UCP2W680MHD

The UCP2W680MHD is a radial‑lead, high‑voltage aluminum electrolytic capacitor from Nichicon’s UCP series. It is a miniature, high‑reliability type designed for general‑purpose applications that require a compact form factor, long endurance and stable electrical performance at elevated voltages.

With a rated voltage of 450 V, 68 µF capacitance, and a guaranteed 10,000‑hour life at 105 °C, this part targets designs that need high‑voltage smoothing and long‑term stability in a small radial can package.

Key Features

• Capacitance and Voltage — 68 µF nominal capacitance at a rated voltage of 450 V with ±20% tolerance (−20% to +20%).
• Long Endurance — Rated for 10,000 hours at 105 °C under DC bias plus rated ripple current, with post‑test limits of capacitance within ±20% and leakage current ≤ initial specified value.
• Low‑loss Characteristics — tanδ (loss tangent) specified at 0.24 (measured at 20 °C, 120 Hz) for predictable dissipation behavior.
• Ripple Current Capability — Low‑frequency ripple current 560 mA at 120 Hz and high‑frequency ripple current 840 mA at 10 kHz, enabling effective ripple handling across frequencies.
• Leakage Current — Specified leakage current of 1324 µA (measured after 1 minute at 20 °C), stated per product data.
• Wide Temperature Range — Operates from −40 °C to 105 °C for broad environmental tolerance.
• Compact Mechanical Profile — Can size φ12.5 × 40 mm with 5 mm lead spacing (lead spacing tolerance ±0.5 mm) and radial lead mounting for through‑hole assembly.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and handling.

Typical Applications

• General‑purpose high‑voltage circuits — Suited for designers needing a compact, radial‑lead electrolytic capacitor rated to 450 V for general power‑electronic use.
• High‑temperature endurance requirements — Appropriate where long life at elevated temperature (10,000 h at 105 °C) is a priority.
• Compact PCB through‑hole designs — Fits applications that require a miniature can (φ12.5 × 40 mm) and standard 5 mm lead spacing for radial mounting.

Unique Advantages

• High‑voltage capability: 450 V rating allows use in circuits requiring elevated DC voltage handling without increasing package size.
• Long operational life: 10,000 hours at 105 °C delivers predictable lifespan and reduces replacement frequency in demanding thermal environments.
• Frequency‑spanning ripple performance: Specified ripple currents at 120 Hz (560 mA) and 10 kHz (840 mA) support stable ripple handling across both low and high frequency components.
• Compact radial form factor: φ12.5 × 40 mm can with 5 mm lead spacing provides a space‑efficient through‑hole solution for legacy and industrial PCBs.
• Measured loss and leakage specifications: tanδ = 0.24 and defined leakage current enable predictable dissipation and insulation performance for reliable designs.
• Flexible packaging: Bulk or bag packing options help accommodate different assembly and inventory workflows.
