UKL1V101MPD

The UKL1V101MPD is an aluminum electrolytic capacitor from Nichicon's UKL series, offered as a radial-lead, polarized can with a 100 µF capacitance at 35 V. It is part of a low-leakage current family designed for audio applications where controlled leakage, defined ripple handling and compact through‑hole mounting are required.

Key delivered characteristics include low leakage current, defined loss tangent and ripple current ratings, a compact φ10 × 12.5 mm radial package with 5 mm lead spacing, RoHS compliance, and an endurance rating of 2000 hours at 85°C. Note: this part is End Of Life and is scheduled for discontinuation; it is not recommended for new designs.

Key Features

• Capacitance & Rated Voltage — 100 µF nominal capacitance with a 35 V rated voltage and a capacitance tolerance of ±20%.
• Low Leakage Current — Specified leakage current of 7 µA, supporting low standby loss in DC‑biased circuits.
• Loss Tangent (tan δ) — tan δ = 0.08 measured at 20°C, 120 Hz, indicating controlled dielectric loss for signal‑sensitive audio circuits.
• Ripple Current Ratings — Low‑frequency ripple current 300 mA at 120 Hz and high‑frequency ripple current 450 mA at 10 kHz, enabling predictable AC ripple handling across frequencies.
• Endurance & Temperature Range — Lifetime rated 2000 hours at 85°C with an operating temperature range of −40°C to 85°C for sustained performance in elevated ambient conditions.
• Package & Mounting — Radial lead, can-style package sized φ10 × 12.5 mm with 5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Polarized Electrolytic — Polarized component; observe correct polarity in circuit installation.
• Regulatory Compliance — RoHS compliant, meeting directive requirements listed for the series.

Typical Applications

• Audio power supply smoothing — 100 µF/35 V rating and low leakage current make this capacitor suitable for stabilizing audio power rails and reducing low‑frequency ripple.
• Audio decoupling and bypass — Controlled tan δ and ripple current capability provide reliable local decoupling in amplifier and preamplifier circuits.
• Signal-chain support in audio modules — Compact φ10 × 12.5 mm radial can fits through‑hole board layouts where low-loss and defined endurance are required.

Unique Advantages

• Low standby leakage — 7 µA leakage current helps minimize DC losses and preserve bias conditions in audio circuits.
• Frequency-aware ripple capability — Specified ripple current values at 120 Hz and 10 kHz allow designers to size capacitors for both low‑frequency smoothing and higher‑frequency decoupling needs.
• Compact radial package — φ10 × 12.5 mm can with 5 mm lead spacing offers a small footprint for through‑hole designs without sacrificing capacitance.
• Thermal endurance — 2000 hours at 85°C provides predictable life expectancy under sustained elevated temperatures.
• RoHS compliance from a known manufacturer — Manufactured by Nichicon and compliant with RoHS requirements for regulated substances.

Why Choose UKL1V101MPD?

UKL1V101MPD is positioned for audio-focused designs that require a compact, low‑leakage aluminum electrolytic capacitor with clearly defined ripple handling and thermal endurance. Its combination of 100 µF / 35 V rating, low tan δ, and radial can format makes it suitable for refurbishment, repair, and maintenance of existing audio hardware where through‑hole mounting and predictable performance are priorities.

Because this part is End Of Life and scheduled for discontinuation, it is particularly relevant for supply continuity in legacy products and for engineers sourcing direct replacements. Nichicon's UKL series specification set gives clear, verifiable parameters for designers who need measurable leakage, ripple and lifetime characteristics.
