UKL1V680KPD

The UKL1V680KPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UKL low-leakage series. It provides 68 µF capacitance at a 35 V rating with low leakage characteristics and is supplied in a compact φ8 × 11.5 mm can suitable for through-hole assemblies.

This part targets audio and other circuits that require polarized bulk capacitance with modest ripple handling and long-term endurance up to 2000 hours at 85 °C. Note: this product is End Of Life and is scheduled for discontinuation; it is not recommended for new designs.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a rated voltage of 35 V and tolerance of −10% to +10% (K).
• Low Leakage Performance — Part of Nichicon’s UKL low-leakage series; leakage current specified at 4.76 µA (measurement conditions per datasheet).
• Loss Angle / Stability — tanδ of 0.08 measured at 20 °C and 120 Hz, supporting stable performance in AC applications.
• Ripple Current Capability — 230 mA at 120 Hz (low frequency) and 460 mA at 10 kHz (high frequency), enabling use where moderate ripple filtering is required.
• Endurance & Temperature Range — Rated for 2000 hours at 85 °C with an operating temperature range of −40 °C to +85 °C.
• Package & Mounting — Radial-lead, polarized aluminum can; physical size φ8 × 11.5 mm with 3.5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• Audio circuits — Used for power supply smoothing, decoupling, and signal-coupling in consumer and pro audio equipment where low leakage and compact through-hole capacitors are required.

Unique Advantages

• Low self-discharge (low leakage) — Minimizes leakage-related drift in standby and bias circuits, preserving stored charge and reducing maintenance in low-current sections.
• Compact through-hole form factor — φ8 × 11.5 mm can and 3.5 mm lead spacing save PCB area while keeping robust mechanical mounting for hand-assembled or wave-soldered boards.
• Balanced ripple performance — Specified ripple currents at both 120 Hz and 10 kHz support applications that see a range of operating frequencies.
• Temperature and endurance-rated — 2000 hours at 85 °C rating and −40 °C to +85 °C operating range provide predictable life performance in typical electronics environments.
• RoHS compliance — Meets regulatory requirements for lead-free assembly processes.

Why Choose UKL1V680KPD?

UKL1V680KPD combines low leakage behaviour, controlled loss angle (tanδ), and defined ripple capability in a small radial-lead aluminum can, making it suitable for audio and other PCB applications that require compact polarized bulk capacitance. Its 2000‑hour endurance at 85 °C and RoHS compliance provide predictable lifetime behavior and regulatory alignment for existing designs.

Because this part is part of Nichicon’s UKL low-leakage series, it is a practical option when replacing or maintaining legacy through-hole boards that rely on small, low-leakage electrolytics; however, note that the product is End Of Life and is not recommended for new designs.
