The 0805 (2012 Metric) case code is a standard footprint for automated assembly — compatible with most pick-and-place lines and reflow profiles used for tantalum capacitors. ## ESR and ripple current — the 20 Ohm ceiling The 20 Ohm ESR (Equivalent Series Resistance) is on the higher side for a 1 µF tantalum capacitor. This limits the ripple current capability — for a 20 V rail, the maximum ripple current at 100 kHz is roughly 70 mA RMS before self-heating becomes a concern. Use this part in low-ripple decoupling or timing circuits rather than high-frequency switching regulator outputs where lower ESR is needed.","metaTitle":"TAJR105K020A KYOCERA AVX Molded Tantalum Capacitor 1 µF 20","metaDescription":"TAJR105K020A is an active KYOCERA AVX TAJ series molded tantalum capacitor, 1 µF ±10%, 20 V rated, 0805 package, -55°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Specialty Capacitors"],"specifications":{"Mfr":"KYOCERA AVX","Type":"Molded","Series":"TAJ","Package":"Tape & Reel (TR)","Features":"General Purpose","Tolerance":"±10%","Capacitance":"1 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"0805 (2012 Metric)","Product Status":"Active","Voltage - Rated":"20 V","lifecycle_stage":"unknown","Lifetime @ Temp.":"-","Size / Dimension":"0.081\\\" L x 0.051\\\" W (2.05mm x 1.30mm)","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-55°C ~ 125°C","Manufacturer Size Code":"R","ESR (Equivalent Series Resistance)":"20Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJR105K020A/alternatives.json"},"ai":{"faq":[{"question":"Is TAJR105K020A RoHS compliant?","answer":"The TAJ series from KYOCERA AVX is generally RoHS compliant, but the evidence does not list a specific RoHS status for this order code.
