UPM1E331MPD

The UPM1E331MPD is an aluminum electrolytic capacitor from Nichicon's UPM series designed for low impedance and high reliability. It is a radial-lead, polarized capacitor with a rated capacitance of 330 µF at 25 V and a capacitance tolerance of ±20%.

Engineered for demanding environments, this component offers a wide operating temperature range of −55°C to +105°C, a 3000‑hour life at 105°C for its case size, and AEC‑Q200 qualification for automotive use.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 25 V with ±20% tolerance, suitable for decoupling and energy-storage roles within its voltage rating.
• Low Impedance — Specified impedance of 85 mΩ supports effective ripple smoothing and low-loss performance in power circuits.
• Loss Characteristics — tanδ of 0.14 (measured at 120 Hz, 20°C) for predictable AC loss behavior.
• Leakage Current — Rated leakage current of 247.5 µA, enabling controlled standby and bias current profiles.
• Ripple Current Capability — Rated ripple current of 353.8 mA at 120 Hz and 610 mA at 200 kHz for handling low- and high-frequency ripple components.
• Reliability & Lifetime — 3000 hours endurance at +105°C (for this case size) to address long-term thermal stress requirements.
• Mechanical & Packaging — Compact φ8 × 20 mm can, radial lead package with 3.5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Environmental Compliance & Qualification — RoHS compliant and AEC‑Q200 qualified, supporting regulatory and automotive reliability needs.

Typical Applications

• Automotive power systems — Energy storage and smoothing in vehicle electronic power supplies where AEC‑Q200 qualification and −55°C to +105°C operation are required.
• ECU and control modules — Bulk decoupling and ripple filtering in control electronics that demand long life and stable capacitance under thermal stress.
• On-board power conditioning — Low-impedance filtering of low- and high-frequency ripple as indicated by the specified ripple current ratings at 120 Hz and 200 kHz.

Unique Advantages

• Designed for automotive reliability — AEC‑Q200 qualification and a rated operating range down to −55°C support deployment in vehicle electronics.
• Thermal endurance — 3000‑hour life at 105°C for the specified case size provides predictable long-term performance in high-temperature environments.
• Compact radial package — φ8 × 20 mm can with 3.5 mm lead spacing enables space-efficient board placement while keeping through-hole mounting simplicity.
• Measured ripple performance — Separate ripple current ratings at 120 Hz and 200 kHz allow designers to assess suitability across low- and high-frequency regimes.
• Controlled leakage and dissipation — Specified leakage current and tanδ give engineers quantitative parameters for power-budget and thermal modeling.
• Regulatory compliance — RoHS compliance supports environmental and supply-chain requirements.
