Bulk decoupling for low-voltage rails — 1500 µF at 2.5 V with 30 mΩ ESR
The TPSV158M002R0030: That ESR figure is the key spec for bulk decoupling: it determines the ripple-current handling and the voltage ripple across the capacitor under load transients. A 30 mΩ ESR at 1500 µF means the capacitor can absorb high-frequency ripple without excessive self-heating, making it a strong fit for the output stage of a low-voltage, high-current DC-DC converter or for smoothing the supply rail of a power-hungry ASIC or FPGA core. The ±20% tolerance is standard for tantalum electrolytics of this capacitance range; the actual capacitance will vary with temperature and DC bias, but the ESR is the dominant parameter for filtering performance.
Temperature range and deployment context
Rated for operation from -55°C to 125°C, this capacitor spans the full industrial temperature range and reaches into the automotive under-hood band. The molded construction and the TPS series' established reliability make it suitable for applications where the ambient temperature near the power supply can exceed 85°C, such as in engine control units, base-station power amplifiers, or industrial motor drives.
