The 22 µF value covers most local decoupling needs for an MCU or small FPGA core supply. ## Temperature grade and deployment fit The molded construction and 1206 package handle the thermal cycling without cracking the body, though the ESR will rise at the cold end. Availability confirmed at RFQ time.","metaTitle":"TAJS226K004RNJ KYOCERA AVX TAJ Series 22 µF Molded Tantalum","metaDescription":"TAJS226K004RNJ: KYOCERA AVX TAJ series molded tantalum capacitor, 22 µF, 4 V, ±10%, 1206 package, -55°C to 125°C, 3.5 Ohm ESR.
