URZ2G470MHD

The URZ2G470MHD is a radial lead aluminum electrolytic capacitor from Nichicon’s URZ series, designed for general-purpose power filtering and energy-storage in through-hole assemblies. It combines a 47 µF capacitance with a 400 V rating in a compact, low-profile can suitable for space-constrained designs.

Engineered with defined ripple and leakage characteristics and a 1000-hour endurance at elevated temperature, this component is intended for applications that require reliable DC bus smoothing and decoupling up to 105°C.

Key Features

• Capacitance and Tolerance — 47 µF nominal with a capacitance tolerance of −20% to +20% for predictable charge storage and timing behavior.
• High DC Voltage — 400 V rated voltage for use on higher-voltage DC buses and power rails.
• Loss Characteristic (tan δ) — Specified tan δ of 0.25 measured at 20°C and 120 Hz at the rated voltage, enabling designers to assess dissipation and heating.
• Ripple Current Ratings — Low-frequency ripple current of 300 mA at 120 Hz and high-frequency ripple current of 480 mA at 10 kHz, supporting both mains-frequency and switching environments.
• Leakage Current — Specified leakage current of 852 µA to aid in power-loss budgeting and standby calculations.
• Temperature and Endurance — Operating temperature range −40°C to 105°C with a life rating of 1000 hours at 105°C for thermal reliability planning.
• Package and Mounting — Radial lead (can) package, dimensions φ18 × 25 mm, lead spacing 7.5 mm (±0.5 mm), supplied in bulk/bag packing for through-hole assembly.
• Polarized Design — Polarized electrolytic construction for DC applications requiring polarity-aware energy storage.

Typical Applications

• High-voltage power supplies — Input and output smoothing on 400 V DC rails where compact through-hole capacitors are needed.
• Industrial control electronics — Decoupling and energy storage in general-purpose control and power circuitry operating up to 105°C.
• Through-hole assemblies and prototypes — Radial-lead form and bulk packaging make the part suitable for hand-assembled or wave-soldered boards.

Unique Advantages

• 400 V rating for higher-voltage designs: Enables use on elevated DC bus voltages without resorting to multiple lower-voltage capacitors in series.
• Compact, low-profile can: φ18 × 25 mm footprint helps preserve board space in constrained layouts while providing necessary capacitance.
• Dual ripple specifications: Defined ripple current at both 120 Hz and 10 kHz supports designers working across mains-frequency and switching-frequency domains.
• Clear electrical parameters: Specified tan δ and leakage current values allow accurate thermal and loss budgeting during design.
• Through-hole convenience: Radial leads and standard 7.5 mm spacing simplify placement into legacy and mechanically robust PCBs.
• Elevated-temperature endurance: 1000-hour rating at 105°C offers a quantifiable reliability metric for thermal stress planning.
