UHE1E182MHD6

The UHE1E182MHD6 is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic designs. It delivers 1.8 mF capacitance at a 25 V rating with low impedance and long-life endurance, making it suitable for applications that require bulk energy storage, decoupling, and smoothing in compact assemblies.

Key value comes from a combination of high ripple-current capability, a –40 °C to 105 °C operating range, and a 10,000-hour rated life at 105 °C, providing predictable performance and durability in demanding environments.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Impedance & Loss — Low impedance construction with an impedance of 78 mΩ and a specified tanδ (DF) of 0.14 measured at 20 °C, 120 Hz.
• High Ripple Current Handling — Rated low-frequency ripple current of 2.024 A at 120 Hz and high-frequency ripple current of 2.53 A at 10 kHz for effective AC stress handling.
• Leakage Current — Specified leakage current of 450 µA after application of rated voltage at 20 °C.
• Long Life & Reliability — Endurance rated for 10,000 hours at 105 °C, designed for prolonged operation under rated bias and ripple conditions.
• Compact Radial Package — φ16 × 20 mm can size with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for straightforward through-hole assembly; available in bulk or bag packing (no terminal forming).
• Wide Temperature Range & Compliance — Operating range from –40 °C to 105 °C and RoHS compliant.

Typical Applications

• General-purpose power supply smoothing — Bulk energy storage and output filtering where 1.8 mF at 25 V is required to stabilize supply rails.
• Decoupling for analog and digital circuits — Local decoupling to support transient loads and reduce ripple with proven low impedance and rated ripple currents.
• Embedded and industrial electronics — Use in compact through-hole designs that require long-life capacitors able to operate from –40 °C to 105 °C for continuous duty.

Unique Advantages

• Reliable long-term performance: Rated for 10,000 hours at 105 °C to provide predictable aging characteristics under elevated temperature and ripple stress.
• High ripple capability: Dual ripple-current ratings at 120 Hz and 10 kHz support both low- and high-frequency AC stress in power systems and converters.
• Low-impedance behavior: 78 mΩ impedance reduces voltage drop under load and improves transient response when used for bulk and bypass applications.
• Compact radial form factor: φ16 × 20 mm can with 7.5 mm lead spacing offers space-efficient through-hole mounting for hand or automated insertion.
• Measured dielectric loss: Specified tanδ of 0.14 at 20 °C, 120 Hz, enabling designers to account for dielectric dissipation in thermal and life calculations.
• Regulatory compliance: RoHS compliant for use in designs targeting environmental directive requirements.
