UHE1H182MHD6

The UHE1H182MHD6 is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHE series. It provides 1800 µF capacitance at a 50 V rating in a compact φ18 × 30.5 mm can with 7.5 mm lead spacing.

Designed for general-purpose usage, the device combines high capacitance, low impedance (57 mΩ), and long-life endurance (10,000 hours at 105 °C) to support designs that require sustained ripple handling and stability across –40 °C to 105 °C.

Key Features

• Electrical Performance  1800 µF capacitance with ±20% tolerance and rated voltage of 50 V; low impedance specified at 57 mΩ for improved performance in power circuits.
• Ripple and Loss Characteristics  Rated ripple current of 2.908 A at 120 Hz and 3.635 A at 10 kHz; tangent of loss angle (tan δ) specified at 0.10 for 50 V (120 Hz, 20 °C).
• Reliability & Lifetime  Endurance specified up to 10,000 hours at 105 °C (for 16–100 V rated values), supporting long-term operation under elevated temperature and DC bias.
• Mechanical & Package  Radial lead (can) package, dimensions φ18 × 30.5 mm (L: 3.05 × D: 1.8 cm), lead spacing 7.5 mm, supplied Bulk (No Terminal Forming) / Bag Packing for mass production.
• Operating Temperature Range  Specified for −40 °C to 105 °C, enabling use across a wide ambient temperature span.
• Leakage Current  Leakage current specified as 900 µA in the product data, with datasheet guidance that leakage after 2 minutes at 20 °C is not more than 0.01CV (µA).
• Environmental Compliance  RoHS compliant.

Typical Applications

• General Purpose  Suited to general-purpose circuits that require 1800 µF bulk capacitance and a 50 V rating across −40 °C to 105 °C.
• High-Ripple Circuits  Appropriate where elevated ripple current capability is needed, with specified ripple currents at 120 Hz and 10 kHz.
• Through-Hole Assemblies  Designed for radial-lead, can-type mounting with 7.5 mm lead spacing and bulk/bag packing for volume assembly processes.

Unique Advantages

• Long operational life: 10,000 hours endurance at 105 °C (for 16–100 V ratings) helps maintain capacitance and performance over extended deployment.
• Low impedance: 57 mΩ impedance reduces AC voltage drop and improves transient performance where low ESR is beneficial.
• Robust ripple handling: Rated ripple currents of 2.908 A (120 Hz) and 3.635 A (10 kHz) provide quantifiable capability for smoothing and filtering under AC ripple stress.
• Compact radial can package: φ18 × 30.5 mm form factor and 7.5 mm lead spacing offer a balance of capacitance density and through-hole assembly compatibility.
• Wide temperature range: −40 °C to 105 °C operating range supports designs that must tolerate varying ambient conditions.
• RoHS compliant supply: Meets RoHS requirements for environmentally regulated assemblies.
