UPW2A4R7MDD

The UPW2A4R7MDD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon's UPW series. It is a radial-lead, polarized capacitor specified at 4.7 µF and 100 V, optimized for compact power applications.

With a small φ5 × 11 mm can, low-loss characteristics and a wide operating temperature range, this capacitor targets switching power supplies and automotive electronics where long-term stability and compact size are required.

Key Features

• Capacitance & Voltage: 4.7 µF capacitance rated for 100 V operation, suitable for higher-voltage filtering and decoupling tasks.
• Miniature Radial Package: φ5 × 11 mm can with radial lead mounting and 2 mm lead spacing (±0.5 mm), enabling dense PCB placement in compact power assemblies.
• High Reliability Construction: UPW series miniature aluminum electrolytic design with long endurance—specified for 2000 hours at 105°C—targeting demanding environments.
• Low Loss & Controlled Leakage: tanδ = 0.08 (measured at 20°C, 120 Hz) and specified leakage current of 14.1 µA, reducing dissipation and standby losses in power circuits.
• Ripple Current Performance: Low-frequency ripple current of 22.2 mA (120 Hz) and high-frequency ripple current of 74 mA (10 kHz), supporting smoothing and ripple reduction across frequencies.
• Wide Temperature Range: Rated for operation from −55°C to +105°C, supporting use across varied thermal environments.
• AEC-Q200 Rated: Meets AEC-Q200 qualification, making it suitable for automotive-grade electronic designs.
• Packaging Options: Available in bulk (no terminal forming) or bag packing to accommodate production and prototyping workflows.

Typical Applications

• Automotive Electronics: Use in electronic control modules and power subsystems where AEC-Q200 qualification and a wide temperature range are required.
• Switching Power Supplies: Miniature, low-impedance construction suited for output smoothing and decoupling in compact switch-mode power supplies.
• Power Filtering and Decoupling: High-voltage rating and controlled leakage make it appropriate for filtering and decoupling in compact power circuits.

Unique Advantages

• Compact footprint: φ5 × 11 mm can size enables space savings on densely populated PCBs without sacrificing voltage capability.
• High-voltage capability: 100 V rating permits use in higher-voltage sections of power systems that require electrolytic bulk capacitance.
• Automotive-grade qualification: AEC-Q200 rating and a wide −55°C to +105°C operating range support deployment in automotive environments.
• Stable performance at frequency: Specified tanδ and ripple current values at 120 Hz and 10 kHz provide predictable behavior across low and high-frequency power components.
• Endurance for sustained operation: 2000 hours at 105°C endurance rating provides designers with a clear long-term thermal performance expectation.
• Installation-friendly radial leads: Radial lead form and defined lead spacing simplify through-hole assembly and prototyping.
