UBC1V331MNS1MS

The UBC1V331MNS1MS is a chip‑type aluminum electrolytic capacitor designed for surface‑mount assembly and demanding thermal and mechanical environments. With a 330 µF capacitance at 35 V, AEC‑Q200 rating, and an operating range from −55°C to 150°C, it targets applications that require sustained performance under high temperature and vibration.

Its core value proposition is dependable high‑temperature endurance and robust ripple handling in a compact SMD can package, backed by Nichicon's UBC series design emphasis on long life and vibration resistance.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 35 V and tolerance of −20% to 20% for predictable bulk energy storage.
• High‑Temperature Endurance — Rated for continuous operation from −55°C to 150°C with life/endurance specified at 1000 hours at 150°C.
• Ripple Performance — Low‑frequency ripple capability of 435.5 mA (120 Hz) and high‑frequency ripple capability of 650 mA (10 kHz) to support power rail smoothing in elevated‑temperature environments.
• Electrical Quality — Tangent of loss angle (tanδ) of 0.14 (measured at 20°C, 120 Hz) and measured leakage current of 346.5 µA for controlled dissipation and standby loss.
• Mechanical & Mounting — Chip‑type aluminum can in a surface‑mount package (case: Radial, Can - SMD), size Ø12.5 × 13.5 mm, and vibration resistant construction for mechanically demanding assemblies.
• Assembly & Packaging — Supplied in embossed carrier taping for automated pick‑and‑place and reflow processes.
• Standards & Compliance — AEC‑Q200 rated and RoHS compliant, aligning with qualification expectations for rugged applications.

Typical Applications

• Automotive electronics — Suited for automobile electronics where heavy‑duty service is required; AEC‑Q200 qualification and −55°C to 150°C rating address harsh under‑hood and vehicle control environments.
• High‑temperature power filtering — Bulk smoothing and decoupling on power rails operating at elevated temperatures, supported by 330 µF capacitance and specified ripple current ratings.
• Vibration‑prone modules — Vibration resistant chip construction and SMD can package make it appropriate for assemblies exposed to mechanical stress and vibration.
• Compact SMD designs — Ø12.5 × 13.5 mm footprint and embossed carrier taping streamline placement in space‑constrained PCB layouts that require high-temperature reliability.

Unique Advantages

• Proven high‑temperature reliability: 1000 hours endurance at 150°C provides a measurable baseline for long‑life operation in elevated‑temperature systems.
• Automotive‑grade qualification: AEC‑Q200 rating supports use in applications that require recognized component qualification for demanding environments.
• Robust ripple handling: Specified ripple current at both low and high frequencies (435.5 mA @ 120 Hz, 650 mA @ 10 kHz) helps maintain stable power rails under dynamic loads.
• Compact SMD can with vibration resistance: Enables automated assembly while retaining mechanical stability in shock and vibration conditions.
• Controlled electrical characteristics: Low tanδ (0.14 at 20°C, 120 Hz) and specified leakage current support predictable performance in power and filtering circuits.
• RoHS compliant supply chain: Environmental compliance for global manufacturing requirements.
