UKL1H680MPD

The UKL1H680MPD is a radial‑lead aluminum electrolytic capacitor offering 68 µF capacitance at a 50 V rating in a compact φ10 × 12.5 mm can. It belongs to Nichicon's UKL low‑leakage series and is designed for audio applications where controlled leakage, defined loss angle, and ripple handling are important.

With a −40 °C to 85 °C operating range and a 2000‑hour endurance at 85 °C, the UKL1H680MPD provides predictable performance for designs that require stable capacitance, low leakage, and modest ripple current capability in a small radial package.

Key Features

• Capacitance & Voltage — 68 µF rated capacitance at 50 V for mid‑rail decoupling and energy storage in audio electronics.
• Low Leakage Design — Part of Nichicon's UKL low leakage current series; specified leakage current 6.8 µA (measurement conditions per datasheet).
• Loss Tangent (tan δ) — tanδ of 0.08 measured at 20 °C, 120 Hz, supporting low dissipation in signal‑sensitive circuits.
• Ripple Current Capability — Low frequency ripple current 250 mA at 120 Hz and high frequency ripple current 500 mA at 10 kHz, enabling both power‑rail smoothing and higher‑frequency decoupling.
• Temperature & Endurance — Operating temperature range −40 °C to 85 °C with rated endurance of 2000 hours at 85 °C.
• Form Factor & Mounting — Compact radial can, size φ10 × 12.5 L mm with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• Audio electronics — Suited for power‑supply smoothing and decoupling in audio circuits where low leakage and controlled tanδ help maintain signal quality.
• Amplifier power rails — 68 µF at 50 V provides bulk and transient energy for small to medium amplifier stages.
• General purpose filtering — Compact radial package for board‑level filtering in consumer and professional audio equipment.

Unique Advantages

• Low leakage for signal integrity: Specified low leakage current reduces drain on bias circuits, supporting stable operation in audio paths.
• Measured dissipation (tanδ): tanδ of 0.08 at 120 Hz and 20 °C indicates controlled loss for applications sensitive to heating and distortion.
• Broad ripple handling: Rated ripple specifications at both low and high frequencies (250 mA @120 Hz, 500 mA @10 kHz) cover common audio power and decoupling scenarios.
• Compact radial can: φ10 × 12.5 mm can with 5 mm lead spacing delivers a small footprint for dense PCB layouts while keeping through‑hole mounting simplicity.
• Defined endurance: 2000 hours at 85 °C provides predictable lifetime performance for thermal and reliability planning.
• RoHS compliance: Conforms to RoHS directive requirements for environmentally regulated designs.
