UPM1E122MHD

The UPM1E122MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPM series. It is a radial‑lead, polarized can designed for applications that require significant bulk capacitance and robust performance over a wide temperature range.

Key attributes include a 1200 µF capacitance at 25 V, low impedance (32 mΩ), high ripple current capability, and a long endurance rating of 5000 hours at +105°C—making it suitable for demanding embedded and automotive electronics designs.

Key Features

• Capacitance and Voltage — 1200 µF nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20% for predictable energy storage.
• Low Impedance — 32 mΩ impedance supports fast transient response and stable decoupling in power circuits.
• High Ripple Handling — Low-frequency ripple current of 1.271 A at 120 Hz and high-frequency ripple current of 1.55 A at 200 kHz to manage AC stress in power rails.
• Loss Characteristics — tanδ = 0.14 measured at 20°C and 120 Hz for this 1200 µF unit, indicating controlled dissipation under normal conditions.
• Reliability and Endurance — Rated for 5000 hours at +105°C; life testing and endurance characteristics target long-term stability in elevated-temperature environments.
• Mechanical Package — Compact radial can: diameter φ12.5 × length 25 mm, lead spacing 5 mm (lead spacing tolerance ±0.5 mm), suitable for through‑hole mounting.
• Leakage Current — Specified leakage current of 900 µA for predictable standby losses in power-sensitive designs.
• Compliance & Production — AEC‑Q200 qualified and RoHS compliant; available in bulk or bag packing and in mass production.

Typical Applications

• Automotive Electronics — Suitable for in-vehicle systems that require AEC‑Q200 qualification and wide temperature operation from −55°C to +105°C.
• Power Conditioning — Bulk energy storage and rail decoupling where high ripple currents and low impedance are needed.
• Embedded Power Supplies — Voltage smoothing and reservoir capacitance in PCB through‑hole assemblies using radial lead mounting.
• Industrial Control — Applications requiring reliable long‑term operation at elevated temperatures and sustained ripple stress.

Unique Advantages

• High Capacitance in a Compact Can: 1200 µF in a φ12.5 × 25 mm package delivers substantial energy density for space-constrained designs.
• Designed for Ripple and Transient Loads: Low impedance (32 mΩ) combined with rated ripple currents (1.271 A at 120 Hz, 1.55 A at 200 kHz) helps stabilize power rails under dynamic loads.
• Long Endurance at Elevated Temperature: 5000 hours at +105°C supports extended service life in hot operating environments.
• Automotive-Grade Qualification: AEC‑Q200 qualification and RoHS compliance provide traceable suitability for regulated applications.
• Through-Hole Robustness: Radial lead construction with 5 mm lead spacing and standard can form factor simplifies board-level mounting and replacement.
