UHW1K152MHD

The UHW1K152MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series, supplied in a radial lead can. It delivers 1500 µF capacitance at an 80 V rating with a compact φ18 × 35.5 mm case and 7.5 mm lead spacing.

Designed for general-purpose electronic applications, this component combines high ripple-current capability, low impedance at higher frequencies, and long-term endurance (12,000 hours at 105°C) to support demanding power and filtering functions.

Key Features

• Capacitance & Voltage: 1.5 mF (1500 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Current: Low-frequency ripple current of 2.106 A at 120 Hz and high-frequency ripple current of 3.51 A at 10 kHz, enabling effective smoothing under dynamic load conditions.
• Low Impedance: Impedance of 81 mΩ supports improved performance across frequency, consistent with the UHW series’ lower impedance at high frequency.
• Long Endurance: Rated life of 12,000 hours at 105°C when subjected to DC bias plus rated ripple current, with specified limits on capacitance change, tan δ, and leakage after endurance testing.
• Loss Characteristics: Tangent of loss angle (tan δ) of 0.09 measured at 20°C, 120 Hz and 80 V.
• Leakage Current: Specified leakage current of 1200 µA (measured after standard voltage application conditions).
• Temperature Range: Operating range from −40°C to +105°C for broad environmental compatibility.
• Package & Mounting: Radial lead can package (φ18 × 35.5 mm) with 7.5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Regulatory: RoHS compliant.
• Polarization: Polarized aluminum electrolytic construction for DC applications.

Typical Applications

• General-purpose power filtering — Bulk energy storage and smoothing in electronic equipment where an 80 V rating and 1500 µF capacitance are required.
• High-ripple current circuits — Use in circuits that require sustained ripple current handling up to 3.51 A at 10 kHz and 2.106 A at 120 Hz.
• Heat-tolerant designs — Suitable for equipment operating across −40°C to +105°C with a long endurance life of 12,000 hours at 105°C.

Unique Advantages

• Compact, high-capacitance package: 1500 µF in a φ18 × 35.5 mm can provides significant capacitance while minimizing board area.
• High ripple capability: Rated ripple currents (2.106 A at 120 Hz, 3.51 A at 10 kHz) reduce thermal stress and improve reliability in ripple-heavy environments.
• Low high-frequency impedance: 81 mΩ impedance and UHW-series design characteristics help maintain performance at higher frequencies.
• Extended high-temperature life: 12,000 hours endurance at 105°C supports long-term stability in elevated-temperature applications.
• Clear mechanical fitment: Radial lead form with 7.5 mm lead spacing and defined lead tolerance simplifies through-hole layout and assembly.
• Regulatory compliance: RoHS status supports deployments where restricted-substance compliance is required.
