UHE0J183MHD

The UHE0J183MHD is a Nichicon UHE series miniature, high-reliability aluminum electrolytic capacitor in a radial lead can. It delivers 18 000 µF at 6.3 V with low impedance and rated endurance for long-life applications.

Designed for general-purpose electronics, this radial-lead unit combines high capacitance, robust ripple handling, and a wide operating temperature range (−40 °C to 105 °C) to support bulk energy storage and smoothing where long-term reliability is required.

Key Features

• High Capacitance — 18 000 µF nominal capacitance with tolerance −20% to +20% for large bulk storage in a compact φ18 × 40L package (L: 4 cm × D: 1.8 cm).
• Rated Voltage — 6.3 V rated voltage suitable for low-voltage power rails and filtering duties.
• Low Impedance — Typical impedance 32 mOhm for improved transient response and reduced voltage ripple under load.
• High Ripple Current Capability — Low-frequency ripple current 3.424 A at 120 Hz and high-frequency ripple current 4.28 A at 10 kHz to handle AC components in power circuits.
• Long Endurance — Rated life 8 000 hours at 105 °C (per UHE series specification for φD ≥ 12.5 at 6.3–10 V), supporting long-term reliability in elevated-temperature environments.
• Loss Characteristics — Tan δ 0.56 measured at 20 °C, 120 Hz for this capacitance and voltage combination, defined by the UHE series specification.
• Leakage Current — Specified leakage current 1 134 µA (measured condition provided in product data), with datasheet references for initial leakage limits (0.01CV after 2 minutes at 20 °C).
• Package & Mounting — Radial lead configuration with 7.5 mm lead spacing (±0.5 mm) for through-hole assembly; supplied bulk (no terminal forming) or bag packed for handling flexibility.
• RoHS Compliant — Meets the stated RoHS compliance in the product data.

Typical Applications

• General Purpose Electronics — Provides large bulk capacitance for smoothing and energy storage where a high-capacitance radial lead aluminum electrolytic is required.
• Power Supply Filtering — Handles AC ripple with specified low- and high-frequency ripple current ratings, making it suitable for filtering and decoupling on low-voltage rails.
• High-Temperature Environments — With an operating range of −40 °C to 105 °C and 8 000-hour life at 105 °C, it supports designs exposed to sustained elevated temperatures.

Unique Advantages

• Substantial Bulk Energy Capacity: 18 000 µF provides significant capacitance in a compact φ18 × 40L can, reducing the need for multiple smaller parts.
• Verified Ripple Performance: Specified ripple currents at 120 Hz and 10 kHz give concrete, testable limits for both low- and high-frequency AC stress.
• Low Impedance for Better Transient Response: 32 mOhm impedance helps minimize voltage drop under load transients and improves regulator stability.
• Long Life at Elevated Temperature: 8 000-hour endurance at 105 °C (per series spec) supports extended field life in demanding thermal conditions.
• Through-Hole Simplicity: Radial lead, 7.5 mm spacing and standard can packaging simplify PCB layout and prototyping for repairable or serviceable designs.
