UBY1J951MHL6

The UBY1J951MHL6 is a miniature, high‑reliability aluminum electrolytic capacitor in a radial lead can, designed for demanding high‑temperature and high‑ripple applications. It is a member of Nichicon’s UBY series and is intended for use where elevated operating temperatures and elevated ripple currents are required.

Targeted market segments include automotive and power electronics applications where AEC‑Q200 qualification, wide temperature range, and high ripple capability are necessary. The part combines 950 µF capacitance at 63 V with a compact φ18 × 20 mm package and robust endurance at high temperature.

Key Features

• Capacitance & Voltage — 950 µF nominal capacitance with tolerance of −20% to +20% and rated voltage of 63 V.
• High‑Temperature Endurance — Rated operating temperature range of −40 °C to +135 °C with specified life of 2000 hours at 135 °C for 63 V units.
• Low Impedance / Loss — Tangent of loss angle (tan δ) of 0.10 measured at 20 °C, 120 Hz for 63 V units, supporting stable performance under AC stress.
• High Ripple Current Capability — Low‑frequency ripple current of 1.26 A at 120 Hz and high‑frequency ripple current of 2.10 A at 100 kHz, enabling effective smoothing in high‑ripple environments.
• Low ESR — Equivalent series resistance of 48 mΩ at 20 °C and 100 kHz for reduced power dissipation and improved thermal performance.
• Leakage Current — Specified leakage current of 1795.5 µA (measured per rated conditions), consistent with the capacitor’s CV characteristic.
• Package & Mounting — Radial lead can, size φ18 × 20 mm with 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant, suited for regulated applications requiring recognized quality standards.

Typical Applications

• Automotive control systems — Designed for automobile control circuits such as electric power steering and direct injection engine drive, where high temperature and ripple tolerance are required.
• High‑temperature power electronics — Use in power modules and circuits operating up to 135 °C that demand sustained ripple handling and stable capacitance.
• Modules requiring AEC‑Q200 qualification — Appropriate for electronic control units and subsystems where AEC‑Q200 qualification is required by the design specification.

Unique Advantages

• High ripple handling: Rated ripple currents of 1.26 A (120 Hz) and 2.10 A (100 kHz) reduce the need for parallel components in high‑ripple designs.
• Compact, high‑capacitance package: 950 µF in a φ18 × 20 mm radial can provides significant capacitance density for space‑constrained assemblies.
• High‑temperature endurance: Qualified for operation up to 135 °C with a 2000‑hour endurance at that temperature, supporting long service life in heated environments.
• Low ESR for thermal efficiency: 48 mΩ ESR at 20 °C / 100 kHz helps minimize self‑heating and improves overall powertrain thermal performance.
• AEC‑Q200 and RoHS compliance: Built to recognized automotive quality standards and environmental compliance for regulated applications.
• Flexible packaging: Available in bulk (no terminal forming) or bag packing to suit assembly and procurement workflows.
