UVZ2C4R7MED

The UVZ2C4R7MED is a radial-lead aluminum electrolytic capacitor in Nichicon’s UVZ series, offering a 4.7 µF capacitance at a 160 V rating. Designed for general-purpose electronic applications, it provides a compact footprint (φ6.3 × 11 mm) with polarized radial leads and RoHS compliance.

Key performance attributes include a wide operating temperature range from −40°C to 105°C and a rated endurance of 1000 hours at 105°C, making it suitable where elevated-temperature stability and a high working voltage are required.

Key Features

• Electrical — Capacitance & Voltage: 4.7 µF nominal capacitance with a rated voltage of 160 V and capacitance tolerance of −20% to +20%.
• Loss Characteristics: Tangent of loss angle (tanδ) 0.20 measured at 20°C, 120 Hz, supporting predictable dissipation behavior in AC and ripple environments.
• Ripple Current Ratings: Low-frequency ripple current 34 mA at 120 Hz and high-frequency ripple current 54.4 mA at 10 kHz, specified for design consideration across frequency ranges.
• Leakage Current: Specified leakage current of 115.2 µA, useful for estimating standby and bias currents in circuits.
• Reliability & Endurance: Rated for 1000 hours at 105°C, with stable capacitance and dissipation characteristics over the specified endurance period.
• Mechanical — Compact Radial Package: Cylindrical can, size φ6.3 × 11 mm, radial lead spacing 2.5 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Environmental Compliance: RoHS compliant, meeting modern material-restriction requirements.

Typical Applications

• General Purpose Electronics: Suited for circuits that require a 160 V-rated, compact aluminum electrolytic for filtering, decoupling or energy storage where a radial-lead form factor is preferred.
• Power Conversion Modules: Applicable in power supply stages that need a small high-voltage capacitor with defined ripple current ratings across low and high frequencies.
• Control and Signal Circuits: Use in control boards and signal-conditioning assemblies where polarized electrolytic capacitance and a wide operating temperature range are required.

Unique Advantages

• High Working Voltage in a Small Package: 160 V rating combined with a φ6.3 × 11 mm can enables use where board space is limited but higher voltage capability is needed.
• Wide Operating Temperature Range: −40°C to 105°C rating supports deployment across a broad set of ambient conditions while maintaining performance.
• Defined Endurance at Elevated Temperature: 1000-hour rating at 105°C provides engineers a clear reliability target for thermal-stressed designs.
• Frequency-Aware Ripple Specifications: Provided ripple current values at 120 Hz and 10 kHz help in designing for both low-frequency and high-frequency ripple environments.
• Compact Radial Lead Form: 2.5 mm lead spacing (±0.5 mm) and standard radial can simplify through-hole assembly and mechanical mounting choices.
• Regulatory Compliance: RoHS compliance supports material-restricted product requirements.
