UHV1C681MPD6

The UHV1C681MPD6 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon's UHV series, configured as a radial-lead can. It provides 680 µF capacitance at a 16 V rating with a compact φ8 × 15 mm case and 3.5 mm lead spacing.

Designed for general-purpose power and decoupling applications, this part delivers low impedance and elevated ripple-current capability in a small footprint, with an endurance rating of 6000 hours at 105°C and RoHS compliance.

Key Features

• Capacitance and Voltage — 680 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of −20% to +20% for predictable energy storage.
• Low Frequency and High Frequency Ripple Handling — Rated ripple current: 798 mA at 120 Hz (low frequency) and 1.33 A at 100 kHz (high frequency), enabling stable performance across common power-system frequencies.
• Low Impedance — Specified impedance of 143 mΩ to support low-voltage-drop decoupling and improved high-frequency performance.
• Dissipation Factor (tan δ) — tan δ of 0.15 measured at 20°C, 120 Hz, providing a quantifiable dissipation characteristic for AC applications.
• Leakage Current — Typical leakage current listed as 108.8 µA, useful for estimating standby losses and biasing requirements.
• High Endurance — Life rating of 6000 hours at 105°C (with DC bias plus rated ripple current), supporting robust operation in elevated-temperature environments.
• Compact Radial Package — φ8 × 15 mm can, radial lead mounting with 3.5 mm lead spacing (±0.5 mm), and Pb‑free leadwire/sleeve configuration (PD), available in bulk or bag packing.
• Operating Temperature Range — −40°C to +105°C to cover common industrial and consumer operating conditions.
• Regulatory — RoHS compliant.

Typical Applications

• Power supply smoothing — Bulk energy storage and ripple filtering on low-voltage rails where compact size and high ripple capability are required.
• Decoupling and local energy reservoir — High-frequency decoupling for power converters and switching regulators benefiting from low impedance at high frequency.
• Industrial and consumer electronics — General-purpose use in control boards, power modules, and small form-factor equipment that require extended endurance at elevated temperatures.

Unique Advantages

• High ripple-current capability: Rated ripple currents of 798 mA (120 Hz) and 1.33 A (100 kHz) reduce temperature rise and support sustained AC stress in power circuits.
• Low impedance: 143 mΩ impedance helps minimize voltage drop and improves transient response when used for decoupling and smoothing.
• Compact radial form factor: φ8 × 15 mm can with 3.5 mm lead spacing provides a small footprint for through-hole designs while retaining substantial capacitance.
• Extended high-temperature endurance: 6000 hours at 105°C supports longer service life in thermally demanding applications.
• Quantified electrical characteristics: Specified tan δ (0.15 at 20°C/120 Hz) and measured leakage current (108.8 µA) enable accurate thermal and bias budgeting in designs.
• RoHS compliance and packaging options: Environmental compliance and availability in bulk or bag packing simplify procurement and assembly flows.
