UHE1E472MHD

The UHE1E472MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can. It provides 4700 µF capacitance at a 25 V rating with low impedance and elevated ripple handling for general-purpose electronic designs.

Engineered for long-life operation, this radial-lead UHE series part supports continuous operation up to 105°C with a specified endurance of 10,000 hours at 105°C, making it suitable for designs that require sustained performance in elevated-temperature environments.

Key Features

• High Capacitance — 4700 µF nominal capacitance (4.7 mF) for bulk energy storage and decoupling in power rails.
• Rated Voltage — 25 V working voltage suitable for many low-voltage power supply rails.
• Low Impedance — Measured impedance of 38 mΩ supports efficient ripple attenuation and transient response.
• High Ripple Current Capability — 3.264 A at 120 Hz (low frequency) and 4.08 A at 10 kHz (high frequency) for continuous ripple handling in switching power applications.
• Long Life Endurance — 10,000 hours rated life at 105°C under DC bias plus rated ripple, aligned with the UHE series’ high-reliability design.
• Temperature Range — Operating from −40°C to +105°C to accommodate a wide range of thermal environments.
• Compact Radial-Lead Package — Case size φ16 × 40 mm length with 7.5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assembly; available in bulk (no terminal forming) and bag packing.
• Polarized Electrolytic — Polarized construction for traditional electrolytic capacitor applications; capacitance tolerance −20% to +20%.
• Leakage and Dissipation — Specified leakage current of 1175 µA and a loss tangent (tan δ) of 0.2 measured at 20°C, 120 Hz for predictable electrical behavior.
• RoHS Compliant — Meets RoHS requirements for non-restricted use in compliant assemblies.

Typical Applications

• General Purpose Electronics — Fits a broad range of general-purpose designs that require a 4700 µF capacitor in a radial-lead form factor.
• Power Supply Filtering — Supports bulk filtering and smoothing on 25 V power rails with substantial ripple current capacity and low impedance.
• Embedded and Industrial Equipment — Designed for long-life operation up to 105°C, suitable for embedded boards and industrial electronics requiring sustained reliability.

Unique Advantages

• Proven Long-Life Performance — 10,000-hour endurance at 105°C gives design confidence for sustained thermal stress scenarios.
• High Ripple Handling — Dual-spec ripple current ratings (120 Hz and 10 kHz) provide clear, frequency-aware guidance for power designs.
• Low-Impedance Solution — 38 mΩ impedance supports improved transient response and reduced voltage ripple on DC rails.
• Compact Miniature Can — φ16 × 40 mm packaging balances capacitance and board-space economy for through-hole assemblies.
• Clear Electrical Parameters — Specified leakage current (1175 µA) and tan δ (0.2 at 20°C, 120 Hz) help simplify design margin calculations.
• RoHS Compliance — Facilitates integration into RoHS-directed manufacturing flows.
