UPT2E121MHD

The UPT2E121MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPT series. It is a radial-lead, polarized capacitor specified at 120 µF and 250 V designed for general-purpose use and applications that demand high ripple endurance.

Engineered for long life and elevated temperature operation, the UPT2E121MHD delivers high ripple current capability and stable performance across –40 °C to +105 °C, making it suitable for ballast applications and other high-ripple circuits.

Key Features

• Capacitance and Voltage — 120 µF capacitance rated at 250 V, with a capacitance tolerance of -20% to +20% (measured at 120 Hz, 20 °C).
• High Ripple Current — Rated low-frequency ripple current of 530 mA at 120 Hz and high-frequency ripple current of 848 mA at 10 kHz, enabling robust performance in circuits with significant AC ripple.
• Loss Characteristics — tanδ specified at 0.12 (measurement condition: 20 °C, 120 Hz), providing a defined dissipation factor for predictable AC behavior.
• Long Life Endurance — Life rating of 5000 hours at 105 °C under DC bias plus rated ripple current, with specified limits for capacitance change, tanδ, and leakage current after endurance testing.
• Temperature Range — Operating temperature range from –40 °C to +105 °C supports elevated-temperature use cases.
• Compact Radial Package — Case diameter φ12.5 mm × length 40 mm with 5.0 mm lead spacing (lead spacing tolerance ±0.5 mm); radial can package for through-hole mounting.
• Leakage Current — Specified leakage current of 1810 µA (measured condition: after 2 minutes at 20 °C with rated voltage).
• RoHS Compliance and Packaging — RoHS-compliant; available in bulk (no terminal forming) or bag packing for flexible procurement and assembly options.

Typical Applications

• Ballast circuits — Suited for ballast application where high ripple current handling is required.
• High-ripple power circuits — Use for smoothing and ripple filtering in power circuits that demand elevated ripple endurance, leveraging the specified low- and high-frequency ripple current ratings.
• Elevated-temperature designs — Fits designs requiring long service life at up to 105 °C, supported by a 5000-hour endurance specification.

Unique Advantages

• High ripple capability: Rated ripple currents of 530 mA (120 Hz) and 848 mA (10 kHz) enable reliable performance in AC-stressed circuits.
• Long-term reliability: 5000-hour endurance at 105 °C assures sustained electrical characteristics under prolonged elevated-temperature operation.
• Predictable dissipation: tanδ of 0.12 (120 Hz, 20 °C) provides a clear dissipation factor for thermal and loss budgeting in designs.
• Compact radial form factor: φ12.5×40 mm can with 5.0 mm lead spacing delivers a space-efficient, through-hole solution for PCB assembly.
• RoHS compliant supply options: Available in bulk or bag packing and compliant with RoHS requirements for streamlined manufacturing and regulatory alignment.
