UHV0J682MHD

The UHV0J682MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHV series, engineered for general-purpose power applications requiring high ripple capability and low impedance at higher frequencies. Its 6.8 mF capacitance at a 6.3 V rating, compact φ12.5 × 35.5 mm can, and long endurance make it suited for designs where sustained ripple handling, thermal endurance, and compact size matter.

Key Features

• Capacitance and Voltage: 6.8 mF (6800 µF) nominal capacitance with a rated voltage of 6.3 V and tolerance of -20% to +20%.
• Low impedance: Rated impedance of 29 mΩ supports lower AC voltage drop and improved decoupling performance at higher frequencies.
• High ripple current capability: Low-frequency ripple current 3.336 A (120 Hz) and high-frequency ripple current 3.925 A (100 kHz) for robust AC loading performance.
• Loss and leakage: Measured tanδ (DF) 0.31 at 20°C, 120 Hz, and leakage current specified as 428.4 µA.
• Endurance and temperature range: Rated endurance 6000 hours at 105°C; operating temperature range -40°C to +105°C.
• Package and mounting: Radial can package (φ12.5 × 35.5 mm), radial lead mounting with 5.0 mm lead spacing (±0.5 mm) and Pb-free leadwire/sleeve configuration.
• Compliance and availability: RoHS compliant and listed as Mass Production.

Typical Applications

• General-purpose power filtering: Bulk smoothing and decoupling on low-voltage (6.3 V) DC rails where high capacitance and ripple handling are required.
• Power-supply ripple management: Handling AC ripple currents in DC/DC converter outputs and linear regulators to stabilize voltage rails.
• Energy storage for local hold-up: Short-term energy buffering on boards requiring compact, high-capacitance components with long endurance.

Unique Advantages

• High ripple tolerance: Specified ripple currents at both low and high frequencies enable reliable performance under AC-loaded conditions.
• Low impedance at frequency: 29 mΩ impedance reduces voltage drop and improves transient response for decoupling and smoothing tasks.
• Compact radial-can footprint: φ12.5 × 35.5 mm size with 5 mm lead spacing delivers high capacitance in a small package for dense PCB designs.
• Long-term thermal endurance: 6000 hours at 105°C supports demanding thermal environments and extended service life expectations.
• Clear specification set: Measured tanδ and leakage current values provide predictable behavior for circuit design and verification.
• Manufactured at scale: Mass production status supports consistent availability for volume designs.
