UPA1A122MPD6

The UPA1A122MPD6 from Nichicon is a radial lead aluminum electrolytic capacitor delivering 1200 µF of capacitance at a 10 V rating. It is a miniature, low-impedance, high-reliability solution designed for general-purpose power filtering and switching power supply applications.

Engineered for compact power stages, the part combines high ripple-current capability, wide operating temperature range (–55°C to 105°C) and extended endurance (4000 hours at 105°C) in a φ10 × 16 mm radial can with 5 mm lead spacing.

Key Features

• Capacitance & Voltage: 1.2 mF (1200 µF) rated at 10 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Low impedance: Specified impedance of 98 mΩ to help reduce voltage ripple in power circuits.
• High ripple-current capability: Rated for 1.054 A at 120 Hz (low frequency) and 1.24 A at 10 kHz (high frequency), enabling robust performance in switching stages.
• Loss factor (tan δ): tanδ = 0.19 (measured at 20°C, 120 Hz, 10 V).
• Leakage current: Specified leakage current of 360 µA.
• Temperature & endurance: Operating range –55°C to 105°C with a rated life of 4000 hours at 105°C under specified conditions.
• Package & mounting: Radial, can-style package (φ10 × 16L mm) with 5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Compliance: RoHS compliant.

Typical Applications

• Switching power supplies: Bulk smoothing and output filtering where high ripple current and low impedance are required.
• DC/DC converters: Energy storage and decoupling in compact power modules and regulator output stages.
• Industrial control electronics: General-purpose power filtering across a –55°C to 105°C operating range.
• Consumer power modules: Bulk decoupling and ripple suppression in compact, through-hole designs.

Unique Advantages

• Compact high-capacitance footprint: 1200 µF in a φ10 × 16 mm can minimizes board area for bulk-storage needs.
• High ripple handling: Measured ripple-current ratings at 120 Hz and 10 kHz support demanding switching stages and reduce thermal stress.
• Low impedance: 98 mΩ impedance helps deliver lower voltage ripple and improved dynamic response in power circuits.
• Extended thermal endurance: 4000 hours at 105°C provides predictable ageing characteristics for elevated-temperature applications.
• Through-hole implementation: Radial lead package with 5 mm spacing supports straightforward mounting and serviceability in a wide range of assemblies.
• Regulatory compliance: RoHS status supports use in designs targeting RoHS-conformant supply chains.
