UPA1V122MHD

The UPA1V122MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for power applications. It delivers 1.2 mF capacitance at a 35 V rating in a compact φ12.5 × 25 mm case with 5 mm lead spacing.

Part of Nichicon’s UPA series — engineered for low impedance and elevated ripple handling — this capacitor is suitable for switching power supplies and general-purpose power circuits that require long endurance and a wide operating temperature range.

Key Features

• Capacitance & Voltage: 1.2 mF (1200 µF) nominal capacitance with a rated voltage of 35 V and tolerance of -20% to +20%.
• Low Impedance: Specified impedance of 44 mΩ supports stable performance under dynamic loads.
• High Ripple Capability: Low-frequency ripple current 1.938 A (120 Hz) and high-frequency ripple current 2.28 A (10 kHz) for demanding switching environments.
• Dielectric Loss (tan δ): tan δ = 0.12 measured at 20°C, 120 Hz, providing conservative dissipation characteristics for design.
• Leakage Current: Leakage current specified at 1260 µA after application of rated voltage (20°C, 1 minute), consistent with the capacitor’s capacitance and voltage.
• Temperature & Endurance: Rated for -55°C to +105°C with a life/endurance rating of 5000 hours at 105°C.
• Compact Radial Package: φ12.5 × 25 mm can, radial leads with 5.0 mm lead spacing; available in bulk or bag packing.
• Regulatory Compliance: RoHS compliant.

Typical Applications

• Switching Power Supplies: Designed for use in switching regulator output stages where low impedance and elevated ripple current capacity are needed.
• General-Purpose Power Systems: Suits a broad range of power applications requiring 1200 µF at 35 V with long-term endurance.
• High-Temperature Environments: Applications that operate across -55°C to +105°C and require a capacitor rated for 5000 hours at 105°C.
• Compact Radial-Lead Designs: Ideal for space-constrained boards that require a radial can with 5 mm lead spacing.

Unique Advantages

• High Ripple Handling: Measured ripple currents of 1.938 A (120 Hz) and 2.28 A (10 kHz) let designers manage AC stress without oversizing the capacitor bank.
• Low Effective Series Impedance: 44 mΩ impedance supports stable voltage hold-up and reduces ripple voltage on power rails.
• Long Endurance at Elevated Temperature: 5000 hours at 105°C provides predictable lifetime for high-temperature applications.
• Compact Footprint: φ12.5 × 25 mm case and 5 mm lead spacing help minimize board area while retaining substantial capacitance.
• Clear Performance Parameters: Specified tan δ and leakage current values enable accurate thermal and loss budgeting in designs.
• RoHS Compliant: Meets RoHS requirements for use in compliant product programs.
