UVY1C103MHD

The UVY1C103MHD from Nichicon is a radial-leaded aluminum electrolytic capacitor rated 10,000 µF at 16 V with a ±20% tolerance. It is designed for general-purpose power supply filtering and bulk energy storage in through-hole assemblies.

Offering a wide operating temperature range of −55°C to 105°C and a 2000-hour endurance at 105°C, this component balances high capacitance and ripple-handling capability in a compact φ16 × 35.5 mm can with 7.5 mm lead spacing.

Key Features

• High Capacitance, Low Voltage: 10,000 µF at 16 V provides substantial bulk energy storage for smoothing and hold-up in low-voltage power rails.
• Wide Temperature Range: Rated for −55°C to 105°C to support operation across demanding thermal environments.
• Endurance: 2000 hours at 105°C, enabling reliable long-term performance under elevated temperature stress.
• Ripple Current Handling: 1.930 A at 120 Hz and 2.2195 A at 10 kHz, supporting both low- and high-frequency ripple conditions to reduce heating in operation.
• Loss Characteristics: tanδ of 0.38 measured at 20°C and 120 Hz, reflecting the device’s dissipation factor for high-value capacitance.
• Leakage Current: Specified leakage current of 4800 µA after rated voltage application, useful for system-level leakage budgeting.
• Mechanical & Mounting: Radial lead, polarized can with 7.5 mm lead spacing and φ16 × 35.5 mm dimensions for straightforward through-hole placement.
• Compliance & Packaging: RoHS compliant and available in bulk/bag packing; part is in mass production.

Typical Applications

• Power Supply Filtering: Bulk smoothing and ripple reduction on low-voltage DC rails where large capacitance is required.
• DC-DC Converter Output: Energy reservoir and output stabilization for converters and regulator circuits in industrial and consumer equipment.
• Backup Hold-Up: Temporary energy storage to maintain supply during short interruptions or transient loads.
• General-Purpose Through-Hole Designs: Suitable for PCB layouts that require radial-lead components and robust temperature endurance.

Unique Advantages

• Large Capacitance in a Compact Can: 10,000 µF in a φ16 × 35.5 mm package helps reduce board area compared with multiple smaller capacitors.
• Designed for Elevated Temperatures: 2000-hour endurance at 105°C provides predictable lifetime behavior for designs exposed to high operating temperatures.
• Dual-Frequency Ripple Capability: Specified ripple currents at both 120 Hz and 10 kHz allow designers to assess heating and derating across common ripple spectra.
• Through-Hole Reliability: Radial lead, polarized construction simplifies mounting and replacement in serviceable assemblies.
• Regulatory Compliance: RoHS-compliant construction aligns with modern environmental requirements for electronic products.
