UHW1E680MDD

The UHW1E680MDD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHW series, designed for compact, general-purpose power decoupling and smoothing in electronic assemblies. It delivers 68 µF capacitance at a 25 V rating in a miniature φ5 × 11 mm can with 2 mm lead spacing.

Built for applications that require high ripple handling and reliable operation across a wide ambient range, this part combines low loss (tanδ 0.13 at 20°C, 120 Hz), low leakage, and a long endurance rating for sustained performance in demanding environments.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a rated voltage of 25 V and a tolerance of −20% to +20%.
• Low Loss — Specified tangent of loss angle (tanδ) of 0.13 measured at 20°C, 120 Hz for stable AC performance.
• High Ripple Capability — Low-frequency ripple current of 180 mA at 120 Hz and high-frequency ripple current of 450 mA at 10 kHz to support power rail smoothing and decoupling tasks.
• Low Leakage — Leakage current specified at 17 µA, suitable for circuits where minimal leakage is required.
• Temperature & Endurance — Operating temperature range from −40°C to +105°C with an endurance rating of 7000 hours at 105°C.
• Compact Radial Package — φ5 × 11 mm can with 2 mm lead spacing (±0.5 mm) for space-constrained board layouts; radial lead mounting.
• Packaging Options — Available in Bulk (no terminal forming) and Bag packing to suit assembly and prototyping workflows.
• Environmental — RoHS compliant.
• Lifecycle Status — Product status: End Of Life.

Typical Applications

• Power Supply Filtering — Provides bulk decoupling and smoothing on low-voltage power rails in compact power supplies and DC–DC converters.
• Consumer Electronics — Miniature footprint and high ripple handling make it suitable for small consumer devices where board space is limited.
• Industrial Control Modules — Useful for local decoupling and noise suppression in control electronics operating across a broad temperature range.
• Portable Instruments — Compact size and low leakage are beneficial for battery-powered measurement and instrumentation equipment.

Unique Advantages

• Compact footprint: φ5 × 11 mm can and 2 mm lead spacing allow placement in tight PCB real estate without sacrificing capacitance.
• High ripple tolerance: Specified ripple currents (180 mA at 120 Hz, 450 mA at 10 kHz) support effective smoothing of both low- and high-frequency components.
• Robust temperature performance: −40°C to +105°C operating range and 7000 hours endurance at 105°C provide predictable behavior in elevated ambient conditions.
• Low-loss operation: tanδ of 0.13 (20°C, 120 Hz) helps maintain efficiency in AC and ripple conditions.
• Low leakage: 17 µA leakage current minimizes quiescent loss in sensitive circuits.
• RoHS compliant: Meets environmental directive requirements for restricted substances.
