UHE1H4R7MDD

The UHE1H4R7MDD is a radial-lead aluminum electrolytic capacitor from Nichicon's UHE series. It provides 4.7 µF capacitance at a 50 V rating in a compact φ5 × 11 mm can with 2.0 mm lead spacing.

Designed as a general-purpose, miniature radial capacitor, the part combines series characteristics—low impedance and high reliability—with specifications suited to a wide range of electronics where a compact, polarized electrolytic is required.

Key Features

• Capacitance & Voltage: 4.7 µF rated capacitance at 50 V suitable for general-purpose circuit requirements.
• Radial Lead Package: Miniature radial can package (φ5 × 11 mm) with 2.0 mm lead spacing and 0.5 mm lead-spacing tolerance for through-hole assemblies.
• Low Dissipation Factor: tanδ (DF) = 0.1 measured at 20°C, 120 Hz, indicating controlled loss for stable AC performance.
• Ripple Current Capability: Specified low-frequency ripple current 48.4 mA at 120 Hz and high-frequency ripple current 88 mA at 10 kHz to support AC ripple handling in supply circuits.
• Low Leakage: Leakage current specified as 3 µA, supporting low-standby and precision circuits where minimal leakage is important.
• Extended Endurance: Rated for 5000 hours at 105°C, delivering long-term stability under elevated-temperature conditions.
• Wide Temperature Range: Operating from −40°C to +105°C to accommodate typical industrial and consumer operating environments.
• RoHS Compliant: Meets RoHS requirements as noted in product data.

Typical Applications

• General-purpose electronic circuits: Use where a compact, polarized aluminum electrolytic is specified for bulk capacitance in through-hole designs.
• Power supply subcircuits: Suitable for local supply smoothing and ripple attenuation in compact assemblies that require a 4.7 µF / 50 V capacitor.
• Industrial and consumer devices: Applicable in control and interface circuitry that operate across −40°C to +105°C and benefit from long endurance.

Unique Advantages

• Compact radial form factor: φ5 × 11 mm can size with 2.0 mm lead spacing fits constrained PCB real estate while remaining compatible with through-hole assembly.
• Measured AC performance: Low DF (0.1 at 120 Hz) and specified ripple currents at both low and high frequencies provide predictable behavior under AC stress.
• Low leakage current: 3 µA leakage supports designs that require minimal parasitic current draw.
• High-temperature endurance: Rated 5000 hours at 105°C for extended service life in elevated-temperature environments.
• RoHS compliance: Enables use in products that require lead-free manufacturing and compliance with RoHS directives.
• Simple packaging options: Available in bulk (no terminal forming) or bag packing to accommodate various production workflows.
