UBX1A332MHL

The UBX1A332MHL is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UBX high‑reliability series. It provides 3300 µF capacitance at a 10 V rating in a compact φ18 × 35.5 mm laminated can designed for heavy‑duty, high‑temperature use.

Engineered for applications that demand elevated temperature endurance and sustained ripple capability, this AEC‑Q200 rated, RoHS‑compliant capacitor targets automotive and other harsh‑environment power electronics where long life and stable performance are required.

Key Features

• Capacitance and Voltage: 3300 µF (3.3 mF) rated at 10 V with a tolerance of −20% to +20%, delivering bulk storage for power rails and decoupling in compact designs.
• High‑Temperature Endurance: Operating range −55°C to +150°C with a rated lifetime of 2000 hours at 150°C, suitable for sustained high‑temperature environments.
• Reliability & Automotive Grade: AEC‑Q200 listed construction and laminated case design; the series is described as suited for automobile electronics requiring heavy‑duty service.
• Ripple Handling & Loss Characteristics: Low‑frequency ripple current 804 mA at 120 Hz and high‑frequency ripple current 1.2 A at 100 kHz; tangent of loss angle (tan δ) 0.24 at 20°C, 120 Hz (measured at 10 V).
• Leakage Current: Specified leakage current 990 µA.
• Package & Mounting: Radial lead, polarized aluminum can (φ18 × 35.5 mm) with 7.5 mm lead spacing (±0.5 mm). Available in bulk or bag packing (no terminal forming).
• Regulatory: RoHS compliant.

Typical Applications

• Automotive electronics: Designed for high‑temperature, heavy‑duty automotive systems where AEC‑Q200 qualification and long life at elevated temperatures are required.
• Power supply smoothing: Bulk capacitance and high ripple ratings make it suitable for smoothing and energy storage on power rails in demanding environments.
• High‑temperature power modules: Suited for power modules and assemblies operating at elevated ambient temperatures up to +150°C.

Unique Advantages

• Extended high‑temperature capability: Rated to −55°C to +150°C with a 2000‑hour endurance at 150°C, enabling reliable operation in harsh thermal conditions.
• Automotive‑oriented qualification: AEC‑Q200 listing and explicit suitability for automobile electronics supports integration into vehicle systems requiring automotive‑grade components.
• High ripple tolerance: 804 mA at 120 Hz and 1.2 A at 100 kHz ripple ratings address both low‑ and high‑frequency ripple demands in power designs.
• Compact radial package: φ18 × 35.5 mm can with 7.5 mm lead spacing provides a small footprint for high‑capacitance requirements in through‑hole assemblies.
• Measured electrical characteristics: Specified tan δ (0.24 at 20°C, 120 Hz, 10 V) and defined leakage current (990 µA) give predictable behavior for design validation.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.
