UHE2A680MPD

The UHE2A680MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UHE high-reliability series. It delivers 68 µF capacitance at a 100 V rating in a compact φ10 × 16 mm can, optimized for general-purpose power filtering and decoupling in industrial and electronic equipment.

Designed for long life and low impedance, this part supports high-frequency ripple currents and continuous operation across a wide temperature range (‑40 °C to 105 °C), providing stable performance for designs that require extended endurance and reliable smoothing capability.

Key Features

• Capacitance & Tolerance — 68 µF nominal capacitance with a tolerance of ±20% (‑20% to +20%) measured at 120 Hz, 20 °C.
• Rated Voltage & Polarization — 100 V rated voltage; polarized aluminum electrolytic construction for DC applications.
• Low Loss / Low Impedance — Tangent of loss angle (tan δ) 0.08 (at 100 V, 120 Hz, 20 °C) and specified impedance of 1.5 Ω for effective AC ripple handling and reduced heat generation.
• Ripple Current Capability — Low-frequency ripple current 280 mA (120 Hz) and high-frequency ripple current 400 mA (10 kHz), supporting both mains-frequency smoothing and higher-frequency decoupling.
• Leakage Current — Specified leakage current of 68 µA after rated voltage application, aiding predictable bias behavior in DC circuits.
• Long Endurance — Rated life of 7000 hours at 105 °C, aligning with the UHE series’ long-life, high-reliability focus.
• Compact Radial Package — φ10 × 16 mm can, radial lead mounting with 5.0 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for assembly flexibility.
• Operating Range & Compliance — Operating temperature range −40 °C to 105 °C; RoHS compliant.

Typical Applications

• Power Supply Smoothing — Use for DC bus filtering and bulk smoothing where 100 V rating and 68 µF capacitance stabilize supply rails and reduce ripple.
• Switching Power Supplies — Suitable for input/output filtering in switch-mode supplies benefiting from the capacitor’s low impedance and specified ripple current at both low and high frequencies.
• Industrial Control Electronics — Fits compact control boards that require long-life capacitors capable of continuous operation up to 105 °C and reliable bias performance.
• Instrumentation & Test Equipment — Provides stable decoupling and energy buffering in measurement and test systems where predictable leakage and tan δ are important.

Unique Advantages

• Measurable Low Loss Performance — tan δ = 0.08 at 100 V, 120 Hz (20 °C) supports efficient AC handling with quantifiable loss characteristics.
• Broad Ripple Capability — Distinct ripple ratings for 120 Hz and 10 kHz (280 mA and 400 mA respectively) let designers size components to specific frequency domains with confidence.
• Proven Long Life — 7000-hour endurance at 105 °C provides predictable lifetime behavior for applications requiring extended continuous operation.
• Compact Footprint — φ10 × 16 mm radial can and 5 mm lead spacing enable use in space-constrained boards while keeping through-hole mounting simplicity.
• Controlled Leakage — Specified leakage current (68 µA) simplifies bias calculations and power budgeting in precision circuits.
• RoHS Compliant — Meets environmental compliance requirements for regulated markets.
