UPT2G101MHD

The UPT2G101MHD is a polarized aluminum electrolytic capacitor from Nichicon's UPT series, specified for high‑voltage, high‑ripple applications in a compact radial‑lead can. With a 100 µF capacitance at a 400 V rating, it targets general‑purpose electronic circuits that require high ripple handling and extended life under elevated temperature.

Designed for radial lead mounting, the capacitor combines high ripple current capability, long endurance at elevated temperature, and RoHS compliance to support sustained operation in demanding AC and DC environments.

Key Features

• Capacitance and Voltage: 100 µF capacitance rated at 400 V, suitable for high‑voltage applications where compact energy storage is required.
• High Ripple Current: Rated ripple current of 580 mA at 120 Hz and 928 mA at 10 kHz, enabling effective handling of AC ripple and high‑frequency stress.
• Long Life and Endurance: Qualified for 5000 hours at 105°C under D.C. bias plus rated ripple current; after test the capacitance remains within ±20% and leakage remains at or below initial specification.
• Temperature Range: Operational from −40°C to +105°C, supporting a wide range of ambient conditions.
• Package and Mounting: Radial lead, can‑style package with 7.5 mm lead spacing and compact physical footprint (L: 3.55 × D: 1.6 cm), for through‑hole assembly.
• Electrical Characteristics: Capacitance tolerance ±20% (at 120 Hz, 20°C); tan δ (loss tangent) for 400 V specified at 0.15 (max) per datasheet series limits.
• Leakage Current Specified: Per series datasheet, leakage after 2 minutes at 20°C is specified as ≤ 0.06CV + 10 µA, providing a measurable leakage baseline for designs.
• Regulatory Compliance: RoHS compliant, aligning with restricted substance requirements.

Typical Applications

• Ballast Circuits: Suited for ballast applications where elevated ripple current performance is required, as noted in the product series documentation.
• General‑Purpose Power Electronics: Use in general‑purpose electronic circuits that require compact, high‑voltage capacitance with sustained ripple handling.
• High‑Frequency Ripple Environments: Suitable where significant ripple at higher frequencies is present, supported by the 10 kHz ripple current rating and frequency coefficients in the series datasheet.

Unique Advantages

• High ripple tolerance: Explicit ripple current ratings (580 mA at 120 Hz; 928 mA at 10 kHz) let designers specify the capacitor for applications with substantial AC content.
• Extended elevated‑temperature life: 5000 hours at 105°C under rated conditions provides predictable endurance for thermal‑stress applications.
• Compact radial can footprint: Small physical dimensions (L: 3.55 × D: 1.6 cm) and 7.5 mm lead spacing enable space‑conscious through‑hole designs.
• Documented electrical baselines: Series datasheet provides quantifiable leakage current formula and tan δ limits to support engineering verification.
• Wide operating range: −40°C to +105°C operation accommodates a broad set of ambient environments.
• RoHS compliance: Meets restricted‑substance requirements for modern production environments.
