UHE1J681MHD

The UHE1J681MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHE series. It is a radial-lead, polarized capacitor offering 680 µF capacitance at a 63 V rating, engineered for general-purpose electronic designs.

Designed for long operational life and low impedance, this component delivers a combination of high ripple-current capability, broad operating temperature range (−40℃ to 105℃), and 10,000‑hour endurance at 105℃ for demanding applications where longevity and stable performance matter.

Key Features

• Electrical Performance — 680 µF capacitance at 63 V with an impedance of 300 mΩ, tanδ of 0.09 (measured at 20℃, 120 Hz), and capacitance tolerance of −20% to +20% for predictable circuit behavior.
• Ripple Current Handling — Low-frequency ripple current of 960 mA (120 Hz) and high-frequency ripple current of 1.28 A (10 kHz), supporting circuits with significant AC stress on DC rails.
• Leakage Current — Specified leakage current of 428.4 µA for stable quiescent behavior after application of rated voltage.
• Long Life and Reliability — Endurance rated to 10,000 hours at 105℃ (for 16–100 V range, φD ≥ 12.5), providing extended operational lifetime in elevated-temperature environments.
• Mechanical/Package — Compact radial can form factor with dimensions φ12.5 × 40 mm and 5 mm lead spacing (±0.5 mm), available in bulk/bag packing for through-hole assembly.
• Wide Temperature Range — Operating from −40℃ to 105℃ to accommodate a broad set of environmental conditions.
• Regulatory Compliance — RoHS‑compliant construction supporting restricted substance requirements.

Typical Applications

• General Purpose Electronic Circuits — Use where a 680 µF, 63 V polarized capacitor is required for energy storage or smoothing in general-purpose designs.
• High‑Temperature Endurance Designs — Suitable for applications requiring continuous operation up to 105℃ with long life (10,000 hours at 105℃ for applicable sizes and voltages).
• Radial‑Lead Through‑Hole Assemblies — Intended for through-hole mounting where a compact φ12.5 × 40 mm can and 5 mm lead spacing are preferred for mechanical compatibility.

Unique Advantages

• Low Impedance for Stable Performance: 300 mΩ impedance and a low tanδ (0.09 at 20℃, 120 Hz) help minimize voltage ripple and heat generation under load.
• High Ripple Current Capacity: Rated ripple currents of 960 mA (120 Hz) and 1.28 A (10 kHz) allow the capacitor to handle AC stress across a wide frequency range.
• Proven Long‑Life Endurance: 10,000‑hour rating at 105℃ reflects suitability for designs needing sustained reliability at elevated temperatures.
• Compact Radial Can Packaging: φ12.5 × 40 mm package with 5 mm lead spacing provides a space-efficient, easy-to-mount solution for through-hole boards and assemblies.
• predictable Leakage Behavior: Specified leakage current of 428.4 µA supports stable bias conditions after voltage application.
• RoHS Compliance: Meets RoHS requirements for restricted substances.
