UPW1A470MDD

The UPW1A470MDD is a miniature, low-impedance aluminum electrolytic capacitor in Nichicon’s UPW series, specified at 47 µF and 10 V. It is a polarized radial-lead component optimized for compact power applications where low-loss filtering and high-frequency ripple handling are required.

Designed with a wide operating temperature range of −55°C to +105°C and a rated lifetime of 2000 hours at 105°C, this part addresses performance and reliability needs in space-constrained DC‑DC converters, switching power supplies and other power-management modules. It carries an AEC‑Q200 rating for automotive-grade reliability within its stated specifications.

Key Features

• Capacitance & Voltage — 47 µF rated capacitance at 10 V with ±20% tolerance for predictable decoupling and bulk energy storage.
• Low Loss — Specified tan δ of 0.19 (at 120 Hz, 20°C) to minimize dissipation in AC and ripple environments.
• High Ripple Capability — Rated ripple currents of 54 mA at 120 Hz and 180 mA at 10 kHz for effective filtering across low and high frequency ranges.
• Low Leakage — Leakage current specified at 14.1 µA, supporting low-standby and precision power designs.
• Temperature & Endurance — Operational range −55°C to +105°C with a lifetime rating of 2000 hours at 105°C to meet elevated-temperature use cases.
• Compact Radial Package — φ5 × 11 mm can with 2 mm lead spacing and radial lead mounting for easy through-hole assembly and dense PCB layouts.
• Automotive-Grade Qualification — AEC‑Q200 rated, suitable for designs requiring automotive-grade component qualification within the stated limits.
• Mounting & Packing — Radial lead, can-type package supplied in bulk/bag packing (no terminal forming), suitable for manual or automated through-hole assembly workflows.

Typical Applications

• Switching Power Supplies — Local bulk and output filtering in compact SMPS modules, leveraging low impedance and high-frequency ripple handling.
• DC‑DC Converters — Decoupling and energy storage for board‑level converters where a small footprint and reliable performance at elevated temperatures are required.
• Automotive Electronics — Power filtering in automotive electronic subsystems that require AEC‑Q200 qualified components and operation across −55°C to +105°C.
• Embedded and Industrial Controls — Stable passives for power-conditioning in controllers and modules operating in harsh temperature environments.

Unique Advantages

• Compact footprint: φ5 × 11 mm can and 2 mm lead spacing enable placement in tight layouts without sacrificing capacitance.
• Broad frequency performance: Distinct ripple ratings at 120 Hz and 10 kHz demonstrate suitability for both low- and high-frequency filtering tasks.
• Temperature and endurance balance: −55°C to +105°C range with 2000 h life at 105°C provides a predictable specification for thermal-stressed designs.
• Automotive-ready: AEC‑Q200 rating offers confidence for use in automotive applications within the capacitor’s specified limits.
• Low leakage and loss: 14.1 µA leakage and 0.19 tan δ reduce standby drain and thermal dissipation in sensitive circuits.
• Through-hole robustness: Radial lead package simplifies prototyping, repairability, and mechanical durability in vibration-prone environments.
