PLS1A471MDO1

The PLS1A471MDO1 is a radial-lead conductive polymer aluminum solid electrolytic capacitor in the Nichicon PLS series, engineered for long life and ultra-low ESR performance. It delivers 470 µF nominal capacitance at a 10 V rating with high ripple-current capability and a wide operating temperature range.

Designed for general-purpose power applications, this part combines low impedance (8 mΩ at 100 kHz) and robust endurance (5000 hours at 105°C) for demanding smoothing and decoupling tasks. This product is scheduled to be discontinued and is not recommended for new designs.

Key Features

• Capacitance & Voltage: 470 µF rated capacitance at 10 V for energy storage and bulk decoupling in low-voltage power rails.
• Ultra-low ESR: ESR of 8 mΩ measured at 100 kHz, minimizing voltage drop and heat under high-frequency ripple conditions.
• High Ripple Current: Rated for 2.75 A at 120 Hz and 5.5 A at 100 kHz, enabling effective ripple handling in switching power supplies and converters.
• Long Life Endurance: Load life specified at 5000 hours at 105°C, supporting sustained operation in elevated-temperature environments.
• Temperature Range: Serviceable from −55°C to +105°C for broad environmental coverage.
• Radial Package & Mounting: Radial, can-style package with 5 mm lead spacing for through-hole assemblies and lead-free flow soldering compatibility.
• Polarized Electrolyte: Polar capacitor construction with ±20% capacitance tolerance.
• Environmental Compliance: RoHS compliant and designed to meet lead-free flow soldering conditions.

Typical Applications

• General-purpose power filtering: Bulk smoothing and energy storage on low-voltage rails where 470 µF and 10 V are required.
• Switch-mode power supplies: Output decoupling and ripple suppression leveraging the capacitor's low ESR and high ripple-current ratings.
• DC-DC converters: Local energy reservoir for converters that demand compact, high-ripple tolerance components.

Unique Advantages

• Low thermal losses: Ultra-low ESR (8 mΩ at 100 kHz) reduces self-heating under ripple, improving reliability in high-frequency applications.
• High ripple tolerance: 5.5 A at 100 kHz and 2.75 A at 120 Hz allow smaller capacitor counts for equivalent ripple handling.
• Extended high-temperature life: 5000-hour rating at 105°C supports longer service intervals in thermally stressed designs.
• Through-hole robustness: Radial lead, can-style package and lead-free flow soldering compatibility simplify assembly for legacy and industrial boards.
• Wide operating range: −55°C to +105°C temperature capability covers harsh environments and broad deployment scenarios.

Why Choose PLS1A471MDO1?
