UPH2G680MHD

The UPH2G680MHD is a high‑voltage, miniature-sized aluminum electrolytic capacitor from Nichicon's UPH series. It is a polarized, radial‑lead can designed for general-purpose and ballast applications that require a compact 400 V capacitor with high ripple handling and extended high‑temperature life.

This part delivers 68 µF capacitance at 400 V with a compact 12.5 × 35.5 mm case (L: 3.55 × D: 1.25 cm) and a 5.0 mm lead spacing, making it suitable for space‑constrained high‑voltage assemblies where sustained ripple performance and long operating life are required.

Key Features

• Electrical Performance — 68 µF rated capacitance at 400 V with ±20% tolerance (at 120 Hz, 20 °C), polarized for DC applications.
• High Ripple Capability — Rated ripple currents of 540 mArms at 120 Hz and 810 mArms at 100 kHz support demanding AC ripple conditions common in ballast and power converter circuits.
• Long High‑Temperature Life — Load life specified at 2000 hours at 105 °C under rated DC bias plus rated ripple current, providing predictable endurance in elevated temperature environments.
• Low Losses — tan δ (dissipation factor) specified at a maximum of 0.15 for 400 V, helping to limit heating and power loss in high‑voltage applications.
• Leakage Current Specified — Leakage current listed as 1188 µA (measured at 20 °C after 1 minute), enabling straightforward design margin calculations for power and safety considerations.
• Compact Radial Can Package — Radial lead, can‑type package with 5.0 mm lead spacing and a small footprint (12.5 × 35.5 mm), suited to through‑hole layouts requiring robust mechanical mounting.
• Wide Operating Temperature — Rated for –40 °C to +105 °C operation, covering a broad range of industrial ambient conditions.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Ballast Circuits — Designed and specified as suited for ballast applications where sustained high ripple and high voltage are required.
• High‑Voltage Power Filters — Use for DC smoothing and high‑voltage filtering in general‑purpose power supply designs.
• Industrial Power Electronics — Fits compact, through‑hole assemblies that require durable high‑voltage capacitors with predictable life at elevated temperatures.

Unique Advantages

• High ripple tolerance: Specified ripple currents at both 120 Hz and 100 kHz provide design confidence across a range of switching and mains frequencies.
• Extended elevated‑temperature life: 2000 hours at 105 °C under rated conditions enables reliable operation in high‑stress thermal environments.
• Compact high‑voltage form factor: 12.5 × 35.5 mm can and 5.0 mm lead spacing reduce board area while delivering 400 V capability for space‑constrained designs.
• Measurable loss and leakage characteristics: tan δ (max. 0.15 at 400 V) and a defined leakage current (1188 µA) simplify thermal and leakage budgeting in system designs.
• RoHS compliance: Meets current RoHS directive requirements for restricted substances, supporting regulatory needs for commercial products.
