UKW1E682MHD

The UKW1E682MHD is a Nichicon UKW-series aluminum electrolytic capacitor in a radial-lead can, rated 6800 µF at 25 V. It is designed for audio and AV equipment applications that require high bulk capacitance in a compact package.

With a rated ripple current of 2.59 A at 120 Hz and 2.978 A at high frequency, a −40 °C to 85 °C operating range, and a 2000-hour endurance at 85 °C, this capacitor delivers reliable energy storage and smoothing for power circuits in audio systems while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 6800 µF nominal capacitance at a 25 V rated voltage, suitable for reservoir and smoothing applications in audio power supplies.
• Ripple Current Performance — Low-frequency ripple current of 2.59 A (120 Hz) and high-frequency ripple current of 2.978 A (10 kHz), supporting continuous AC stress and reducing voltage ripple under load.
• Loss Characteristics — Measured tangent of loss angle (tan δ) of 0.26 at 20 °C / 120 Hz, providing a defined dissipation characteristic for thermal and stability planning.
• Reliability & Endurance — Qualified for 2000 hours at 85 °C; after this endurance test the part meets specified limits for capacitance change, tan δ, and leakage current.
• Temperature Range — Rated for operation from −40 °C to 85 °C to handle a wide range of environmental conditions.
• Form Factor & Mounting — Radial lead, can-style package with dimensions φ18 × 35.5 mm (D × L) and 7.5 mm lead spacing (±0.5 mm), enabling straightforward through-hole mounting.
• Tolerance & Polarization — Capacitance tolerance of −20% to +20% and polarized construction; suitable for DC power circuits where polarity is defined.
• Packaging & Availability — Available in bulk (no terminal forming) or bag packing; status: mass production. RoHS compliant.

Typical Applications

• Audio Power Supplies — Bulk reservoir and smoothing capacitor for amplifier and AV power rails to reduce low-frequency ripple and support transient current demands.
• Preamp and Filter Circuits — Energy storage and decoupling in analog audio stages where large capacitance and stable performance are required.
• AV Equipment — General-purpose smoothing and power conditioning in audio/video devices that require a compact, high-capacitance through-hole component.

Unique Advantages

• High Bulk Capacitance: 6800 µF provides substantial energy storage for smoothing and transient support in audio power systems, reducing output ripple.
• Strong Ripple Handling: Specified ripple current values at both low and high frequency help minimize heating and extend operational life under AC stress.
• Endurance at Elevated Temperature: 2000 hours at 85 °C gives designers a clear durability metric for thermal-stressed applications.
• Compact Radial Can: φ18 × 35.5 mm package delivers large capacitance in a small footprint for through-hole PCBs.
• Supply Chain Ready: Mass-production status and standard packing options support volume manufacturing and simple procurement.
• Regulatory Compliance: RoHS compliance ensures suitability for product lines requiring restricted-substance adherence.
