UHW1K680MPD

The UHW1K680MPD is a radial lead, polarized aluminum electrolytic capacitor in Nichicon’s UHW series, delivering 68 µF at 80 V in a compact φ8×15L package. Designed for general-purpose power applications, it combines a small footprint with high ripple-current capability and extended high-temperature endurance.

Key attributes include low impedance at higher frequencies, a wide operating temperature range from –40 °C to 105 °C, and 11,000 hours endurance at 105 °C, making it suitable where reliable power smoothing and decoupling are required in constrained spaces.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance.
• Compact Radial Can — φ8×15L package (L: 1.5 × D: 0.8 cm) with radial lead mounting and 3.5 mm lead spacing (±0.5 mm).
• High Ripple Current — Low-frequency ripple current 492 mA (120 Hz) and high-frequency ripple current 1.23 A (10 kHz), suited for demanding AC ripple conditions.
• Low Impedance and Loss — Impedance of 900 mΩ and tanδ (loss tangent) of 0.09 measured at 20 °C, 120 Hz for efficient performance at operating frequencies.
• Leakage Current — Low leakage current specified at 54.4 µA.
• Wide Temperature & Long Life — Operates from –40 °C to 105 °C with an endurance rating of 11,000 hours at 105 °C.
• Regulatory — RoHS compliant; product is in mass production and available in bulk/bag packing (no terminal forming).
• Clear Identification — Marked with white lettering on a black sleeve for easy visual identification.

Typical Applications

• Power supply smoothing — Bulk and output filter smoothing where 80 V rating and 68 µF capacitance are required for voltage stabilization.
• Decoupling and ripple suppression — Local decoupling for DC rails and suppression of AC ripple, leveraging the capacitor’s high ripple-current capability and low impedance.
• Compact power modules — Use in space-constrained modules that require a small φ8×15L footprint with robust thermal endurance up to 105 °C.

Unique Advantages

• High ripple handling: Specified ripple currents at 120 Hz and 10 kHz allow effective suppression of both low- and high-frequency ripple components.
• Compact footprint: φ8×15L size delivers 68 µF capacitance without occupying large board area, enabling denser power designs.
• Long-term stability at elevated temperature: Endurance of 11,000 hours at 105 °C supports long service life in hot operating environments.
• Low loss and impedance: tanδ of 0.09 and 900 mΩ impedance help minimize energy dissipation and voltage drop under AC conditions.
• Simple assembly: Radial lead format with defined lead spacing simplifies through-hole placement and manual or automated insertion.
• RoHS compliant and production-ready: Environmentally compliant construction and mass-production availability for reliable supply.
