UPM1H331MPD

The UPM1H331MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPM series, engineered for low impedance and long-term reliability. It provides 330 µF capacitance at a 50 V rating in a compact φ10 × 30.5 mm can with 5 mm lead spacing, intended for demanding automotive and high-reliability power applications.

Key design attributes include low impedance (55 mΩ), a rated operating temperature range of -55 °C to +105 °C, AEC-Q200 qualification, and a 5000-hour load life at 105 °C—making it suitable where sustained high-temperature endurance and stable electrical performance are required.

Key Features

• Electrical Performance — 330 µF capacitance at 50 V with ±20% tolerance and a tangent of loss angle (tan δ) of 0.10, delivering predictable AC and transient behavior.
• Low Impedance — Rated impedance of 55 mΩ supports lower voltage drop under ripple and transient currents.
• High Ripple Capability — Ripple currents of 577.1 mA at 120 Hz and 995 mA at 200 kHz enable robust filtering in high-frequency and low-frequency environments.
• Long Life and High Temperature Endurance — 5000 hours lifetime at 105 °C under rated load conditions, supporting extended service in elevated-temperature installations.
• Automotive-Grade Qualification — AEC-Q200 rated and specified for automotive applications as listed in the product data.
• Mechanical and Mounting — Radial lead, can-style package with φ10 × 30.5 mm dimensions and 5 mm lead spacing for through-hole mounting and straightforward PCB placement.
• Leakage and Loss — Specified leakage current of 495 µA and low loss characteristics to maintain energy efficiency and reliability in DC-biased circuits.
• Regulatory Compliance — RoHS compliant per provided product information.

Typical Applications

• Automotive Electronics — Suitable for automotive ECUs and vehicle power systems where a 50 V, 330 µF capacitor with AEC-Q200 qualification is required.
• On-board Power Filtering — Use for smoothing and decoupling in 50 V power rails, leveraging low impedance and high ripple current ratings.
• High-Temperature Power Modules — Designed for modules and assemblies that operate up to +105 °C and require sustained life under load.

Unique Advantages

• Validated High-Temperature Endurance: 5000-hour load life at 105 °C provides predictable aging and long-term stability in hot environments.
• Low Impedance Design: 55 mΩ impedance reduces voltage drop and improves transient response in power conditioning applications.
• Strong Ripple Handling: Ripple current specs for both 120 Hz and 200 kHz broaden applicability across low- and high-frequency filtering tasks.
• Automotive-Grade Qualification: AEC-Q200 rating supports integration into automotive system designs where qualification is required.
• Compact Through-Hole Package: φ10 × 30.5 mm can with 5 mm lead spacing offers a space-efficient radial solution for PCB-mounted power sections.
• Regulatory Compliance: RoHS compliance aligns with environmental and regulatory requirements for mainstream electronic assemblies.
