UBX1H331MHL

The UBX1H331MHL is a radial-lead aluminum electrolytic capacitor in Nichicon’s UBX series, offering 330 µF capacitance at a 50 V rating. It is designed for high-temperature, long-life applications and is supplied in a compact φ12.5 × 20 mm can with 5.0 mm lead spacing.

Targeted at demanding electronics — including automotive systems — this part combines a +150°C operating range, AEC-Q200 rating, and robust ripple-current capability to support power filtering and energy stabilization in heavy-duty environments.

Key Features

• Capacitance & Tolerance — 330 µF nominal capacitance with a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Voltage Rating — Rated for 50 V DC operation.
• High-Temperature Endurance — Rated for operation from −55°C to +150°C with an endurance life of 1000 hours at 150°C.
• Ripple Current Performance — Low-frequency ripple current: 515.9 mA (120 Hz); high-frequency ripple current: 770 mA (100 kHz), enabling effective AC smoothing across a wide frequency range.
• Low Loss — tan δ (dissipation factor) of 0.10 (measured at 20°C, 120 Hz) for controlled ESR-related losses.
• Leakage Current — Specified leakage current of 495 µA (after 1 minute at 20°C), supporting predictable bias behavior.
• Package & Mounting — Radial lead (can) package, size φ12.5 × 20 mm, lead spacing 5.0 mm (±0.5 mm), supplied bulk or in bag packing with no terminal forming.
• Automotive-Grade & Compliance — AEC-Q200 rated and RoHS compliant, suitable for applications requiring recognized component-level screening.
• Polarized Design — Standard polarized aluminum electrolytic construction for DC decoupling and energy storage functions.
• Production Status — Mass production availability for supply continuity.

Typical Applications

• Automotive Electronics — Suited for automobile electronics and heavy-duty in-vehicle modules where +150°C capability and AEC-Q200 qualification are required.
• Power Supply Filtering — Provides bulk capacitance and ripple-current handling for DC link smoothing and power-stabilizing stages in high-temperature environments.
• Industrial Control — Use in industrial and heavy-duty control electronics that demand long endurance at elevated temperatures.

Unique Advantages

• High-Temperature Reliability: Rated −55°C to +150°C with a 1000-hour endurance at 150°C, enabling use in thermally demanding designs.
• Automotive-Grade Screening: AEC-Q200 rating offers component-level assurance for automotive and similarly stringent applications.
• Compact, Serviceable Package: φ12.5 × 20 mm radial can with 5.0 mm lead spacing balances board density with through-hole robustness.
• Wide-Frequency Ripple Capability: Specified ripple currents at both 120 Hz and 100 kHz (515.9 mA and 770 mA) support filtering across low and high-frequency domains.
• Predictable Electrical Behavior: Low tan δ (0.10 at 20°C, 120 Hz) and specified leakage current (495 µA) give predictable ESR and bias characteristics for power designs.
• Regulatory Compliance: RoHS compliance ensures conformance with current restricted-substance requirements.
