The TPSE336K025R0100 is a 33 µF molded tantalum capacitor in the TPS series from KYOCERA AVX, rated at 25 V with a 100 mOhm ESR. That ESR figure is the key spec for bulk decoupling — it determines the ripple current handling and the voltage ripple under load.
Operating from -55°C to +125°C, this capacitor covers the full industrial temperature envelope and extends into the lower end of military-grade thermal requirements. The manufacturer size code E confirms the case dimensions. Surface-mount assembly with the molded package means the part withstands typical reflow soldering without cracking, provided the moisture sensitivity level (MSL) rating is observed during storage. The ±10% tolerance on the 33 µF value is standard for tantalum electrolytics and sufficient for most decoupling and filtering roles.
The TPS series is a general-purpose tantalum line, so compliance documentation (RoHS, REACH) is standard from KYOCERA AVX. No UL or IEC certification is typically issued for discrete tantalum capacitors of this class.
