UKL1H102MHD

The UKL1H102MHD is a radial‑lead aluminum electrolytic capacitor from the Nichicon UKL series, engineered for low leakage current applications. It provides 1000 µF capacitance at a 50 V rating in a φ16 × 30.5 mm can with 7.5 mm lead spacing.

Designed for audio applications, this capacitor combines a low leakage characteristic and defined ripple current handling with a –40 °C to 85 °C operating range and a 2000 hour endurance at 85 °C, making it suitable for through‑hole assemblies where reliability and stable performance are required.

Key Features

• Capacitance & Tolerance — 1000 µF nominal capacitance with ±20% tolerance (M), enabling bulk energy storage and decoupling where specified capacitance is required.
• Rated Voltage — 50 V DC rating for mid‑voltage power rails in audio systems.
• Low Leakage Current — Specified leakage current of 100 µA, supporting lower standby losses and minimizing bias shift in sensitive circuits.
• Loss Tangent (tan δ) — tan δ = 0.1 measured at 20 °C, 120 Hz, indicating predictable ESR‑related characteristics for filter and coupling applications.
• Ripple Current Capability — Low frequency ripple current of 1.14 A at 120 Hz and high frequency ripple current of 1.311 A at 10 kHz to handle AC content on power rails.
• Endurance & Temperature Range — Rated for 2000 hours at 85 °C and an operating range of –40 °C to 85 °C, providing defined long‑term behavior in ambient and elevated conditions.
• Form Factor & Mounting — Radial lead, polarized can (φ16 × 30.5 mm) with 7.5 mm lead spacing (±0.5 mm), suitable for through‑hole PCB layouts.
• Packaging & Compliance — Available in bulk (no terminal forming) or bag packing; RoHS compliant.

Typical Applications

• Audio systems — Filtering and bulk energy storage on amplifier power rails where low leakage and defined ripple handling improve performance and stability.
• Power supply decoupling (audio electronics) — Stabilizing DC supplies in consumer and pro audio modules requiring 1000 µF at 50 V.
• Through‑hole board designs — Where a radial can capacitor with standardized lead spacing and clear endurance specification is required for assembly and serviceability.

Unique Advantages

• Low leakage characteristic — Minimizes unwanted DC loss and helps preserve bias conditions in audio circuits and sensitive power paths.
• Defined ripple handling across frequencies — Rated ripple currents at 120 Hz and 10 kHz provide predictable filtering performance for both mains‑related and higher‑frequency components.
• Clear endurance specification — 2000 hours at 85 °C gives a measurable reliability target for thermal life planning and maintenance cycles.
• Through‑hole radial form factor — Established mechanical footprint (φ16 × 30.5 mm, 7.5 mm lead spacing) simplifies PCB layout and replacement in field serviceable equipment.
• RoHS compliant — Meets regulatory material requirements for lead‑free assemblies.
