UHW1K102MHD

The UHW1K102MHD is a radial‑lead, miniature aluminum electrolytic capacitor from Nichicon’s UHW series designed for general‑purpose applications that require high ripple handling and long endurance. This polarized, through‑hole component delivers 1000 µF at 80 V with a compact φ16 × 35.5 mm can and 7.5 mm lead spacing.

Engineered for reliability at elevated temperatures, the device offers a wide operating range (−40 °C to 105 °C) and a rated endurance of 12,000 hours at 105 °C, making it suitable for designs that demand sustained performance under continuous load.

Key Features

• Electrical Performance — 1000 µF nominal capacitance with ±20% tolerance and rated voltage of 80 V; tangent of loss angle (tan δ) of 0.09 (measured at 20 °C, 120 Hz).
• High Ripple Capability — Low‑frequency ripple current of 1.716 A at 120 Hz and high‑frequency ripple current of 2.86 A at 10 kHz to support applications with significant AC stress.
• Low Impedance — Specified impedance of 86 mΩ helps reduce voltage drop and improve transient response in power circuits.
• Long Endurance — Lifetime/endurance specified at 12,000 hours at 105 °C for sustained high‑temperature reliability.
• Thermal Range — Operating temperature range from −40 °C to 105 °C for broad environmental tolerance.
• Mechanical & Packaging — Compact φ16 × 35.5 mm can size, radial lead mounting with 7.5 mm lead spacing (±0.5 mm), supplied in bulk (no terminal forming) or bag packing; polarized can package for through‑hole assembly.
• Leakage Current — Specified leakage current of 800 µA for predictable DC behavior.
• RoHS Compliance — Component is RoHS compliant.

Typical Applications

• General Purpose — Suitable wherever a polarized aluminum electrolytic capacitor is required for through‑hole designs within the specified electrical and thermal parameters.
• Power Supply Filtering — Used for bulk energy storage and smoothing in power circuits that operate up to 80 V and require sustained ripple handling.
• High‑Temperature Environments — Applied in systems requiring continuous operation at elevated temperatures up to 105 °C with extended endurance.

Unique Advantages

• High ripple handling: With 1.716 A at 120 Hz and 2.86 A at 10 kHz ripple ratings, the capacitor supports significant AC loading without compromising performance.
• Extended life at elevated temperature: Rated endurance of 12,000 hours at 105 °C provides predictable long‑term behavior under thermal stress.
• Compact footprint: φ16 × 35.5 mm can and radial lead form factor offer a space‑efficient solution for through‑hole designs.
• Low impedance: 86 mΩ impedance contributes to reduced voltage drop and improved transient response in power circuits.
• Clear mechanical specifications: 7.5 mm lead spacing (±0.5 mm) and available bulk or bag packing simplify assembly planning and procurement.
• Regulatory compliance: RoHS compliant for use in designs requiring restricted substances conformance.
