UPM1C331MPD

The UPM1C331MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can package from Nichicon’s UPM series. It provides 330 µF capacitance at a 16 V rating with polarized radial leads and compact φ8 × 15 mm dimensions.

Designed for demanding environments, the part combines a wide operating temperature range (−55 °C to 105 °C), AEC-Q200 qualification, and a 3000 hour endurance at 105 °C, making it suitable for electronic modules that require stable bulk energy storage and ripple handling under elevated temperature conditions.

Key Features

• Capacitance and Voltage — 330 µF rated capacitance with a 16 V DC rating and tolerance of −20% to +20%.
• Low Loss — Dissipation factor (tan δ) of 0.16 measured at 20 °C and 120 Hz, supporting efficient operation in power applications.
• Low Impedance — Specified impedance of 120 mΩ to support effective filtering and decoupling.
• Ripple Current Capability — Low-frequency ripple current 263.9 mA at 120 Hz and high-frequency ripple current 455 mA at 200 kHz, enabling stable operation across a range of switching frequencies.
• Leakage Current — Leakage current listed as 158.4 µA, consistent with controlled self-discharge characteristics.
• High Temperature Endurance — Rated life of 3000 hours at 105 °C for reliable performance in elevated-temperature environments.
• Mechanical and Packaging — Radial lead (polar) can with φ8 × 15 mm size, 3.5 mm lead spacing (±0.5 mm tolerance), and available in bulk (no terminal forming) or bag packing.
• Compliance — RoHS compliant and AEC-Q200 qualified.

Typical Applications

• Automotive electronic modules — Suited for in-vehicle electronics where AEC-Q200 qualification and a −55 °C to 105 °C operating window are required.
• Power supply filtering in compact systems — Compact φ8 × 15 mm package and low impedance support reservoir and smoothing tasks in constrained layouts.
• High-temperature electronics — 3000 hour endurance at 105 °C provides design assurance for modules exposed to elevated ambient conditions.

Unique Advantages

• Automotive-grade reliability: AEC-Q200 qualification and specified 3000 h endurance at 105 °C support use in regulated automotive electronic designs.
• Broad temperature range: −55 °C to 105 °C operation enables use across cold-start and high-heat environments.
• Dual-frequency ripple handling: Separate low- and high-frequency ripple current specifications (263.9 mA at 120 Hz and 455 mA at 200 kHz) clarify performance for both line-frequency and switching applications.
• Compact footprint: φ8 × 15 mm can with 3.5 mm lead spacing minimizes board area for space-constrained designs.
• Verified electrical characteristics: Low impedance (120 mΩ), controlled tan δ (0.16), and defined leakage current (158.4 µA) make it straightforward to predict circuit behavior.
• Regulatory compliance: RoHS conformity supports regulatory requirements for modern electronics manufacturing.
