capacitance and low ESR makes it a strong candidate for bulk decoupling on low-voltage core rails — think 1.8 V or 1.2 V processor and FPGA supplies where the ripple current demand can exceed what a ceramic MLCC bank alone handles without excessive parallel count. The 35 mOhm ESR is the headline figure for this part: it directly governs the ripple current rating and the capacitor's ability to absorb transient load steps without excessive voltage droop. For a 2.5 V rail, a 680 µF cap with 35 mOhm ESR delivers a self-resonant frequency around 100 kHz — right in the switching regulator band for most POL converters.
Temperature range and case size — fit for industrial and automotive environments
Rated for -55°C to 125°C operation, the TPSE687M002R0035 covers the full industrial temperature envelope and the under-hood automotive ambient requirement. The molded construction (Type: Molded) provides a robust encapsulation that resists mechanical stress during reflow and board flex. This is the standard package for TPS series parts and mates with the standard 2917 solder pad geometry.
Active lifecycle — no obsolescence risk for production builds
The TPS series is a standard catalog line from KYOCERA AVX with broad distribution coverage.
