UKA0J682MHD

The UKA0J682MHD is a radial-lead aluminum electrolytic capacitor engineered for high-grade audio equipment and other demanding electronic designs. It delivers 6.8 mF capacitance at a 6.3 V rating in a compact φ12.5 × 35.5 mm can with 5 mm lead spacing.

Designed for wide temperature operation and extended endurance, the UKA0J682MHD combines high capacitance, defined ripple-current capability, and AEC-Q200 rating to address reliability and performance needs in professional audio and related applications.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) rated at 6.3 V with ±20% tolerance suitable for bulk filtering and energy storage in low-voltage circuits.
• Package & Mounting — Radial lead, can-style package (φ12.5 × 35.5 mm) with 5 mm lead spacing for through-hole assembly and straightforward board placement.
• Temperature & Endurance — Operates from −55°C to +105°C and specified for 2000 hours at 105°C, providing predictable aging and lifetime performance.
• Ripple Current Capability — Rated ripple current of 1360 mA at 120 Hz and 1564 mA at 10 kHz supports filtering under AC ripple conditions.
• Dissipation Factor (tan δ) — Specified tan δ ≈ 0.4 at 20°C, 120 Hz, representing the capacitor’s dissipation characteristics for AC performance considerations.
• Leakage Current — Leakage current specified as 1285.2 µA, useful for design budgeting in bias and standby conditions.
• Manufacturing & Packaging — Available in bulk/bag packaging and listed as mass production for volume deployment.

Typical Applications

• Audio Equipment — Bulk filtering and power supply decoupling in amplifiers, preamplifiers, and other high-grade audio gear where reliable low-voltage energy storage is required.
• Power Supply Filtering — Smoothing and ripple attenuation in low-voltage DC rails that demand high capacitance and defined ripple-current handling.
• Embedded Systems — Energy reservoir and decoupling in compact through-hole designs operating across wide temperature ranges.

Unique Advantages

• High capacitance in a compact can: 6.8 mF in a φ12.5 × 35.5 mm package reduces board area for bulk energy storage compared with multiple smaller parts.
• Wide operating range and proven endurance: −55°C to +105°C rating with 2000 hours at 105°C supports long-term operation in thermally demanding environments.
• Defined ripple performance: Clear ripple current ratings at 120 Hz and 10 kHz help designers size the capacitor for AC stress and thermal management.
• AEC-Q200 reliability: AEC-Q200 listing provides an added qualification layer for applications that require recognized component-level reliability standards.
• Through-hole simplicity: Radial lead package with 5 mm spacing eases prototyping and replacement in serviceable assemblies.
• Production-ready supply: Bulk/bag mass-production availability supports volume sourcing and manufacturing continuity.
