33 µF, 35 V, 250 mΩ — TPS tantalum for power-rail decoupling
The TPSE336K035R0250: It belongs to the TPS series, a general-purpose line that balances capacitance density with voltage margin for board-level power filtering and decoupling. The 250 mΩ ESR at 100 kHz is the parameter that governs ripple current handling and self-heating — a lower ESR means less power dissipated as heat for a given ripple current, which matters when the capacitor sits near a hot regulator or in a high-frequency switching supply.
Molded case, size code E — footprint and thermal fit
This is a standard tantalum footprint — the pad layout is shared across vendors, so the PCB land pattern is interchangeable with other size-E tantalum capacitors from Kemet or Vishay. The -55°C to +125°C operating range covers industrial and automotive ambient temperature requirements. At 125°C the voltage derating curve applies — the 35 V rating must be reduced per the manufacturer's derating guidelines above 85°C. Molded construction with a compliant termination finish allows surface-mount reflow soldering. The TPS series is rated for standard JEDEC reflow profiles with a peak temperature of 260°C.
Active production — sourcing through distribution
A buyer substituting a different size-E 33 µF 35 V tantalum from another vendor should verify the ESR and temperature rating match the application's derating requirements.
