UHD1C681MPD

The UHD1C681MPD is an aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic power applications. It delivers 680 µF of capacitance at a 16 V rating with a compact φ8 × 20 mm package and radial lead mounting.

Part of Nichicon’s UHD series, this device emphasizes low impedance at high frequency and high ripple-current capability, making it suitable where compact bulk capacitance and reliable ripple handling are required across a wide temperature range.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a tolerance of −20% to +20% at the rated 16 V.
• Low impedance / High ripple capability — Designed for lower impedance at high frequency; rated ripple currents of 937.5 mA at 120 Hz and 1.25 A at 100 kHz reduce heating under AC/ripple stress.
• Leakage and dissipation — Specified leakage current of 108.8 µA (measured after 2 minutes at 20°C) and a tangent of loss angle (tanδ) of 0.16 at 20°C, 120 Hz for the 16 V rating.
• Endurance & temperature range — Rated life of 3000 hours at 105°C; operational temperature range from −40°C to +105°C.
• Mechanical and packaging — Radial lead can with dimensions φ8 × 20L mm, lead spacing 3.5 mm (±0.5 mm tolerance); available in Bulk (no terminal forming) or Bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• Power supply filtering and smoothing — Bulk capacitance and rated ripple current make this capacitor suitable for reducing voltage ripple on DC rails in general-purpose electronics.
• DC-DC converter output stages — Low impedance at high frequency and 1.25 A ripple capability at 100 kHz support decoupling and energy storage on converter outputs.
• Industrial control electronics — Wide −40°C to +105°C operating range and 3000-hour endurance at 105°C provide stability in elevated-temperature control environments.
• Space-constrained consumer and embedded designs — 680 µF capacitance in a compact φ8 × 20 mm radial can suits applications where board area is limited.

Unique Advantages

• Compact high-capacitance footprint: 680 µF in a φ8 × 20 mm can reduces board area while providing substantial bulk capacitance.
• High ripple-handling capability: Rated ripple currents of 937.5 mA at 120 Hz and 1.25 A at 100 kHz lower stress on the part and the surrounding circuitry under AC-loaded conditions.
• Low loss at rated conditions: tanδ of 0.16 at 16 V, 20°C, 120 Hz indicates controlled dissipation for power applications.
• Robust thermal endurance: 3000 hours at 105°C supports continuous operation in higher-temperature environments.
• Industry-compliant material set: RoHS compliance simplifies regulatory management for assemblies.
• Procurement-ready availability: Mass-production status and standard Bulk/Bag packaging options support volume sourcing and assembly processes.
