UBX1K330MPL

The UBX1K330MPL is a miniature, high‑reliability aluminum electrolytic capacitor from Nichicon’s UBX series. It is a radial‑lead, polar capacitor specified at 33 µF and 80 V, designed for demanding high‑temperature environments.

Targeted at heavy‑duty electronics, the UBX1K330MPL delivers stable capacitance and endurance up to +150°C with AEC‑Q200 qualification and RoHS compliance, making it suitable for systems that require compact, durable power decoupling or smoothing at elevated temperatures.

Key Features

• Capacitance and Voltage — 33 µF nominal capacitance with a tolerance of −20% to +20%, rated for 80 V operation.
• High‑Temperature Endurance — Operating temperature range from −55°C to +150°C and specified endurance of 1000 hours at 150°C.
• Low Loss — Tangent of loss angle (tanδ) of 0.08 (measured at 20°C, 120 Hz for 80 V), supporting efficient energy handling.
• Ripple Current Capability — Low‑frequency ripple current 281.4 mA at 120 Hz and high‑frequency ripple current 420 mA at 100 kHz, suitable for AC ripple suppression across frequency ranges.
• Leakage Current — Specified leakage current of 79.2 µA (after 1 minute at rated voltage, 20°C), aiding predictable bias performance.
• Package and Mounting — Compact radial can: diameter φ10 mm × length 12.5 mm, lead spacing 5.0 mm (tolerance ±0.5 mm); radial lead mounting for through‑hole PCB assembly.
• Compliance and Quality — AEC‑Q200 rated and RoHS compliant, aligning with high‑reliability automotive and industrial manufacturing requirements.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to suit production handling preferences.

Typical Applications

• Automotive electronics — Power supply smoothing and decoupling in electronic control modules and other vehicle systems where components must tolerate elevated temperatures.
• High‑temperature power circuits — Local energy storage and ripple suppression inside power assemblies that operate continuously near +150°C.
• Compact through‑hole designs — Applications requiring a small radial can (φ10 × 12.5 mm) and 5 mm lead spacing for robust PCB mounting and serviceability.

Unique Advantages

• High temperature capability: Rated to −55°C to +150°C with 1000 h endurance at 150°C, enabling reliable operation in thermally demanding environments.
• Automotive‑grade qualification: AEC‑Q200 rating supports deployment in automotive and similarly stringent applications requiring documented component quality.
• Frequency‑spanning ripple performance: Defined ripple current values at 120 Hz and 100 kHz provide predictable behavior across both low and high frequency power disturbances.
• Compact radial package: φ10 mm can with 5 mm lead spacing offers a small footprint for space‑constrained through‑hole designs while retaining robust mechanical mounting.
• Predictable electrical loss and leakage: Low tanδ (0.08) and specified leakage current (79.2 µA) help maintain stable filtering and bias characteristics over temperature.
• Compliance and supply options: RoHS compliance plus bulk or bag packing choices simplify integration into manufacturing processes.
