For a 10 V rail, the ripple current rating is approximately 300 mA RMS at 25°C, derating with temperature per the datasheet curve. The B case code (1411 / 3528 Metric) measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. The 0.50 mm pitch between the anode and cathode pads is standard for this case; the recommended land pattern is 1.40 mm pad width with 2.40 mm spacing between pads. Surface-mount assembly on a 2-layer board is straightforward — the B case does not require via-in-pad or thermal vias. The molded body is compatible with reflow profiles per J-STD-020, MSL 3 typical for tantalum chips.","metaTitle":"TAJB685K010K KYOCERA AVX Molded Tantalum Capacitor, 6.8 µF","metaDescription":"TAJB685K010K molded tantalum capacitor, 6.8 µF, 10 V, ±10%, -55°C to 125°C, 3 Ohm ESR.

However, ceramics have different DC bias characteristics — capacitance drops with applied voltage — and do not offer the same ESR profile. Tantalum capacitors provide stable capacitance across the voltage range and a predictable ESR for ripple current handling. Evaluate the circuit's ESR and voltage coefficient requirements before substituting."},{"question":"What is the difference between TAJB685K010K and TAJB685K010J?","answer":"The suffix 'K' and 'J' denote tolerance: 'K' is ±10%, while 'J' is ±5%. Both are the same capacitance (6.8 µF), voltage (10 V), case size (B), and series (TAJ). Choose 'J' when tighter tolerance is needed for timing or filter circuits; 'K' is sufficient for general-purpose decoupling."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJB685K010K","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJB685K010K when reusing this data.
