UPJ2F470MHD

The UPJ2F470MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series, configured as a radial-lead can. It provides 47 µF capacitance at a 315 V rating in a compact φ18 × 35.5 mm can with 7.5 mm lead spacing.

Designed with low impedance characteristics and long-term endurance, this part is intended for general-purpose power applications and switching power-supply designs that require stable DC-link capacitance and extended high-temperature life.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with a 315 V rated voltage and tolerance of -20% to +20%, suitable for DC-link and power-filtering roles where higher voltage capability is required.
• Low-loss Performance: tanδ (dissipation factor) of 0.2 measured at 20°C, 120 Hz, indicating controlled losses for stable operation in power circuits.
• Ripple Current Capability: Specified low-frequency ripple current of 235 mA at 120 Hz and high-frequency ripple current of 376 mA at 200 kHz, supporting a range of switching and ripple conditions.
• High Reliability Endurance: Rated for 5000 hours life at 105°C, providing extended service life under elevated temperature and load conditions.
• Leakage Current: Measured leakage current of 692.2 µA, specified for predictable bias behavior after application of rated voltage.
• Robust Mechanical Package: Radial lead mounting in a φ18 can (L: 35.5 mm) with 7.5 mm lead spacing and lead spacing tolerance ±0.5 mm, enabling straightforward through-hole assembly and secure mechanical retention.
• Operating Temperature: Rated from -40°C to +105°C for a wide range of ambient conditions.
• Compliance & Packaging: RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.

Typical Applications

• Switching Power Supplies: Low-impedance construction and specified high-frequency ripple current make this capacitor suitable for DC-link and output filtering in switching regulators.
• Power Conversion Modules: Used for bulk energy storage and smoothing in AC/DC and DC/DC converter stages where 315 V rating is required.
• Industrial Power Systems: General-purpose filtering and decoupling in industrial power electronics that demand extended high-temperature endurance.

Unique Advantages

• High Voltage Capability: 315 V rating enables use in higher-voltage power designs where lower-voltage capacitors are insufficient.
• Extended High-Temperature Life: 5000 hours at 105°C supports longer maintenance intervals and predictable lifetime in hot operating environments.
• Versatile Ripple Handling: Specified ripple currents at both low and high frequencies accommodate a variety of switching frequencies and application needs.
• Compact Through-Hole Form Factor: φ18 radial can with standard lead spacing simplifies integration into legacy and through-hole assemblies.
• Design Predictability: Controlled tanδ and specified leakage current provide engineers with measurable parameters for thermal and ripple budgeting.
• RoHS Compliant Supply Options: Available in bulk or bag packing to match procurement and assembly workflows while meeting RoHS requirements.
