UPZ2W680MHD

The UPZ2W680MHD is a high-voltage, miniature-sized aluminum electrolytic capacitor from Nichicon's UPZ series. It is a radial-lead, polarized capacitor rated at 450 V with a nominal capacitance of 68 µF and a tolerance of -20% to +20%.

Designed for general-purpose power applications, this capacitor combines compact dimensions (φ16 × 35.5 mm) and a wide operating temperature range (−40°C to 105°C) with defined ripple-handling and endurance characteristics for reliable performance in higher-voltage circuits.

Key Features

• Capacitance & Tolerance — 68 µF nominal capacitance with a tolerance of -20% to +20%, suitable where a defined capacitance range is required.
• High Rated Voltage — 450 V rated voltage for high-voltage DC applications; polarized design for correct polarity usage.
• Ripple Handling — Low-frequency ripple current 490 mA (120 Hz) and high-frequency ripple current 735 mA (10 kHz), supporting both low- and high-frequency ripple conditions.
• Loss Characteristics — Tan δ (dissipation factor) of 0.20 measured at 20°C, 120 Hz for the 450 V rating.
• Leakage Current — Specified leakage current of 1324 µA as provided in the product data.
• Thermal Endurance — Rated for operation from −40°C to 105°C with an endurance rating of 2000 hours at 105°C under rated DC bias plus rated ripple current.
• Compact Radial Package — Can-style radial package, dimensions φ16 × 35.5 mm (L: 3.55 × D: 1.6 cm) with 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• Production Availability — Nichicon UPZ2W680MHD is in mass production.

Typical Applications

• Power-supply filtering — Use where a 450 V rating and 68 µF capacitance are required for smoothing DC bus or high-voltage rails.
• DC link and energy storage — Compact high-voltage capacitor option for localized energy buffering in higher-voltage circuits.
• Industrial power electronics — Suitable for general-purpose industrial control and power modules operating within −40°C to 105°C.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage DC rails without stacking components.
• Compact form factor: φ16 × 35.5 mm size delivers high-voltage performance in a miniature radial-can package for space-constrained designs.
• Defined ripple performance: Specified ripple values at 120 Hz and 10 kHz help designers quantify thermal and lifetime stress under real ripple conditions.
• Wide operating range and endurance: −40°C to 105°C operating range and 2000 hours endurance at 105°C support sustained operation in elevated-temperature environments.
• Clear leakage and loss specs: Documented leakage current and tan δ at the 450 V rating allow predictable loss and self-discharge behavior in designs.
• Production-ready supply: Mass-production status and standard radial-lead packaging simplify procurement and assembly logistics.
