UHD1H471MHD

The UHD1H471MHD is a radial-lead, polarized aluminum electrolytic capacitor from Nichicon’s UHD series. It delivers 470 µF capacitance at a 50 V rating with low dissipation factor and engineered high-ripple performance for general-purpose electronic designs.

Designed for applications that require compact, high-capacitance through-hole components, this part combines low tanδ, defined ripple-current capability at both low and high frequencies, and extended endurance up to 5000 hours at 105°C.

Key Features

• Electrical Performance — 470 µF nominal capacitance with a tolerance of -20% to +20% and rated voltage of 50 V, suitable where a polarized aluminum electrolytic is required.
• Low Loss (tan δ) — Dissipation factor (tanδ) of 0.10 measured at 20°C, 120 Hz, supporting stable AC performance and reduced heating under ripple conditions.
• High Ripple Current Capability — Specified low-frequency ripple current of 1.5375 A at 120 Hz and high-frequency ripple current of 2.05 A at 100 kHz, reflecting the UHD series’ high-ripple design.
• Mechanical & Packaging — Radial lead (can) package with case size φ12.5 × 20L mm, lead spacing 5.0 mm (±0.5 mm), and available in bulk or bag packing.
• Temperature & Endurance — Rated for operation from -40°C to +105°C with an endurance rating of 5000 hours at 105°C under rated ripple and DC bias conditions.
• Leakage Current — Specified leakage current of 235 µA (measured after the defined application of rated voltage at 20°C), consistent with series specifications for reliability.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• General Purpose Electronics — For designs that call for a 470 µF, 50 V polarized radial electrolytic capacitor with through-hole mounting and reliable general-purpose performance.
• High-Ripple / High-Frequency Circuits — Suited to circuits where lower impedance at higher frequencies and elevated ripple-current handling are required, supported by the UHD series’ high-ripple characteristics and the part’s specified ripple currents.
• Elevated-Temperature Endurance — Appropriate for assemblies that must withstand extended operation at higher ambient temperatures, backed by a 5000-hour rating at 105°C.

Unique Advantages

• Compact high-capacitance through-hole form: φ12.5 × 20 mm case delivers 470 µF in a small radial-can footprint for space-constrained assemblies.
• Measurable low-loss behavior: tanδ = 0.10 (20°C, 120 Hz) helps limit dissipation and thermal rise when operating under AC ripple.
• Dual-frequency ripple capability: Rated ripple currents at both 120 Hz and 100 kHz provide clear, verifiable performance points for low- and high-frequency applications.
• Long endurance at high temperature: 5000 hours at 105°C supports longevity in sustained thermal environments and enables predictable life planning.
• Through-hole robustness: Radial-lead construction with defined lead spacing (5.0 mm ±0.5 mm) simplifies PCB placement and soldering for manual or wave assembly processes.
• Production-ready availability: RoHS compliant and listed as mass production stock, facilitating procurement and BOM planning.
