UPH2G121MHD

The UPH2G121MHD from Nichicon is a miniature, radial‑lead aluminum electrolytic capacitor in the UPH series designed for high‑voltage, high‑ripple applications. It delivers 120 µF capacitance at a 400 V rating in a φ16 × 35.5 mm can with 7.5 mm lead spacing.

Designed for general‑purpose and ballast use, the UPH2G121MHD combines high ripple handling, long endurance and wide operating temperature range for demanding power‑electronics environments.

Key Features

• Rated Capacitance and Voltage — 120 µF nominal capacitance at 400 V DC, with capacitance tolerance ±20% (–20%~20%).
• High Ripple Capability — Rated low‑frequency ripple current 800 mA (120 Hz) and high‑frequency ripple current 1.2 A (10 kHz), supporting applications with significant AC ripple.
• Loss Characteristics — tan δ (DF) max 0.15 measured at 20°C, 120 Hz for stable dissipation behavior under rated conditions.
• Leakage Current — Specified leakage current up to 2020 µA (measured after 1 minute at 20°C under rated voltage condition as per series specification method).
• Long Endurance — Load life rated at 2000 hours at 105°C with specified limits on capacitance change, dissipation factor and leakage current after test.
• Robust Environmental Range — Operating temperature range –40°C to +105°C; RoHS compliant.
• Package and Mounting — Radial lead, polarized aluminum can (φ16 × 35.5 mm) with 7.5 mm lead spacing; supplied bulk/no terminal forming or bag packing.

Typical Applications

• Ballasts — Specified by the manufacturer as suited for ballast applications where high‑voltage, compact electrolytic capacitors are required.
• General‑purpose power electronics — Acts as a high‑voltage smoothing or energy‑storage element in equipment that requires 400 V rated polarized capacitors with strong ripple handling.
• High‑temperature environments — Suitable for designs that require continuous operation up to 105°C with a 2000‑hour endurance specification.

Unique Advantages

• High voltage in a miniature package: 400 V rating in a φ16 × 35.5 mm can provides high DC capability without large board footprint.
• Designed for ripple‑intensive use: Specified ripple currents of 800 mA (120 Hz) and 1.2 A (10 kHz) address both low‑ and high‑frequency ripple demands.
• Predictable dissipation behavior: Low tan δ (0.15 at 20°C, 120 Hz) supports thermal and loss budgeting in tight designs.
• Durability at elevated temperature: 2000 hours endurance at 105°C gives a clear lifecycle expectation for high‑temperature deployments.
• Compliance and materials: RoHS compliant construction aligns with environmental requirements for contemporary equipment.
