UHW1J470MED

The UHW1J470MED is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHW series, designed for miniature, high-ripple-current applications. It delivers 47 µF capacitance at a 63 V rating with a compact φ6.3 × 11 mm can and radial mounting for through-hole assemblies.

Targeted at general-purpose electronics, this part combines high-frequency performance (lower impedance at high frequency), elevated ripple handling, and long endurance for designs that require compact power filtering and reliable operation across –40°C to 105°C.

Key Features

• Capacitance & Tolerance — 47 µF nominal with tolerance of –20% to +20% (measured at 120 Hz, 20°C).
• Voltage Rating — Rated for 63 V DC operation.
• Dissipation Factor (tan δ) — tan δ = 0.09 (measured at 20°C, 120 Hz at 63 V), indicating low loss under the stated test conditions.
• Ripple Current Capability — Low-frequency ripple current 200 mA at 120 Hz and high-frequency ripple current 500 mA at 10 kHz (frequency-dependent coefficients apply).
• Leakage Current — Specified leakage current 29.61 µA (after rated voltage application conditions per product test).
• Endurance & Temperature — Rated life 8000 hours at 105°C; operating temperature range –40°C to +105°C.
• Package & Mounting — Radial lead can, case size φ6.3 × 11 mm, lead spacing 2.5 mm (±0.5 mm); supplied bulk/no terminal forming or bag packing.
• Polarized Device — Designed for polarized DC applications.
• RoHS Compliance — Product is RoHS compliant.
• Product Status — End Of Life. Verify availability and lead time when requesting quotes.

Typical Applications

• Power supply filtering — Compact decoupling and smoothing for DC rails where space is limited and 63 V rating is required.
• High-frequency ripple handling — Suitable for circuits that require lower impedance at higher frequencies, leveraging the UHW series’ high-frequency characteristics and rated 500 mA ripple at 10 kHz.
• General-purpose electronics — Through-hole implementations in consumer or industrial equipment that use radial-can capacitors for reliable bulk capacitance within –40°C to 105°C operating range.

Unique Advantages

• Compact footprint: φ6.3 × 11 mm radial can reduces board space while providing 47 µF of capacitance for dense assemblies.
• High ripple tolerance: Defined ripple current ratings at both 120 Hz and 10 kHz enable clearer specification for AC-stressed power rails.
• Low dissipation factor at rated conditions: tan δ = 0.09 at 63 V, 120 Hz (20°C) supports efficient energy handling with controlled losses.
• Wide operating temperature: –40°C to 105°C rating allows deployment across a broad range of environmental conditions.
• Long endurance: 8000 hours at 105°C provides a predictable lifetime specification for thermal-stressed designs.
• RoHS compliant: Meets environmental substance restrictions for regulated markets.
