Product details

470 µF at 10 V — bulk decoupling for power rails

The TPSE477M010R0100: The E case code (2917 / 7343 metric footprint) is the standard large-body tantalum size for this capacitance-voltage combination.

ESR and temperature — the real selection axes

For a 100 kHz buck converter output, the I²R loss at 1 A ripple is 0.1 W — well within the 125°C rated limit, but the ESR doubles at -55°C, so a cold-start design must budget higher ripple voltage at low temperature. The molded construction (Type Molded) resists moisture ingress better than conformally-coated tantalums, which matters for boards that see condensation or washdown residue. ±20% tolerance is standard for tantalum electrolytics — the capacitance at 10 V bias will measure between 376 µF and 564 µF at 25°C.

Active production — no last-time-buy pressure

The part is sourced through independent distribution channels.

Frequently asked questions

Where can I buy TPSE477M010R0100 and get a price?

The TPSE477M010R0100 is available to order through independent distribution.

What is the ESR of TPSE477M010R0100 and why does it matter?

The ESR is 100 mOhm. This is the resistive loss inside the capacitor — lower ESR means less heat generation at a given ripple current and better transient response when the load steps. For a 470 µF cap on a 10 V rail, 100 mOhm is a standard value that balances cost and performance.

What is the case size and footprint for TPSE477M010R0100?

The case is the E code, which is the 2917 (7343 metric) size — 7.30 mm long by 4.30 mm wide with a seated height of 4.30 mm. This is the standard large tantalum footprint and is compatible with generic 2917 land patterns.
