UPW1E470MDD

The UPW1E470MDD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPW series, designed for low-impedance, high-reliability applications. This polarized 47 µF, 25 V device delivers targeted performance for compact power stages and switching power supplies.

Key technical attributes include a wide operating temperature range (−55 °C to 105 °C), AEC-Q200 rating, and measurable ripple current capacity across low and high frequencies—making it suitable for demanding embedded and automotive-related electronics designs.

Key Features

• Capacitance & Voltage — 47 µF rated capacitance with a 25 V rated voltage and tolerance of −20% to +20% for predictable energy storage.
• Low Loss / AC Performance — tan δ = 0.14 measured at 20 °C, 120 Hz, supporting stable AC characteristics in filtering and decoupling applications.
• Ripple Current Capability — Specified low-frequency ripple current of 54 mA at 120 Hz and high-frequency ripple current of 180 mA at 10 kHz to handle switching and high-frequency noise.
• Leakage Current — Leakage current specified at 35.25 µA for predictable standby and idle behavior.
• Thermal & Endurance — Rated for operation from −55 °C to 105 °C with an endurance (life) of 2000 hours at 105 °C.
• Compact Radial Package — Miniature can (φ5 × 11 L) with radial lead mounting and 2 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• Automotive-Grade Reliability — AEC-Q200 rating for designs requiring automotive-grade component qualification.

Typical Applications

• Switching Power Supplies — Low-impedance design and defined ripple current ratings make it suitable for output smoothing and decoupling in switching regulators.
• Automotive Electronics — AEC-Q200 rating and wide temperature range support use in automotive control modules and power-distribution circuits.
• DC–DC Converters — Compact size and high-frequency ripple handling enable placement in tight converter layouts for energy storage and noise suppression.
• Embedded Power Systems — Polarized radial package and predictable leakage current are useful for board-level bulk decoupling in compact embedded devices.

Unique Advantages

• Small footprint for tight layouts: φ5 × 11 mm can size and 2 mm lead spacing allow placement in compact PCB areas without sacrificing capacitance.
• Measured high-frequency performance: Specified 180 mA ripple current at 10 kHz provides designers with quantifiable behavior for high-speed switching environments.
• Wide operating temperature: −55 °C to 105 °C range supports designs that encounter extreme ambient conditions.
• Automotive-grade qualification: AEC-Q200 rating supports use where component-level automotive qualification is required.
• Defined endurance: 2000 hours at 105 °C gives a clear lifetime expectation for thermal-stressed applications.
