Active production — parametric fit for bulk decoupling
The TPSD686K020R0300: The 300 mOhm ESR (Equivalent Series Resistance) is the key parameter for ripple current handling and self-heating — lower ESR means less internal temperature rise for a given ripple current, which directly affects reliability in high-frequency switching applications.
Temperature range and board-fit considerations
Operating from -55°C to 125°C, this capacitor covers the full industrial temperature envelope and the upper end of automotive under-hood ambient. The molded case construction provides mechanical stability during reflow soldering and resists cracking from board flex, a common failure mode for conformally-coated tantalums. Tape-and-reel packaging supports automated pick-and-place for volume assembly.
Lifecycle and sourcing posture
No pin-compatible second-source is documented, but the D-case 68 µF/20 V parametric is a standard value carried by multiple tantalum manufacturers — a cross-reference search at quote time is straightforward.
