UHW1J681MHD6

The UHW1J681MHD6 is a Nichicon UHW-series radial lead aluminum electrolytic capacitor rated at 680 µF and 63 V. It combines a compact φ16 × 20 mm can with high ripple current capability and low impedance for general-purpose power applications.

Designed for engineers requiring reliable bulk capacitance in a small radial package, this component targets general-purpose electronic designs that need high ripple handling, long life at elevated temperatures, and RoHS compliance.

Key Features

• Capacitance & Voltage: 680 µF capacitance with a 63 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Current: Low-frequency ripple current of 1.428 A (120 Hz) and high-frequency ripple current of 2.38 A (10 kHz), supporting demanding power-filtering applications.
• Low Impedance & Loss: Measured impedance of 150 mΩ and tan δ of 0.09 (20°C, 120 Hz), providing effective performance at higher frequencies.
• Reliability & Endurance: Rated lifetime of 12,000 hours at 105°C, with specified limits for capacitance change, tan δ, and leakage after endurance testing.
• Temperature Range: Operating range from −40°C to +105°C for stability across typical environmental conditions.
• Package & Mounting: Radial lead (polarized) can, size φ16 × 20 mm, lead spacing 7.5 mm ±0.5 mm; available in bulk or bag packing for production flexibility.
• Leakage Current Specified: Leakage current provided as 428.4 µA (measured condition after rated voltage applied), enabling predictable bias conditions in designs.
• Compliance: RoHS compliant, aligning with common environmental requirements.

Typical Applications

• Power Supplies — Bulk smoothing and filtering where high ripple current capacity and low impedance are required for stable DC rails.
• Power Conversion — Support for converters and inverters that require compact capacitors with robust high-frequency ripple handling.
• Industrial Control — Use in general-purpose control electronics that operate across −40°C to +105°C and demand long-term endurance.
• General Electronics — Suitable for a wide range of general-purpose circuits needing polarized bulk capacitance in a radial form factor.

Unique Advantages

• High ripple handling: Specified ripple currents at 120 Hz and 10 kHz (1.428 A and 2.38 A) reduce thermal stress in high-activity power circuits.
• Compact footprint: φ16 × 20 mm size delivers 680 µF capacitance in a small radial can, helping conserve board area.
• Long endurance at elevated temperature: 12,000-hour lifetime at 105°C provides predictable long-term performance in hot operating environments.
• Predictable AC behavior: Low impedance (150 mΩ) and tan δ (0.09 at 120 Hz) offer stable frequency response for decoupling and filtering tasks.
• Design-ready packaging: Supplied in bulk or bag packing with standard lead spacing (7.5 mm ±0.5 mm) to streamline assembly and procurement.
• Regulatory alignment: RoHS compliance ensures conformity with environmental material requirements.
