UHE1E681MHD6

The UHE1E681MHD6 is a Nichicon UHE-series aluminum electrolytic capacitor in a miniature radial-lead can. It delivers 680 µF at 25 V in a compact φ12.5 × 15 mm package and is designed for general-purpose electronic applications that require low impedance and long-term reliability.

Key value points include low impedance, rated ripple-current capability across low and high frequencies, a wide operating temperature range of −40°C to 105°C, and extended endurance up to 10,000 hours at 105°C.

Key Features

• Electrical Performance — 680 µF nominal capacitance at 25 V with a tolerance of −20% to +20%; rated impedance 160 mΩ and tangent of loss angle (tanδ) 0.14 measured at 20°C, 120 Hz.
• Ripple Current Capability — Low-frequency ripple current 1.0875 A at 120 Hz and high-frequency ripple current 1.45 A at 10 kHz, supporting AC ripple handling across common power and signal frequencies.
• Leakage Current — Specified leakage current of 170 µA, measured after standard conditioning at 20°C.
• Reliability & Life — High-reliability UHE series construction with endurance specified to 10,000 hours at 105°C under rated voltage and ripple-current conditions.
• Mechanical & Mounting — Radial lead mounting with 5 mm lead spacing (±0.5 mm tolerance); can dimensions φ12.5 × 15 mm; lead diameter typical for φ12.5 units is 0.6 mm (0.8 mm if L > 25 mm).
• Packaging Options — Available in bulk (no terminal forming) and bag packing for flexible procurement and assembly workflows.
• Environmental Compliance — RoHS compliant as specified in the product data.

Typical Applications

• General-purpose electronic circuits — Supports a wide range of general-purpose designs requiring bulk capacitance and ripple handling at 25 V.
• High-temperature environments — Rated for −40°C to 105°C with 10,000-hour endurance at 105°C for designs that demand long life at elevated temperatures.
• Compact radial assemblies — φ12.5 × 15 mm can and 5 mm lead spacing suit space-constrained through-hole or mixed-technology boards.

Unique Advantages

• Low impedance performance — 160 mΩ impedance and specified tanδ (0.14) reduce voltage ripple and support stable filtering performance.
• Wide ripple-frequency capability — Defined ripple-current ratings at both 120 Hz and 10 kHz enable predictable behavior across low and high-frequency ripple conditions.
• Extended high-temperature endurance — 10,000-hour life at 105°C minimizes replacement frequency in long-life applications.
• Compact radial form factor — Small-diameter can and short length provide high capacitance in a space-efficient radial-lead package.
• Simplified procurement and handling — Bulk and bag packing options accommodate different assembly and inventory practices.
• Regulatory clarity — RoHS compliance supports use in markets requiring restricted-substance conformity.
