UPH2G181MHD

The UPH2G181MHD is a high‑voltage, miniature aluminum electrolytic capacitor from Nichicon’s UPH series designed for compact power applications. It is a radial‑lead, polarized can capacitor rated for 400 V with a nominal capacitance of 180 µF.

Engineered for use in ballast and general‑purpose high‑voltage circuits, the UPH2G181MHD delivers high ripple capability and extended high‑temperature endurance—providing reliable filtering and energy storage where space is limited.

Key Features

• Capacitance and Voltage: 180 µF nominal capacitance at a rated voltage of 400 V, suitable for high‑voltage DC filtering and energy storage.
• High ripple current: Rated ripple handling of 1.06 A at 120 Hz and 1.59 A at 10 kHz, enabling improved thermal performance under AC bias and switching noise conditions.
• Long high‑temperature life: Load life specified as 2000 hours at 105 °C with DC bias plus rated ripple current applied, delivering endurance in elevated‑temperature environments.
• Temperature range: Operating temperature from −40 °C to +105 °C to cover a wide array of industrial and lighting environments.
• Leakage and dissipation: Leakage current specification follows the formula 0.04CV + 100 µA (measured after 1 minute at 20 °C); tangent of loss angle (tan δ) for 400 V is max. 0.15.
• Package and mounting: Radial lead, can style package with lead spacing 7.5 mm and compact dimensions (L: 4 × D: 1.8 cm), for through‑hole mounting and space‑constrained boards.
• Tolerance and polarity: Capacitance tolerance ±20% and polarized construction for DC applications.
• Environmental compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Ballast and lighting control: High voltage rating and ripple tolerance make this capacitor suitable for ballast circuitry and compact lighting power modules.
• High‑voltage power supplies: Used for DC filtering and energy smoothing in compact high‑voltage supply stages where space and ripple performance are important.
• Industrial electronics: General‑purpose high‑voltage decoupling and energy storage in industrial control equipment operating up to 105 °C.

Unique Advantages

• High voltage capability: 400 V rating enables use in higher‑voltage DC circuits without stacking multiple lower‑voltage parts.
• Compact footprint: Small can size (L: 4 × D: 1.8 cm) and radial leads reduce board area while keeping a through‑hole mounting option.
• Improved ripple handling: Specified ripple currents at both low and high frequencies help manage heating and extend service life under AC bias conditions.
• Extended endurance at temperature: 2000‑hour load life at 105 °C supports long‑running applications in elevated ambient temperatures.
• Measurable electrical stability: Defined limits for tan δ and leakage current provide predictable behavior for filter and smoothing designs.
• RoHS compliant: Meets current RoHS requirements for ease of integration into regulated product lines.
