UPH2W680MHD

The UPH2W680MHD is a miniature, high‑voltage aluminum electrolytic capacitor from Nichicon's UPH series. It is a radial‑lead, polarized electrolytic designed for general‑purpose and ballast applications that require compact high‑voltage energy storage.

Key value propositions include a 450 V rating with 68 µF capacitance, high ripple current capability, and long endurance at elevated temperature (2000 hours at 105 °C), providing reliable performance in demanding high‑voltage circuits.

Key Features

• Capacitance & Rated Voltage — 68 µF nominal capacitance with a 450 V rated voltage and capacitance tolerance of −20% to +20%.
• High ripple current — Low frequency ripple current 560 mA (120 Hz) and high frequency ripple current 840 mA (10 kHz) to support higher AC stress conditions.
• Low dissipation factor — tan δ (DF) = 0.20 measured at 20 °C, 120 Hz, for controlled loss characteristics in AC applications.
• Endurance at high temperature — Rated life of 2000 hours at 105 °C under DC bias plus rated ripple current, with defined recovery criteria after test.
• Leakage current — Specified leakage current of 1324 µA (after 1 minute at 20 °C under rated voltage), consistent with high‑voltage miniature construction.
• Compact radial package — Aluminum can, radial lead format with case size φ12.5 × 40 mm and 5.0 mm lead spacing (±0.5 mm), suitable for through‑hole assemblies.
• Environmental compliance & production status — RoHS compliant and in mass production; available packed in bulk (no terminal forming) or bag packing.

Typical Applications

• Ballast circuits — Specifically suited for ballast applications where miniature high‑voltage capacitors with robust ripple handling are required.
• General‑purpose high‑voltage circuits — Used where compact 450 V capacitance is needed for energy storage, filtering, or decoupling in high‑voltage designs.
• Through‑hole assemblies — Radial lead format and 5 mm lead spacing facilitate straightforward placement in through‑hole PCBA environments.

Unique Advantages

• High voltage in a small footprint: 450 V rating in a φ12.5 × 40 mm can enables space‑constrained high‑voltage designs.
• Designed for AC stress: Specified ripple currents (560 mA at 120 Hz, 840 mA at 10 kHz) support higher AC loading compared with lower‑ripple parts.
• Durability at elevated temperature: 2000 hours life at 105 °C provides predictable long‑term behavior under high‑temperature operation.
• Controlled loss and leakage: tan δ = 0.20 (20 °C, 120 Hz) and defined leakage current limit support stable performance in frequency‑sensitive circuits.
• Easy integration: Radial lead package with standard 5 mm spacing and bulk or bag packing simplifies assembly and inventory handling.
• Regulatory compliance: RoHS compliant for use in regulated product lines.
