UPJ1V471MPD

The UPJ1V471MPD is a radial-lead aluminum electrolytic capacitor (470 µF, 35 V) from Nichicon's UPJ series, designed for general-purpose power applications and switching power supplies. It delivers low impedance and long-term reliability with an endurance rating of 5000 hours at 105°C, making it suitable for sustained ripple and bias conditions in power conversion circuits.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low Loss Characteristic: tanδ 0.12 specified at 20°C, 120 Hz for the 35 V rating, supporting stable performance under AC ripple.
• Ripple Current Capability: Low-frequency ripple current 700.6 mA (120 Hz) and high-frequency ripple current 1.13 A (200 kHz), enabling effective smoothing in switching regulators.
• Leakage Current: Leakage current measured at 493.5 µA, suitable for general-purpose power applications where predictable leakage is required.
• Long Endurance: Rated life of 5000 hours at 105°C (per series specifications), providing durability in elevated-temperature environments.
• Wide Temperature Range: Operates from −55°C to +105°C, supporting a broad range of operating environments.
• Radial Lead Package: φ10 × 30.5 mm can with 5 mm lead spacing (±0.5 mm), radial mounting for through-hole assemblies; available in bulk (no terminal forming) and bag packing.
• RoHS Compliant: Conforms to RoHS requirements as indicated in the product data.

Typical Applications

• Switching Power Supplies: Low impedance and rated ripple current make this capacitor well suited for input/output filtering and smoothing in SMPS designs.
• Power Conversion Modules: Used for bulk energy storage and decoupling in DC–DC converters and power regulators operating up to 35 V.
• Industrial and Consumer Electronics: General-purpose power filtering in control boards, instrumentation, and consumer devices requiring stable capacitance over temperature.

Unique Advantages

• Engineered for Low Impedance: The UPJ series specification calls out low impedance behavior, improving ripple attenuation in high-frequency switching environments.
• High Ripple Handling: Specified ripple current ratings at both low and high frequencies (700.6 mA at 120 Hz; 1.13 A at 200 kHz) support demanding power-supply filtering tasks.
• Extended High-Temperature Life: 5000-hour endurance at 105°C provides predictable ageing and reliability for designs with elevated operating temperatures.
• Wide Operating Range: −55°C to +105°C temperature range enables use across diverse environments and thermal conditions.
• Through-Hole Convenience: Radial lead can with 5 mm lead spacing and standard sleeve marking simplifies assembly and inspection in through-hole PCB designs.
• Regulatory Compliance: RoHS compliance supports inclusion in products targeting restricted-substance requirements.
