UPM2A390MPD

The UPM2A390MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPM series, engineered for low impedance and high reliability. It provides 39 µF capacitance at a 100 V rating in a compact φ8 × 20 mm can with 3.5 mm lead spacing, intended for demanding electronics where a robust, high-voltage decoupling or energy-storage capacitor is required.

Designed for long-term operation across a wide temperature range (−55 °C to +105 °C) and qualified to AEC-Q200, this part targets applications that demand voltage headroom, temperature endurance, and proven lifecycle performance (3000 hours at 105 °C for this case size).

Key Features

• Capacitance & Voltage — 39 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, providing high-voltage energy storage in a small package.
• Low Impedance Performance — Specified impedance of 330 mΩ and tan δ of 0.08 (measured at 20 °C, 120 Hz), supporting stable AC performance and reduced ripple voltage.
• Ripple Current Capability — Low-frequency ripple current 142.8 mA at 120 Hz and high-frequency ripple current 280 mA at 200 kHz, suitable for circuits with continuous or switching ripple loading.
• Leakage Current — Rated leakage current of 117 µA, measured after one minute at rated voltage and 20 °C, helping to minimize standby losses.
• Temperature & Endurance — Operating range from −55 °C to +105 °C with a load-life endurance of 3000 hours at 105 °C for the specified case size.
• Package & Mounting — Radial-lead can (φ8 × 20 mm) with 3.5 mm lead spacing (±0.5 mm), available in bulk/no terminal forming or bag packing for flexible assembly handling.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant, aligning with automotive-grade reliability and environmental requirements.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and −55 °C to +105 °C rating make the UPM2A390MPD suitable for electronic control modules and other automotive subsystems requiring reliable high-voltage capacitors.
• High-Voltage Power Circuits — 100 V rating supports use in power-supply stages and systems that require elevated voltage handling in a compact radial package.
• Harsh-Environment Equipment — Extended temperature range and 3000-hour endurance at 105 °C provide durability for equipment operating in wide temperature or continuous-load conditions.

Unique Advantages

• High-Voltage Capability: 100 V rating enables designs with higher DC bus voltages without moving to larger form factors.
• Compact Radial Form Factor: φ8 × 20 mm can with 3.5 mm lead spacing delivers a small footprint for space-constrained boards while maintaining useful capacitance.
• Measured Low Impedance: 330 mΩ impedance and tan δ = 0.08 (20 °C, 120 Hz) help reduce ripple and improve stability in AC-loaded circuits.
• Proven Endurance: 3000 hours at 105 °C for this case size provides predictable lifecycle behavior in high-temperature operating conditions.
• AEC-Q200 Qualification: Explicitly supports applications requiring automotive-grade component qualification.
• Packaging Flexibility: Available in bulk/no terminal forming or bag packing to accommodate different assembly and inventory workflows.
