UPW1E4R7MDD

The UPW1E4R7MDD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UPW series. It delivers 4.7 µF capacitance at a 25 V rating in a compact φ5 × 11 mm can, optimized for low impedance and high-reliability power applications.

Targeted use cases include switching power supplies and compact power modules where tight temperature performance, controlled leakage and defined ripple handling are required. The component combines a wide operating temperature range and AEC-Q200 qualification for designs that require validated reliability.

Key Features

• Capacitance and Voltage: 4.7 µF nominal capacitance with a 25 V rated voltage and tolerance of -20% to +20%.
• Miniature Radial Can: Compact φ5 × 11 mm can with 2.0 mm lead spacing (±0.5 mm), suited for through-hole radial mounting and tight board layouts.
• Low Loss (tan δ): Tan δ (DF) 0.14 measured at 20°C, 120 Hz for the 25 V rating, supporting stable AC performance at switching frequencies.
• Ripple Current Capability: Low-frequency ripple current 54 mA at 120 Hz and high-frequency ripple current 180 mA at 10 kHz, enabling smoothing and decoupling in power circuits.
• Leakage Current: Rated leakage current of 4 µA, useful for power-sensitive designs where minimal DC loss is important.
• Temperature and Endurance: Operating temperature range from -55°C to +105°C with a rated life/endurance of 2000 hours at 105°C.
• AEC-Q200 Qualified: Series-rated AEC-Q200, providing qualification suitable for designs that require that level of reliability verification.
• Packaging: Supplied in bulk (no terminal forming) or bag packing to accommodate a range of assembly and stocking workflows.
• Polarized Electrolytic: Polarized aluminum electrolytic construction for standard DC power applications.

Typical Applications

• Switching Power Supplies: Decoupling and output smoothing in compact switch-mode power supply stages where low impedance and high-frequency ripple handling matter.
• Automotive Electronics: Power filtering and stabilization in automotive modules where AEC-Q200 qualification and wide temperature range are required.
• Power Management Modules: Local energy storage and transient suppression in compact power modules and power rails.

Unique Advantages

• Compact footprint: φ5 × 11 mm can and 2 mm lead spacing reduce board area for dense designs.
• Validated reliability: AEC-Q200 series qualification and 2000-hour endurance at 105°C support deployment in demanding thermal environments.
• Broad temperature range: Operates from -55°C to +105°C to meet varied environmental requirements.
• Measured low loss: Tan δ 0.14 at standard test conditions (20°C, 120 Hz) for predictable AC behavior in filtering applications.
• High-frequency ripple capability: 180 mA ripple rating at 10 kHz helps maintain performance in high-switching-frequency circuits.
• Low leakage: 4 µA leakage current minimizes DC loss in power-sensitive applications.
