UBX1K331MHL

The UBX1K331MHL is a radial-lead aluminum electrolytic capacitor from Nichicon’s UBX series, designed for high-temperature, heavy-duty applications. It combines a laminated can construction with AEC-Q200 rating and a 2000-hour endurance at 150°C to deliver stable capacitance and ripple handling in demanding environments.

With a rated capacitance of 330 µF at 80 V, low-loss characteristics (tanδ 0.08 at 20°C, 120 Hz), and defined ripple current specifications across low and high frequencies, this part is optimized for applications that require robust thermal performance and reliable long-term operation.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance with ±20% tolerance and an 80 V rated voltage for mid-voltage system use.
• High-temperature Endurance — Operates across −55°C to +150°C and specified for 2000 hours at 150°C, supporting sustained performance in elevated-temperature environments.
• Low Loss — Tangent of loss angle (tanδ) of 0.08 measured at 20°C, 120 Hz, supporting efficient energy storage with controlled dissipation.
• Ripple Current Capability — Rated low-frequency ripple current of 991.6 mA at 120 Hz and high-frequency ripple current of 1.48 A at 100 kHz for handling AC stress on power rails.
• Leakage Current — Specified leakage current of 792 µA, useful for predicting standby and bias loss in system designs.
• Mechanical and Mounting — Radial-lead can with dimensions φ16 × 30.5 mm (D × L), lead spacing 7.5 mm (±0.5 mm), and standard bulk or bag packing (no terminal forming).
• Reliability & Compliance — AEC-Q200 rated for automotive-grade reliability and RoHS compliant.
• Polarized Device — Polarized aluminum electrolytic construction; intended for correct polarity installation in DC applications.

Typical Applications

• Automotive electronics — Intended for automotive systems where AEC-Q200 qualification and extended high-temperature endurance are required.
• High-temperature power modules — Suited to modules and assemblies operating near +150°C where long-life capacitive performance is needed.
• Power rail smoothing — Used where defined ripple-current capability and low dissipation (tanδ) are important for stable DC bus performance.

Unique Advantages

• High-temperature rating: Rated to −55°C to +150°C with 2000-hour endurance at 150°C, enabling deployment in elevated-temperature environments.
• AEC-Q200 qualification: Provides an automotive-grade reliability benchmark for designs requiring established component-level qualification.
• Strong ripple handling: Specified ripple currents at both low and high frequencies allow predictable AC stress management in power circuits.
• Compact radial form factor: φ16 × 30.5 mm can with 7.5 mm lead spacing balances capacitance density with straightforward through-hole mounting.
• Controlled loss and leakage: Low tanδ and specified leakage current simplify thermal and power-loss budgeting in system-level designs.
• Production availability: Listed as mass production, supporting stable supply for volume deployments.
