UKL2A680KPD

The UKL2A680KPD is a radial-lead aluminum electrolytic capacitor designed for audio applications. It provides a 68 µF capacitance at a 100 V rated voltage in a compact φ10 × 20 mm radial can, offering low leakage and controlled loss characteristics for reliable performance in audio circuitry.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 100 V rated voltage and ±10% tolerance, specified at 120 Hz, 20°C.
• Low Leakage Current — Rated leakage current of 13.6 µA, supporting stable bias conditions in DC-coupled and power-rail circuits.
• Low Loss (tan δ) — Specified tanδ of 0.08, indicating reduced dielectric losses for audio-related applications.
• Ripple Current Capability — 290 mA at 120 Hz (low frequency) and 580 mA at 10 kHz (high frequency), suitable for filtering and decoupling in power paths where ripple is present.
• Reliability & Lifetime — Rated for 2000 hours life at 85°C with the rated voltage applied, providing known endurance for production and repair scenarios.
• Package & Mounting — Radial lead, can-style package (φ10 × 20 mm) with 5 mm lead spacing for through-hole assembly and straightforward board layout.
• Operating Range & Compliance — Operating temperature range of −40°C to 85°C and RoHS-compliant construction.

Typical Applications

• Audio Power Supply Filtering — Use in amplifier and preamplifier power rails where a 100 V rating and low leakage help maintain stable DC bias and reduce hum.
• Audio Signal Conditioning — Suitable for coupling and decoupling stages in audio equipment that require low-loss behavior (tan δ 0.08) for signal integrity.
• Repair and Replacement — Compact radial can and standard lead spacing make this part suitable for board-level replacements in audio electronics and legacy equipment.

Unique Advantages

• High Working Voltage: 100 V rating enables use in higher-voltage audio power supplies and rail configurations.
• Controlled Leakage: Low leakage current (13.6 µA) supports stable DC operating points in sensitive audio circuits.
• Low Dissipation: tanδ of 0.08 reduces dielectric losses, helping preserve audio fidelity in signal paths.
• Frequency-Responsive Ripple Handling: Specified ripple current values at both 120 Hz and 10 kHz make behavior predictable across low and high ripple environments.
• Compact Through-Hole Form Factor: φ10 × 20 mm radial can with 5 mm lead spacing simplifies layout and mechanical replacement tasks.
• RoHS Compliant: Meets environmental compliance requirements for modern electronics manufacturing.
