UPW2E470MHD

The UPW2E470MHD is a radial-lead aluminum electrolytic capacitor designed for compact power applications. It delivers 47 µF capacitance at a 250 V rating in a φ16 × 25 mm can-style package, offering a combination of high-voltage handling and a small footprint.

Engineered for power conversion environments, this part provides low dissipation factor, defined ripple-current capability at both low and high frequencies, and extended endurance at elevated temperature, making it suitable for switching power supplies and automotive power systems where an AEC‑Q200 rated component is required.

Key Features

• Capacitance & Tolerance — 47 µF nominal with capacitance tolerance of −20% to +20% for predictable bulk energy storage.
• High Voltage Rating — Rated at 250 V to support higher-voltage DC link and power-conversion circuits.
• Dissipation Factor (tan δ) — tanδ 0.15 measured at 20°C, 120 Hz, supporting low-loss performance in filtering and decoupling roles.
• Ripple Current Capability — Specified low-frequency ripple current of 230 mA at 120 Hz and high-frequency ripple current of 368 mA at 10 kHz for both mains-frequency smoothing and higher-frequency switching noise attenuation.
• Leakage Current — Leakage current specified at 570 µA, allowing predictable standby and bias behavior in power designs.
• Reliability & Endurance — Rated endurance of 8000 hours at 105°C to support long-term operation under elevated temperature stress.
• Thermal Range — Operating temperature from −40°C to +105°C for use across a wide ambient range.
• Package & Mounting — Radial lead (can) construction, size φ16 × 25 mm, lead spacing 7.5 mm (±0.5 mm), supplied bulk or in bag packing.
• AEC‑Q200 Rated — Qualification stating suitability for applications requiring AEC‑Q200 level passive component reliability.
• Product Status — End Of Life (EOL).

Typical Applications

• Switching Power Supplies — Low impedance and defined ripple-current ratings make this capacitor suitable for bulk filtering and smoothing in switching regulators.
• Automotive Power Electronics — AEC‑Q200 rating and −40°C to +105°C operation support use in automotive electrical and power subsystems.
• High-Voltage DC Link and Power Conversion — 250 V rating enables use on higher-voltage DC rails for energy storage and transient suppression in converters.

Unique Advantages

• Compact high-voltage form factor: 47 µF at 250 V in a φ16 × 25 mm can provides space-efficient energy storage for constrained designs.
• Frequency-aware ripple handling: Separate ripple-current specifications at 120 Hz and 10 kHz allow designers to size capacitors for both low-frequency smoothing and high-frequency switching noise.
• Long high-temperature endurance: 8000 hours at 105°C gives quantifiable lifetime expectations for sustained thermal stress.
• Predictable loss characteristics: Specified tanδ at standard test conditions (20°C, 120 Hz) simplifies thermal and loss budgeting in power subsystems.
• AEC‑Q200 qualification: Provides a recognized reliability benchmark for integration into automotive-grade layouts and systems.
• Radial-lead convenience: Through-hole radial leads and standard 7.5 mm lead spacing ease prototyping, repair, and retrofit applications.
