UAQ2D680MHD

The UAQ2D680MHD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon’s UAQ series. It provides 68 µF nominal capacitance at a 200 V rating with a polarized radial-can package and is intended for general-purpose electronic applications.

Key design attributes include high ripple-current capability, a wide operating temperature range, and series-level safety measures for abnormal voltage conditions, delivering reliable smoothing and energy-storage performance in through-hole assemblies.

Key Features

• Electrical — 68 µF, 200 V: Nominal capacitance 68 µF with a rated voltage of 200 V and capacitance tolerance −20% to 20%.
• Ripple current capability: Low-frequency ripple current 250 mA (120 Hz) and high-frequency ripple current 400 mA (10 kHz).
• Loss angle (tan δ): tan δ specified at 0.15 (measurement condition: 20°C, 120 Hz).
• Wide temperature range: Rated for −40°C to +105°C operation.
• Endurance: Specified life of 2000 hours at 105°C under rated conditions.
• Safety features: UAQ series improvements for permissible abnormal voltage and a pressure-relief vent to reduce hazardous failure modes.
• Mechanical — compact radial can: Case Ø12.5 × 25 mm, lead spacing 5.0 mm (±0.5 mm), radial-lead mounting.
• Leakage current: Specified leakage current 644 µA.
• Compliance & packaging: RoHS compliant; supplied in bulk (no terminal forming) or bag packing.

Typical Applications

• General-purpose power filtering: Smoothing and decoupling where 68 µF at 200 V is required and polarized radial components are appropriate.
• High-ripple circuits: Circuits with elevated ripple conditions benefit from the UAQ2D680MHD’s rated ripple currents at both low and high frequency.
• Thermally stressed environments: Designs that require operation across −40°C to +105°C and sustained performance demonstrated by a 2000-hour endurance rating at 105°C.

Unique Advantages

• 200 V rating: Supports higher-voltage circuit requirements without changing package type.
• Elevated ripple handling: 250 mA (120 Hz) and 400 mA (10 kHz) ratings reduce internal heating in ripple-rich power stages.
• Wide operating temperature and endurance: −40°C to +105°C range with 2000 hours endurance at 105°C for sustained performance under thermal stress.
• Measured stability: tan δ limited to 0.15 at 20°C/120 Hz to help characterize loss behavior in design.
• Built-in safety measures: Series-level improvements for abnormal voltage tolerance and a pressure-relief vent to mitigate hazardous outcomes.
• Compact radial form factor: Ø12.5 × 25 mm can and 5 mm lead spacing for straightforward through-hole placement.
• RoHS compliant: Meets RoHS requirements for environmentally conscious designs.
