UCX1V821MNQ1MS

The UCX1V821MNQ1MS is a chip‑type aluminum electrolytic capacitor engineered for high‑temperature applications up to +135°C. Built in a surface‑mount radial can (SMD) package and compatible with carrier‑tape automated placement, it delivers bulk capacitance and temperature endurance where elevated operating temperatures and reliable long‑term performance are required.

Targeted use cases include automotive and high‑temperature electronics where a combination of high capacitance (820 µF), 35 V rating, low ESR and AEC‑Q200 qualification provide measurable design value for power filtering, bulk energy storage and decoupling at elevated temperatures.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance at a 35 V rated voltage, suitable for bulk energy storage and smoothing in power systems.
• High Temperature Performance: Specified for operation from −40 °C to +135 °C with endurance tested to 2000 hours at 135 °C.
• Low ESR Characterization: ESR specified at 50 mΩ measured at 100 kHz, with ESR characterization included after −40 °C testing to validate low‑temperature behavior.
• Ripple Current Capability: Rated ripple current of 600 mA at 120 Hz and 1.2 A at 10 kHz for handling AC ripple in power circuits.
• Automated Assembly Friendly: Chip type design compatible with automatic mounting machines fed by carrier tape; surface‑mount radial can (SMD) package simplifies high‑volume PCB assembly.
• Reliability & Compliance: AEC‑Q200 qualified and RoHS compliant, supporting designs that require industry reliability qualification and environmental conformity.
• Compact Footprint: Package dimensions L: 1.65 × D: 1.6 cm with recommended land pattern (L: 1.63 × W: 1.63 cm) for PCB layout and placement.

Typical Applications

• Automotive Electronics: Bulk filtering and energy storage in automotive control modules and power systems where AEC‑Q200 qualification and +135 °C endurance are required.
• High‑Temperature Power Supplies: Smoothing and decoupling in power converters and regulators operating in elevated ambient temperatures.
• Industrial Power Modules: Bulk capacitance for motor controllers and industrial power assemblies that require long endurance at high temperature.
• Automated SMT Production: Surface‑mount chip package designed for carrier‑tape placement in high‑volume manufacturing flows.

Unique Advantages

• High‑temperature endurance: Rated to +135 °C with 2000 hours endurance at that temperature, enabling confident deployment in hot environments.
• AEC‑Q200 qualification: Presence of AEC‑Q200 rating supports use in designs requiring recognized automotive reliability standards.
• Low ESR at wide temperature range: ESR specified at 50 mΩ (100 kHz) and measured after −40 °C testing, giving predictable impedance behavior across temperature extremes.
• Robust ripple handling: Dual ripple current ratings (600 mA at 120 Hz, 1.2 A at 10 kHz) address both low‑ and high‑frequency ripple in power systems.
• SMT‑ready package: Chip‑type SMD radial can with carrier‑tape compatibility streamlines automated assembly and reduces BOM complexity for high‑volume builds.
• Environmental conformity: RoHS compliance supports regulatory requirements for modern electronics manufacturing.
