The TPSE477M010R0045: The 45 mOhm ESR keeps ripple voltage low in switching regulator output filters — at 1 A ripple current the ripple voltage is 45 mV, well within typical load regulation budgets.
Temperature range and board integration
Surface mount mounting with tape and reel packaging supports automated pick-and-place. The molded case provides mechanical stability during reflow and resists cracking from board flex better than conformally coated parts.
The TPS series is a general-purpose molded tantalum line. The ±20% tolerance is standard for this capacitor class; derating to 50% of rated voltage is recommended for reliable operation in low-impedance circuits.
