UBT2A331MHD8

The UBT2A331MHD8 is a radial-lead aluminum electrolytic capacitor designed for high-temperature, heavy-duty duty applications. It provides 330 µF capacitance at a 100 V rating in a compact φ16 × 30.5 mm can with 7.5 mm lead spacing.

Built for demanding environments, this capacitor combines high ripple handling, low impedance and long endurance at elevated temperatures, making it suitable for automotive and other high-reliability electronics where sustained performance at up to +125°C is required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 100 V and capacitance tolerance of −20% to +20%.
• High-temperature endurance — Designed for operation from −40°C to +125°C with a rated life of 5000 hours at 125°C.
• AEC-Q200 qualification — Ratings indicate suitability for automotive-grade projects and other applications requiring AEC-Q200 qualification.
• Ripple current & impedance — Low-frequency ripple current of 1.199 A at 120 Hz and high-frequency ripple current of 1.79 A at 100 kHz, with an impedance of 79 mΩ to support high-demand power filtering.
• Low loss (tan δ) — tanδ of 0.08 measured at 20°C, 120 Hz, helping reduce dissipation in AC conditions.
• Leakage current — Specified leakage current of 990 µA.
• Package & mounting — Radial lead, can-style package; physical dimensions L: 3.05 × D: 1.6 cm with 7.5 mm lead spacing (±0.5 mm).
• Packaging options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.
• RoHS compliant — Conforms to RoHS requirements for restricted substances.

Typical Applications

• Automotive electronics — Suited for vehicle power electronics and electronic control modules where high-temperature endurance and AEC‑Q200 qualification are required.
• High-temperature industrial electronics — Ideal for power supply filtering and decoupling in systems exposed to elevated ambient temperatures.
• Power conversion and filtering — Applies to circuits that demand sustained ripple current handling and low impedance for reliable smoothing under heavy load.

Unique Advantages

• Extended high-temperature life: 5000 hours at 125°C gives predictable longevity in elevated-temperature environments.
• Automotive-grade qualification: AEC-Q200 rating supports integration into automotive designs that require component-level qualification.
• High ripple capability: Combined low- and high-frequency ripple ratings (1.199 A at 120 Hz and 1.79 A at 100 kHz) enable use in demanding power applications.
• Low impedance and loss: 79 mΩ impedance and tanδ 0.08 reduce heating and improve stability in AC and ripple conditions.
• Compact radial can: φ16 × 30.5 mm package with 7.5 mm lead spacing balances board space and ease of through-hole mounting.
• Regulatory compliance: RoHS conformity supports regulatory requirements for restricted substances.
