UHV1C472MHD

The UHV1C472MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHV series, engineered for low impedance and high ripple current performance. It delivers 4700 µF capacitance at 16 V in a compact φ16 × 25 mm can, intended for general-purpose electronics that require robust bulk capacitance and high-frequency performance.

Key Features

• Capacitance & Voltage: 4700 µF nominal capacitance with a rated voltage of 16 V and tolerance of -20% to +20%, providing substantial energy storage for low-voltage systems.
• Low Impedance: Specified impedance of 33 mΩ for reduced AC voltage drop and improved high-frequency behavior.
• High Ripple Current: Rated ripple current of 3.392 A at 120 Hz and 3.99 A at 100 kHz (high-frequency), enabling sustained operation under AC stress.
• Dissipation Factor (tan δ): Dissipation factor (DF) of 0.21 measured at 20°C, 120 Hz, reflecting the capacitor’s loss characteristics under standard test conditions.
• Leakage Current: Measured leakage current of 752 µA after 2 minutes at 20°C under rated voltage.
• Reliability & Lifetime: Endurance rated for 6000 hours at 105°C with defined limits for capacitance change, tan δ, and leakage current.
• Operating Temperature: Wide operating range from -40°C to +105°C for deployment across varied thermal environments.
• Mechanical & Mounting: Radial lead, polarized can with lead spacing of 7.5 mm (±0.5 mm) and bulk/bag packing options; designed for through-hole radial mounting.
• Compliance: RoHS compliant as stated in the product data.

Typical Applications

• General-purpose electronic circuits: Use where a high-capacitance, low-impedance polarized capacitor is required for energy storage or smoothing.
• Circuits requiring high ripple handling: Suitable for designs that subject capacitors to elevated ripple currents thanks to its specified ripple current ratings.
• High-frequency decoupling scenarios: The UHV series design focuses on lower impedance at higher frequencies, making this part appropriate where improved HF performance is beneficial.

Unique Advantages

• Substantial bulk capacitance: 4700 µF provides significant charge storage for load transients and bulk energy buffering.
• Quantified ripple capability: Clear ripple current specifications at both low (120 Hz) and high (100 kHz) frequencies let designers size capacitors to handle expected AC stress.
• Measured loss characteristics: Specified dissipation factor (DF = 0.21 at 20°C, 120 Hz) gives a concrete indicator of AC losses for power-budgeting and thermal considerations.
• Extended high-temperature endurance: 6000-hour life at 105°C delivers predictable long-term performance in elevated-temperature applications.
• Compact radial package: φ16 × 25 mm can with radial leads and 7.5 mm lead spacing provides a balance of density and through-hole robustness for PCB layouts.
• RoHS compliant: Conforms to RoHS requirements for regulatory and environmental compliance in assemblies.
