UBY1V302MHL

The UBY1V302MHL from Nichicon is a miniature radial lead aluminum electrolytic capacitor in the UBY series, designed for high-temperature and high-ripple environments. It delivers 3,000 µF capacitance at 35 V in a compact φ16 × 25 mm can with 7.5 mm lead spacing.

Engineered for automotive and other demanding applications, this AEC‑Q200 qualified, RoHS‑compliant part offers high ripple current capability, low ESR, and extended endurance up to 135°C, making it suitable for power supply smoothing and high-stress power-electronics roles.

Key Features

• Capacitance and Voltage — 3,000 µF nominal capacitance with a rated voltage of 35 V and tolerance of −20% to +20%.
• High Temperature Endurance — Rated operating temperature range −40°C to 135°C with a life/endurance specification of 3,000 hours at 135°C.
• High Ripple Current — Low‑frequency ripple current of 2.152 A (120 Hz) and high‑frequency ripple current of 2.87 A (100 kHz) to support heavy AC loading.
• Low ESR — Equivalent series resistance of 26 mΩ measured at 20°C/100 kHz, supporting lower AC impedance in power circuits.
• Loss Tangent (tan δ) — Dissipation factor of 0.16 (measured condition: 20°C, 120 Hz) appropriate for large-capacitance, high-temperature use.
• Package and Mounting — Radial lead (can) package, size φ16 × 25 mm, lead spacing 7.5 mm, bulk or bag packing options available.
• Reliability and Compliance — AEC‑Q200 qualified and RoHS compliant for use in regulated, reliability‑focused designs.

Typical Applications

• Automotive control systems — Designed for automotive applications where high temperature and ripple handling are required, including power electronics used in vehicle control modules.
• Power supply smoothing — Bulk energy storage and smoothing in DC power rails subjected to high ripple currents and elevated ambient temperatures.
• High‑stress power electronics — Use in modules and assemblies that demand low ESR and sustained performance at up to 135°C.

Unique Advantages

• High ripple handling capability: Specified ripple currents of 2.152 A (120 Hz) and 2.87 A (100 kHz) enable reliable operation under significant AC stress.
• Extended high‑temperature life: Rated for 3,000 hours at 135°C, supporting designs that operate in elevated temperature environments.
• Low AC impedance: 26 mΩ ESR at 100 kHz reduces voltage ripple and improves performance in high-frequency power circuits.
• AEC‑Q200 qualification: Provides an added level of design assurance for automotive and other reliability‑sensitive applications.
• Compact radial can form factor: φ16 × 25 mm size with 7.5 mm lead spacing simplifies board placement while offering high capacitance density.
• Compliance and availability: RoHS compliant and listed as mass production, suitable for volume deployment.
