UHE1E182MHD

The UHE1E182MHD is a radial-lead aluminum electrolytic capacitor offering 1.8 mF (1800 µF) capacitance at a 25 V rating in a compact φ12.5 × 30.5 mm can. It is part of Nichicon’s UHE series, designed for miniature, low-impedance, long-life applications.

With a wide operating temperature range of −40 °C to +105 °C, long endurance (10,000 hours at 105 °C for rated voltages 16 V–100 V), and robust ripple-current capability across frequency, this capacitor is targeted at general-purpose power electronics requiring compact size, reliable smoothing, and effective decoupling.

Key Features

• Capacitance and Voltage — 1.8 mF (1800 µF) rated at 25 V, providing bulk energy storage in a miniature radial-lead package.
• Low Impedance — Rated impedance of 78 mΩ supports improved transient response and lower voltage drop under load.
• High Ripple Current Capability — Low-frequency ripple current of 2.12 A (120 Hz) and high-frequency ripple current of 2.65 A (10 kHz), supporting demanding power filtering tasks across frequencies.
• Long Endurance — Specified life of 10,000 hours at 105 °C (for 16–100 V class), delivering extended service life in elevated-temperature environments.
• Loss and Leakage Characteristics — tan δ (DF) of 0.14 measured at 20 °C, 120 Hz, and leakage current specified at 450 µA for predictable loss and standby behavior.
• Compact Radial Package — φ12.5 × 30.5 mm can with 5 mm lead spacing (±0.5 mm) and radial-lead mounting for through-hole or hybrid assembly needs; available in bulk or bag packing.
• Wide Temperature Range and RoHS Compliance — Operating from −40 °C to +105 °C and compliant with RoHS requirements.

Typical Applications

• Power Supply Smoothing — Bulk capacitance and low impedance help smooth DC outputs and reduce ripple in regulated supplies.
• Decoupling and Bulk Energy Storage — Compact 1800 µF capacity supports transient loads and energy buffering in embedded and industrial electronics.
• DC Link and Filter Circuits — High ripple-current capability at both low and high frequencies makes it suitable for filter stages and DC-link applications in power modules.
• General-Purpose Industrial Electronics — Robust temperature and endurance ratings support long-term operation in control, instrumentation, and power-management circuits.

Unique Advantages

• High Capacitance in a Small Footprint: 1800 µF in a φ12.5 × 30.5 mm can minimizes board area while providing substantial energy storage.
• Improved Circuit Performance: Low impedance (78 mΩ) and measured tan δ (0.14 at 20 °C, 120 Hz) contribute to better transient response and lower losses.
• Frequency-Responsive Ripple Handling: Rated ripple currents of 2.12 A at 120 Hz and 2.65 A at 10 kHz support both mains-frequency and high-frequency filtering needs.
• Designed for Long Life at Elevated Temperatures: 10,000-hour endurance at 105 °C (16–100 V class) supports extended maintenance intervals and reliable field operation.
• Through-Hole Versatility: Radial-lead package and standard 5 mm lead spacing simplify mounting options for mixed-technology assemblies.
• Regulatory Compliance: RoHS-compliant construction meets environmental restrictions for many global designs.
