UKL1E680MPD

The UKL1E680MPD is a Nichicon UKL-series aluminum electrolytic capacitor designed for low leakage current in a compact radial-lead can. It provides 68 µF capacitance at a 25 V rating with a polar design and is intended for audio applications where low leakage and stable performance matter.

Note: this product is marked End of Life and the UKL series is listed as scheduled for discontinuation; it is not recommended for new designs.

Key Features

• Capacitance & Voltage — 68 µF rated capacitance at 25 V, with ±20% tolerance, suitable where moderate energy storage and smoothing are required.
• Low Leakage Current — Specified leakage current of 3.4 µA and the UKL series’ low-leakage construction reduce standby drain and drift over time.
• Low Dissipation Factor — tan δ of 0.08 (at 25 V / 120 Hz, 20°C) for reduced loss in AC applications relevant to audio circuits.
• Endurance — Rated life of 2000 hours at 85°C, with defined post-test limits for capacitance, tan δ, and leakage current.
• Ripple Handling — Rated ripple current of 230 mA at 120 Hz and 460 mA at 10 kHz (values at 85°C), supporting typical low-frequency to high-frequency ripple conditions.
• Mechanical & Packaging — Radial lead, polar can package with φ8 × 11.5 mm size, 3.5 mm lead spacing; supplied in bulk/bag packing for through-hole assembly.
• Operating Range & Compliance — Operating temperature −40°C to +85°C and RoHS compliant.

Typical Applications

• Audio power filtering — Use for smoothing and decoupling in audio power rails where low leakage and 25 V rating match system requirements.
• Audio amplifier circuits — Suitable where moderate capacitance and low tan δ help maintain signal integrity and reduce loss in amplifier stages.
• Consumer audio equipment — Compact radial package fits through-hole PCB designs for speakers, mixers, and other audio devices requiring reliable electrolytic filtering.

Unique Advantages

• Low standby drain: 3.4 µA leakage current reduces parasitic current draw in idle or low-power audio systems.
• Measured loss performance: tan δ of 0.08 minimizes loss in AC and audio-frequency conditions, supporting clearer signal paths.
• Defined high-temperature endurance: 2000 hours at 85°C gives a clear reliability expectation for designs within the specified operating range.
• Compact through-hole footprint: φ8 × 11.5 mm can with 3.5 mm lead spacing simplifies placement in space-constrained PCB layouts.
• Frequency-aware ripple ratings: Ripple current specifications at 120 Hz and 10 kHz provide designers with quantifiable thermal and AC handling data.
• Regulatory readiness: RoHS compliance supports environmental requirements for many commercial products.

Why Choose UKL1E680MPD?

The UKL1E680MPD combines a compact radial can with low leakage, low dissipation factor, and clearly specified ripple and endurance performance—making it a straightforward choice for established audio designs that require predictable electrolytic behavior. Its polar radial configuration and bulk/bag packaging suit through-hole assembly workflows.

Because the part is listed as End of Life and the UKL series is scheduled for discontinuation, this capacitor is best suited for maintenance, repair, or existing-production use where form, fit, and known performance are priorities rather than new product development.
