UPM1V121MPD

The UPM1V121MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series, engineered for high-reliability applications. It delivers 120 µF capacitance at a 35 V rating in a compact φ8 × 15 mm can with 3.5 mm lead spacing.

Designed for demanding environments, the part combines low impedance characteristics and endurance for long-term operation, making it suitable for automotive electronics and other systems requiring stable filtering and decoupling under elevated temperature conditions.

Key Features

• Capacitance and Voltage: 120 µF rated capacitance with a 35 V nominal voltage and tolerance of -20% to +20% for predictable energy storage and filtering.
• Low impedance performance: 140 mΩ impedance and a tanδ (DF) of 0.12 measured at 20°C, 120 Hz, supporting effective ripple attenuation in power circuits.
• Ripple current capability: Rated low-frequency ripple current of 196.1 mA at 120 Hz and high-frequency ripple current of 370 mA at 200 kHz to handle both mains-frequency and switching-frequency ripple components.
• Leakage and polarization: Polarized design with a measured leakage current of 126 µA, suitable for DC power applications where polarity is maintained.
• High-temperature endurance: Specified life of 3000 hours at +105°C, enabling reliable operation in elevated-temperature environments.
• Compact radial package: φ8 × 15 mm can with 3.5 mm lead spacing and radial lead mounting; available in bulk or bag packing for assembly flexibility.
• Compliance and qualification: AEC-Q200 qualified and RoHS compliant, aligning with industry environmental and automotive qualification expectations.

Typical Applications

• Automotive electronics – high-temperature modules: Use in automotive control and power modules where operation across -55°C to +105°C and 3000 h endurance at 105°C are required.
• Automotive – power filtering: Compact radial form factor and 120 µF/35 V rating make it suitable for localized filtering and decoupling in constrained PCB footprints.
• Automotive – reliable long-life designs: AEC-Q200 qualification and specified leakage, ripple, and impedance values support robust performance in long-life vehicle electronics.

Unique Advantages

• Temperature-rated endurance: 3000 hours at +105°C ensures predictable long-term performance in elevated-temperature applications.
• AEC-Q200 qualification: Explicit AEC-Q200 listing supports adoption in automotive-grade designs that require recognized component qualification.
• Compact footprint with adequate capacitance: 120 µF in a φ8 × 15 mm can balances energy density and board-space constraints for compact modules.
• Low impedance and controlled loss angle: 140 mΩ impedance and tanδ 0.12 (20°C, 120 Hz) provide effective ripple suppression and stable AC behavior.
• Dual-frequency ripple capability: Specified ripple currents at both 120 Hz and 200 kHz accommodate systems with mixed-frequency ripple sources.
• RoHS compliant: Conforms to RoHS requirements for environmental compliance in modern product designs.
