UHE0J681MPD

The UHE0J681MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can designed for general-purpose electronic power applications. It delivers 680 µF at 6.3 V in a compact φ8 × 11.5 mm package with low impedance and extended endurance for sustained operation at elevated temperature.

Engineered for circuits that require bulk capacitance, ripple handling and long service life, this Nichicon UHE-series part is suited for power supply filtering, decoupling and energy storage in industrial and consumer electronics where a compact, polarized electrolytic solution is required.

Key Features

• Capacitance and Voltage: 680 µF rated capacitance at 6.3 V, with a tolerance of −20% to +20% for predictable bulk energy storage.
• Low Impedance: Specified impedance of 520 mΩ contributes to improved ripple attenuation and transient response in power circuits.
• High Reliability / Long Life: Endurance rated for 6000 hours at 105°C (application of DC bias plus rated ripple current), supporting sustained elevated-temperature operation.
• Ripple Current Capability: Low-frequency ripple current 480 mA (120 Hz) and high-frequency ripple current 640 mA (10 kHz), enabling support for both mains-frequency and switching regulator environments.
• Leakage and Loss: Leakage current specified at 42.84 µA and tan δ up to 0.22 (20°C, 120 Hz), providing quantifiable dissipation and leakage behavior for design margin calculations.
• Wide Operating Temperature: Rated for −40°C to +105°C, suitable for a broad range of environmental conditions.
• Compact Radial Package: φ8 × 11.5 mm can with radial lead mounting, 3.5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• RoHS Compliant: Conforms to RoHS requirements as indicated in the product data.

Typical Applications

• Power Supply Filtering: Bulk decoupling and smoothing on low-voltage power rails where 680 µF and low impedance improve ripple suppression and hold-up.
• Switch-Mode Power Supplies: Input/output filtering for DC–DC converters and switching regulators, leveraging the specified high-frequency ripple current rating.
• Industrial Control Electronics: Decoupling and energy storage in control modules operating across −40°C to +105°C, benefiting from the part’s extended endurance.
• Backup and Hold-Up Circuits: Local energy reservoir for short-term power stability in compact assemblies thanks to the high capacitance-to-volume ratio.

Unique Advantages

• Measurable Dissipation Characteristics: Specified tan δ (0.22 at 6.3 V, 20°C, 120 Hz) and impedance (520 mΩ) let engineers quantify ESR-related losses for thermal and stability analysis.
• Validated Long-Term Performance: 6000-hour endurance at 105°C provides a defined lifetime metric for product qualification and reliability planning.
• Frequency-Resilient Ripple Handling: Separate ripple current ratings for low and high frequency (480 mA at 120 Hz, 640 mA at 10 kHz) support both mains-frequency smoothing and high-frequency switching environments.
• Space-Efficient Form Factor: φ8 × 11.5 mm radial can and 3.5 mm lead spacing minimize board area while retaining substantial capacitance for compact designs.
• Procurement-Ready Packaging: Available in bulk (no terminal forming) or bag packing to match different assembly workflows and handling preferences.
• Regulatory Compliance: RoHS compliance supports deployment in regions requiring restricted-substance conformity.
