UCY2G680MHD9

The UCY2G680MHD9 is a radial-lead aluminum electrolytic capacitor designed for high-voltage, high-ripple current applications. It offers 68 µF capacitance at a 400 V rating in a compact φ16 × 25L can with 7.5 mm lead spacing.

Engineered for demanding environments, this polarized, AEC‑Q200 qualified device targets power-supply, ballast and automotive power electronics where long life and stable ripple performance at elevated temperature are required.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 400 V rated voltage and tolerance of −20% to +20%.
• High ripple current capability — Supports 640 mA at 120 Hz (low frequency) and 1.28 A at 100 kHz (high frequency), enabling robust AC load handling in power circuits.
• Long endurance at elevated temperature — Rated for 12,000 hours at 105°C under D.C. bias plus rated ripple current, supporting extended service life in hot operating conditions.
• Low-frequency loss — Tangent of loss angle (tan δ) 0.24 measured at 20°C, 120 Hz, for predictable dissipation characteristics.
• Leakage current — Specified leakage current of 1,188 µA (measured after 1 minute at rated voltage, 20°C), suitable for high-voltage designs that require known DC leakage characteristics.
• Environment & qualification — RoHS compliant and AEC‑Q200 qualified for use in regulated electronic platforms and automotive applications.
• Mechanical & mounting — Radial lead, polarized can (φ16 × 25L) with 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for production handling.
• Temperature range — Operational from −40°C to +105°C to cover a wide set of environmental conditions.
• Frequency ripple current scaling — Frequency coefficients for rated ripple: 50 Hz = 0.80, 120 Hz = 1.00, 1 kHz = 1.60, 10 kHz = 1.80, 100 kHz+ = 2.00.

Typical Applications

• Power supplies — Bulk and smoothing capacitor for high-voltage DC rails and industrial power-supply stages where high ripple current capability is required.
• Ballasts and lighting drives — Energy-storage and filtering in ballast circuits where long life at elevated temperature is needed.
• Automotive power electronics — Filtering and energy buffering in automotive modules and electronic control units, leveraging AEC‑Q200 qualification and high-temperature endurance.

Unique Advantages

• High ripple handling across frequency — Clear low- and high-frequency ripple specifications (640 mA at 120 Hz, 1.28 A at 100 kHz) let designers size thermal and ripple budgets precisely.
• Proven high-temperature durability — 12,000-hour endurance at 105°C under rated conditions supports maintenance-reduced designs and longer field lifetimes.
• Compact, serviceable form factor — φ16 × 25L radial can with standard 7.5 mm lead spacing fits compact power boards while remaining easy to solder and service.
• Quantified leakage and dissipation — Specified leakage current (1,188 µA) and tan δ (0.24) provide predictable DC and loss behavior for reliable thermal and energy-loss calculations.
• Industry qualification and compliance — AEC‑Q200 qualification and RoHS compliance support adoption in regulated and automotive-related designs.
• Production-ready supply — Part is in mass production and offered in bulk or bag packing to suit production workflows.
