The molded case construction provides mechanical stability and consistent thermal performance across the -55°C to 125°C operating range. This temperature grade covers both industrial enclosures and automotive under-hood environments without derating. ## ESR and tolerance — what they mean for the BOM 4 Ohm ESR at 100 kHz sets the ripple current handling and high-frequency filtering capability — adequate for bulk decoupling on a 25 V rail where the switching regulator's output ripple is below 50 mV. The ±20% tolerance is standard for tantalum capacitors used in supply bypass and hold-up roles; tighter tolerance is not required for these applications. The 1 µF value at 25 V provides enough charge storage for a typical microcontroller or small FPGA core rail during transient load steps, while the 0805 case keeps the PCB footprint small enough for dense layouts.","metaTitle":"KYOCERA AVX TPSR105M025R4000 Molded Tantalum, 1 µF, 25 V","metaDescription":"KYOCERA AVX TPSR105M025R4000 molded tantalum capacitor, 1 µF ±20%, 25 V, 4 Ohm ESR, 0805 case. -55 to +125°C.
