330 µF bulk tantalum for 3.3 V rails
The TPSF337M004R0200: The 200 mOhm ESR governs the ripple current the part can handle before self-heating shifts the capacitance; at 100 kHz the impedance is dominated by this resistance, not the capacitive reactance.
Temperature range and tolerance
Operating from -55°C to 125°C, this capacitor covers the full industrial temperature envelope and extends into under-hood automotive ambient zones. The ±20% tolerance means the minimum capacitance at end-of-life and at temperature extremes is 264 µF — enough headroom for most bulk decoupling budgets where the downstream regulator's loop stability depends on a minimum output capacitance.
Case size and board fit
The molded construction provides mechanical stability during reflow and resists cracking from board flex better than conformally-coated tantalum chips. Tape and reel packaging supports automated pick-and-place at volume.
Active lifecycle — no obsolescence risk
Listed as Active by KYOCERA AVX, the TPSF337M004R0200 carries no last-time-buy or end-of-life notice. This is a standard-production tantalum capacitor suitable for both new designs and sustaining BOM positions.
