UVK2C470MPD

The UVK2C470MPD is a miniature-sized aluminum electrolytic capacitor from Nichicon's UVK series, supplied in a radial lead can. It delivers 47 µF nominal capacitance at a 160 V rated voltage with a compact φ10 × 20 mm case and 5 mm lead spacing.

Designed for general-purpose applications, the UVK2C470MPD combines a wide operating temperature range (−40 °C to 85 °C) and a 2000-hour endurance at 85 °C, providing reliable performance where space and thermal endurance are important. The series is compliant with the RoHS directive.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with a 160 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Miniature Radial Package: Radial lead can package, size φ10 × 20 mm with 5 mm lead spacing (±0.5 mm), suitable for through-hole assembly and compact assemblies.
• Temperature & Endurance: Operates from −40 °C to 85 °C and meets endurance specifications after 2000 hours at 85 °C with capacitance change within ±20% and leakage current within initial limits.
• Loss Characteristics: Tangent of loss angle (tan δ) specified as 0.20 at 120 Hz, 20 °C for this rated voltage, supporting predictable AC performance.
• Ripple Current Handling: Low-frequency ripple: 210 mA at 120 Hz; high-frequency ripple: 336 mA at 10 kHz, enabling effective smoothing in varying ripple environments.
• Leakage Current & Polarization: Polarized electrolytic design with specified leakage current of 400.8 µA, measured per the product’s test conditions.
• Packaging Options: Available in bulk (no terminal forming) and bag packing; product is in mass production.

Typical Applications

• General-purpose power filtering: Suitable where a 47 µF, 160 V polarized capacitor is required for decoupling or smoothing in power systems within the specified temperature range.
• Through-hole assemblies: Radial lead format and compact φ10 × 20 mm size make it suitable for space-constrained through-hole PCBs.
• Applications requiring moderate ripple handling: Use in circuits where the specified 120 Hz and 10 kHz ripple current ratings (210 mA and 336 mA) meet the system demands.

Unique Advantages

• Compact footprint: φ10 × 20 mm case provides a smaller alternative while retaining 47 µF at 160 V, helping reduce board area.
• Specified long-term endurance: 2000 hours at 85 °C with defined post-test limits ensures predictable aging and service life in thermal stress conditions.
• Clear AC performance metrics: Defined tan δ at 120 Hz and ripple current ratings at 120 Hz and 10 kHz enable straightforward thermal and reliability calculations.
• Polarized design for high-voltage DC: 160 V rating suits DC energy storage and smoothing roles in medium-voltage circuits.
• RoHS compliant series: Part of the UVK series that is compliant with RoHS (2011/65/EU, (EU)2015/863), supporting regulatory requirements.
• Flexible packing: Bulk or bag packing options simplify procurement for prototype runs or production quantities.
