UKT1V682MRD

The UKT1V682MRD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKT series, offering high capacitance (6800 µF) at a 35 V rating in a φ20 × 40 mm can. Designed with audio equipment in mind, it combines high energy storage, wide operating temperature range, and specified ripple current performance for demanding power-handling roles.

Key value propositions include high capacitance for bulk energy storage, engineered endurance at elevated temperature (1000 hours at 105°C), and AEC-Q200 qualification listed for the series.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) rated at 35 V to support large energy storage requirements in power supply and audio applications.
• Tolerance & Polarization — ±20% capacitance tolerance and polarized construction suitable for DC applications.
• High ripple-current capability — Specified ripple current of 2.15 A at 120 Hz and 2.4725 A at 10 kHz, with frequency-dependent ripple coefficients defined by the UKT series data.
• Dissipation factor (tan δ) — 0.26 (DF) measured at 20°C, 120 Hz for this part number.
• Leakage current — Rated leakage current reported as 7140 µA in the product specification.
• Wide temperature and endurance — Operating temperature range from −55°C to +105°C and endurance of 1000 hours at 105°C per the UKT series specification.
• Package & mounting — Radial-lead can (φ20 × 40 mm) with 10 mm lead spacing; supplied bulk (no terminal forming) / bag packing.
• Series-level qualifications — UKT series is noted as AEC-Q200 qualified and published for general audio equipment; see series documentation for details.
• Lifecycle status — Product status listed as End Of Life.

Typical Applications

• Audio equipment — Targeted for general audio equipment where high capacitance and wide temperature range are required.
• Power supply bulk storage — Provides large DC energy storage in designs that require substantial smoothing at up to 35 V.
• High-ripple environments — Suitable where elevated ripple currents are present, using the specified 120 Hz and 10 kHz ripple-current ratings to guide design choices.

Unique Advantages

• High energy density — 6800 µF at 35 V supplies substantial charge storage for power smoothing and hold-up in compact can form.
• Defined ripple performance — Explicit ripple current specifications at both low and high frequencies help engineers size capacitors for thermal and lifetime considerations.
• Extended temperature range — −55°C to +105°C operation supports designs that must tolerate wide environmental variation.
• Endurance rating — 1000 hours at 105°C provides a measurable reliability baseline for thermal-stressed applications.
• Radial can format — Standard φ20 × 40 mm radial can with 10 mm lead spacing simplifies PCB layout for through-hole assemblies.
