UPW2DR47MED

The UPW2DR47MED is a miniature aluminum electrolytic capacitor in Nichicon's UPW series designed for low impedance and high reliability in switching power supply environments. It is a polarized, radial-lead can-style capacitor optimized for compact power and filtering applications.

Key value comes from its small footprint, end-to-end qualification for demanding applications (AEC-Q200), and specified performance across a −40 °C to 105 °C operating range with a rated lifetime at elevated temperature.

Key Features

• Capacitance & Voltage — 470 nF rated capacitance with a 200 V rated voltage for high-voltage filtering and decoupling tasks where a small capacitance and elevated voltage rating are required.
• Low Impedance / Ripple Capability — Specified ripple current of 12 mA at 120 Hz and 19.2 mA at 10 kHz supports switching-power filtering and decoupling at common frequencies.
• High Reliability / Automotive Grade — AEC-Q200 rating indicates qualification for applications requiring enhanced component reliability and traceability.
• Temperature & Lifetime — Operates from −40 °C to 105 °C with a rated lifetime of 2000 hours at 105 °C for predictable behavior in thermally stressed designs.
• Mechanical & Mounting — Radial lead, can package with 2.5 mm lead spacing and compact physical size (L: 1.1 × D: 0.63 cm) for tight board layouts and through-hole assembly.
• Tolerance & Polarization — Capacitance tolerance of −20% to +20% (±20%) and polarized construction; suitable where polarized electrolytic capacitors are required.

Typical Applications

• Switching Power Supplies — Low-impedance 470 nF capacitance and specified ripple current make this capacitor suitable for output filtering and decoupling in switching regulators.
• Automotive Electronics — AEC-Q200 rating and 105 °C temperature capability support use in automotive electronic modules requiring compliant passive components.
• Compact Power Modules — Small can footprint and radial-lead mounting fit compact DC‑DC converters, auxiliary power supplies, and board-level power conditioning.
• General Power Filtering — High-voltage rating and polarized design enable use in high-voltage filter circuits and bulk decoupling where small capacitance is required.

Unique Advantages

• Compact footprint: Small physical dimensions (L: 1.1 × D: 0.63 cm) reduce PCB area for space-constrained power designs.
• Elevated voltage rating: 200 V rating allows designs that require higher DC working voltage without increasing capacitance size.
• Designed for switching environments: Low-impedance construction plus specified ripple currents at 120 Hz and 10 kHz support effective filtering in switching power applications.
• Automotive-grade qualification: AEC-Q200 rating provides an extra level of qualification for suppliers and designers targeting automotive or similarly demanding markets.
• Thermal endurance: Rated for operation to 105 °C with a defined 2000‑hour lifetime at that temperature for reliable long-term performance under elevated temperatures.
• Through-hole radial package: Radial lead, can-style package with 2.5 mm lead spacing simplifies assembly and mechanical retention in through-hole processes.
