UPA1V102MHD

The UPA1V102MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UPA series, optimized for high-reliability power applications. It delivers 1000 µF at a 35 V rating in a compact φ12.5 × 20 mm can, targeting switching power supplies and general-purpose power filtering where low impedance, high ripple handling and extended endurance are required.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance with a rated voltage of 35 V and a tolerance of -20% to +20%.
• Low Impedance — Rated impedance of 58 mΩ, supporting stable decoupling and bulk energy storage in compact layouts.
• High Ripple Current Capability — Low-frequency ripple current 1.417 A (120 Hz) and high-frequency ripple current 1.89 A (100 kHz), suited for demanding switching environments.
• Electrical Losses — tan δ (DF) of 0.12 measured at 20°C, 120 Hz (35 V rating), indicating controlled dissipation for power applications.
• Leakage Current — Specified leakage current 1050 µA (equivalent to 0.03CV after 1 minute at 20°C), for predictable bias behavior.
• High Temperature Endurance — 5000 hours life at 105°C when operated under rated conditions, enabling long-term stability in elevated-temperature designs.
• Robust Operating Range — Temperature range from -55°C to +105°C for use across a wide set of environmental conditions.
• Compact Radial Package — φ12.5 × 20 mm can with 5 mm lead spacing (±0.5 mm), shipped in bulk or bag packing; radial-lead mounting for through-hole assemblies.
• RoHS Compliant — Meets RoHS requirements as specified in the product data.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and high ripple current capacity improve regulation and thermal performance.
• General Purpose Power Filtering — Decoupling and energy storage on power rails in industrial and commercial electronics that require durable, long-life capacitors.
• High-Temperature Electronics — Circuits exposed to elevated ambient temperatures benefitting from 5000-hour endurance at 105°C.

Unique Advantages

• High ripple-handling capability: Rated ripple currents of 1.417 A (120 Hz) and 1.89 A (100 kHz) reduce voltage ripple and heat buildup in switching circuits.
• Low real-world impedance: 58 mΩ impedance supports tighter voltage regulation and improved transient response in compact designs.
• Compact footprint: φ12.5 × 20 mm can and 5 mm lead spacing enable high-density through-hole placement without sacrificing capacitance.
• Extended elevated-temperature life: 5000 hours at 105°C provides predictable long-term performance in demanding thermal environments.
• Controlled dissipation: tan δ of 0.12 at 20°C, 120 Hz (35 V) helps designers estimate losses and thermal impact accurately.
• Compliance and packaging flexibility: RoHS compliance and availability in bulk or bag packing support production and procurement workflows.
