UHE1H182MHD

The UHE1H182MHD is an aluminum electrolytic capacitor from Nichicon's UHE series, designed for miniature, low-impedance, long-life performance in general-purpose electronic applications. It provides 1800 µF capacitance at 50 V in a compact φ16 × 40 mm radial-can package with 7.5 mm lead spacing.

Key value comes from a combination of high ripple-current capability, long endurance (10,000 hours at 105°C for 16–100 V ratings), and a wide operating temperature range of −40°C to 105°C—making it suitable where reliable bulk capacitance and ripple handling are required.

Key Features

• Capacitance & Rated Voltage — 1.8 mF (1800 µF) rated at 50 V for bulk energy storage and smoothing in DC circuits.
• Low Impedance — Typical impedance 48 mΩ supports lower ESR requirements for improved ripple performance.
• High Ripple Current Capability — Low-frequency ripple current 2.968 A (120 Hz) and high-frequency ripple current 3.71 A (100 kHz) for demanding ripple environments.
• Long Endurance — Designed for 10,000 hours at 105°C (for 16–100 V class), supporting extended operational life under elevated temperature and bias.
• Wide Temperature Range — Rated from −40°C to +105°C for deployment across varied thermal environments.
• Compact Radial Package — φ16 × 40 mm can with radial leads and 7.5 mm lead spacing (±0.5 mm) for conventional through-hole PCB mounting; available bulk or bag packing.
• Leakage & Tolerance — Leakage current specified at 900 µA and capacitance tolerance of −20% to +20% for predictable performance.
• RoHS Compliant — Conforms to RoHS directive requirements for restricted substances.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and low impedance for smoothing and filtering in power rails where 50 V rating and 1800 µF are required.
• Power-supply decoupling — Handles sustained ripple currents (up to 3.71 A at high frequency) for decoupling in DC/DC converters and regulator outputs.
• Embedded and industrial electronics — Long 10,000-hour endurance at 105°C and wide −40°C to 105°C temperature range support reliable operation in demanding environments.

Unique Advantages

• High ripple-current tolerance: Enables stable operation under significant AC loading, reducing thermal stress on the capacitor and surrounding components.
• Low ESR (48 mΩ): Improves overall supply impedance, helping to minimize voltage ripple and heat generation in high-current circuits.
• Extended high-temperature life: 10,000-hour endurance at 105°C provides predictable lifetime for designs that operate at elevated temperatures.
• Compact radial form factor: φ16 × 40 mm can with standard 7.5 mm lead spacing eases replacement and integration into through-hole assemblies.
• Clear specification set: Explicit ratings for capacitance, tolerance, leakage current, and frequency-dependent ripple make selection and thermal/ripple budgeting straightforward.
• RoHS compliant: Meets restricted-substance requirements for environmentally regulated product designs.

Why Choose UHE1H182MHD?

The UHE1H182MHD combines Nichicon's UHE-series focus on miniature, low-impedance construction with a 50 V, 1800 µF rating to deliver reliable bulk capacitance in a compact radial-can package.
