UPZW6470MHD

The UPZW6470MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UPZ series, offering 47 µF capacitance at a 420 V rating. Designed for general-purpose high-voltage circuits, it combines a compact φ12.5 × 35.5 mm can, polarized radial lead mounting and measurable ripple performance for power-filtering and smoothing duties.

Key value comes from its high working voltage, controlled loss tangent (tan δ), defined ripple current ratings at both low and high frequencies, and a 2000-hour endurance rating at 105°C for robust thermal reliability in demanding installations.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance rated for 420 V DC, suitable for high-voltage smoothing and energy storage in compact assemblies.
• Loss Characteristic — tan δ (loss tangent) of 0.20 measured at 20°C, 120 Hz, providing a defined dissipation characteristic for design calculations.
• Ripple Current Capability — Rated ripple currents of 360 mA at 120 Hz (low frequency) and 540 mA at 10 kHz (high frequency), enabling specification for both mains-frequency and higher-frequency ripple environments.
• Leakage Current — Leakage current of 889.6 µA measured per datasheet condition (after 1 minute application of rated voltage at 20°C), allowing predictable standby loss budgeting.
• Thermal Endurance — Life rating of 2000 hours at 105°C under DC bias plus rated ripple current, with post-test limits defined for capacitance change, tan δ and leakage current.
• Package & Mounting — Radial can package (φ12.5 × 35.5 mm) with 5 mm lead spacing (±0.5 mm) and bulk/bag packing options for straightforward through-hole assembly.
• Operating Range — Specified for operation from −40°C to +105°C, matching the UPZ series category temperature range.

Typical Applications

• General-purpose power filtering — Use in high-voltage DC filter stages where 420 V rating and 47 µF capacitance provide bulk energy storage and ripple attenuation.
• High-voltage power supplies — Suitable for smoothing and decoupling in power supplies that require defined ripple performance at both 120 Hz and higher switching frequencies.
• Industrial electronics — Fits compact through-hole designs needing a compact high-voltage capacitor with specified endurance at elevated temperature.

Unique Advantages

• High working voltage: 420 V rating enables direct use in higher-voltage rail designs without series stacking.
• Measured loss and leakage figures: Specified tan δ and a calculable leakage current (889.6 µA per datasheet condition) help with thermal and standby-loss budgeting.
• Frequency-aware ripple specs: Separate low-frequency and high-frequency ripple current ratings (360 mA at 120 Hz, 540 mA at 10 kHz) assist in selecting the capacitor for both line-frequency and switching environments.
• Compact radial form factor: φ12.5 × 35.5 mm can with 5 mm lead spacing fits space-constrained through-hole assemblies while keeping leaded mounting simplicity.
• Proven endurance: 2000 hours at 105°C under rated stress gives a clear reliability baseline for lifetime planning.
• Manufacturer support: Nichicon UPZ series pedigree provides consistent dimensional and performance data across related voltages and capacitances for design scaling.
