The ±20% tolerance means the actual capacitance can range from 0.8 µF to 1.2 µF; for a bulk decoupling or RC timing application this is typical, but for a precision filter you would need a tighter tolerance part. The 8 Ohm ESR (equivalent series resistance) is relatively high for a 1 µF capacitor. At high frequencies the ESR dominates impedance, so this part is better suited for bulk storage or low-frequency filtering than for high-speed digital decoupling where you would want sub-ohm ESR. The molded construction gives it good mechanical stability and a low profile — 1.20 mm seated height — which matters in tight board stacks. It can sit in an avionics black box, a downhole tool, or an outdoor telecom enclosure without derating for ambient temperature.","metaTitle":"TAJR105M025RNJ KYOCERA AVX Molded Tantalum Capacitor – 1 µF","metaDescription":"Active KYOCERA AVX TAJR105M025RNJ molded tantalum capacitor. 1 µF, 25 V, ±20% tolerance, 8 Ohm ESR, 0805 package. -55°C to +125°C.
