UPW2E4R7MPD

The UPW2E4R7MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPW series, delivering a compact 4.7 µF capacitance at a 250 V rating. It is a miniature, low-impedance design intended for power conversion and switching power supply applications where compact size and dependable ripple handling matter.

Engineered for operation from -40°C to 105°C with a 5000-hour endurance at 105°C and an AEC-Q200 rating, this polarized radial can targets applications that require stable performance under elevated temperature and continuous DC bias conditions.

Key Features

• Capacitance & Voltage: 4.7 µF nominal capacitance rated at 250 V, with tolerance -20% to +20%.
• Low-loss Performance: tanδ = 0.15 measured at 20°C, 120 Hz — suited for low-impedance power circuits.
• Ripple Current Capability: 50 mA at 120 Hz (low frequency) and 80 mA at 10 kHz (high frequency) for handling AC ripple in power stages.
• Leakage Current: Specified leakage current of 147 µA, enabling predictable bias behavior in DC circuits.
• Thermal and Endurance Rating: Operating temperature range -40°C to 105°C with a life rating of 5000 hours at 105°C.
• Packaging & Mounting: Radial lead (polarized) can, size φ10 × 12.5 mm, lead spacing 5.0 mm (±0.5 mm), available in bulk or bag packing.
• Qualification: AEC-Q200 rating included in product specifications.
• Product Status: End Of Life.

Typical Applications

• Switching Power Supplies: Compact radial form factor and low impedance make it suitable for output and input filtering in switching regulators and DC–DC converters.
• Power Conversion Modules: Supports ripple filtering and bulk decoupling in compact power modules where 250 V working voltage is required.
• Automotive Electronics: With an AEC-Q200 rating and -40°C to 105°C operating range, it can be used in vehicle electronic subsystems that require qualified passive components.
• Industrial Control: Useful for DC bus and control power filtering in industrial equipment operating at elevated temperatures.

Unique Advantages

• High working voltage: 250 V rating provides headroom for higher-voltage power applications and filtering tasks.
• Compact radial can: φ10 × 12.5 mm package with 5 mm lead spacing enables dense board layouts while maintaining through-hole mounting reliability.
• Frequency-aware ripple handling: Specified ripple currents at both 120 Hz and 10 kHz support effective filtering across low and high frequency components.
• Proven endurance at elevated temperature: 5000 hours at 105°C gives designers a quantifiable lifetime figure for thermal stress planning.
• Qualified to AEC-Q200: Inclusion of the AEC-Q200 rating supports use in applications requiring recognized component qualification standards.
• Predictable leakage characteristics: Specified leakage current (147 µA) aids in bias and hold-up time calculations for power rails.
