UKT1A682MHD

The UKT1A682MHD is a radial-lead aluminum electrolytic capacitor in the Nichicon UKT series, specified for audio and related electronic equipment. This polarized, high-capacitance component delivers 6.8 mF at 10 V with a compact φ12.5 × 40 mm can and 5 mm lead spacing for through-hole mounting.

Designed for elevated operating temperatures and sustained ripple environments, the UKT1A682MHD offers a combination of high ripple-current capability, wide operating temperature range, and endurance suitable for demanding audio filter and power-smoothing roles.

Key Features

• High Capacitance: 6.8 mF (6800 µF) nominal capacitance ideal for bulk energy storage and audio smoothing tasks.
• Rated Voltage & Tolerance: 10 V rated voltage with ±20% capacitance tolerance at 120 Hz, 20°C for predictable performance in design.
• Ripple Current Handling: 1.57 A at 120 Hz (low frequency) and 1.806 A at 10 kHz (high frequency) to support demanding AC ripple conditions.
• Loss & Leakage: Specified tangent of loss angle (tan δ) of 0.32 at 20°C, 120 Hz and leakage current of 2040 µA, enabling designers to account for dissipation and standby current.
• Wide Temperature Range & Endurance: Rated for operation from −55°C to +105°C with 1000 hours endurance at 105°C to address long-term thermal stress.
• Radial Through‑Hole Package: φ12.5 × 40 mm can with 5 mm lead spacing; radial can construction and bulk/bag packing for standard assembly workflows.
• Compliance & Qualification: RoHS compliant and AEC‑Q200 rated as indicated in the product specifications.

Typical Applications

• Audio Equipment: Bulk filtering and power supply smoothing in amplifiers, preamplifiers, and audio power stages to stabilize rails and reduce ripple.
• Power Supply Filtering: Input/output smoothing in DC power supplies and regulator circuits where high capacitance at low voltage is required.
• General Industrial Electronics: Energy storage and decoupling in control and signal-processing modules operating across a wide temperature range.

Unique Advantages

• Large Stored Energy in a Compact Can: 6800 µF in a φ12.5 × 40 mm package provides significant capacitance density for through-hole designs.
• Designed for Ripple-Stressed Circuits: High specified ripple currents at both low and high frequencies reduce the need for parallel components to share ripple load.
• Thermal Endurance: 1000 hours at 105°C gives designers a clear endurance metric for high-temperature applications and lifetime planning.
• Engineer-Friendly Specifications: Clear published values for tan δ, leakage, tolerance, and ripple currents make it straightforward to model performance in power and audio circuits.
• Compliance and Reliability Indications: RoHS compliance and AEC‑Q200 listing support regulated designs and reliability-focused applications.
• Standard Packaging for Production: Bulk and bag packing options simplify procurement for prototype and production quantities.
