UPJ2A470MPD

The UPJ2A470MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series, designed for low-impedance, high-reliability applications. It delivers 47 µF capacitance at a 100 V rating in a compact φ10 × 20 mm can with 5.0 mm lead spacing.

Targeted at general-purpose electronics and switching power supply designs, this capacitor combines long endurance (5,000 hours at 105°C) and low loss characteristics for robust power filtering and decoupling in through-hole assemblies.

Key Features

• Capacitance and Voltage — 47 µF nominal capacitance with ±20% tolerance and a 100 V rated voltage for higher-voltage power rails.
• Low Loss (tan δ) — tanδ (DF) of 0.08 measured at 20°C, 120 Hz, supporting low-impedance operation in power circuits.
• Ripple Current Capability — Low-frequency ripple current 128.52 mA at 120 Hz and high-frequency ripple current 252 mA at 1 kHz for effective AC handling in supply filtering.
• Leakage Current — Specified leakage current of 141 µA, suitable for stable long-term operation under rated conditions.
• High Endurance — Rated life of 5,000 hours at 105°C (with specified case size conditions), delivering long-term reliability in elevated temperature environments.
• Robust Temperature Range — Operating from −55°C to +105°C to support a wide range of operating environments.
• Package and Mounting — Radial lead (polar) can package, size φ10 × 20 mm, lead spacing 5.0 mm (±0.5 mm), supplied in bulk/no terminal forming or bag packing for through-hole assembly workflows.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low-impedance construction and specified ripple current ratings make it suitable for bulk filtering and smoothing in switching regulators.
• General-Purpose Power Filtering — 100 V rating and 47 µF capacitance are useful for higher-voltage power-rail decoupling and energy storage in general electronics.
• Through-Hole PCB Assemblies — Radial lead format with 5.0 mm lead spacing is convenient for prototyping, repairs, and legacy board designs requiring through-hole components.

Unique Advantages

• Long High-Temperature Endurance — 5,000-hour load life at 105°C provides predictable performance and longevity in thermally demanding applications.
• Compact High-Voltage Capability — 100 V rating in a φ10 × 20 mm can enables higher-voltage designs without a large footprint.
• Designed for Switching Environments — Low impedance and measured tanδ support efficient filtering in switching power topologies.
• Clear Through-Hole Integration — Standard radial-lead spacing (5.0 mm) and bag/bulk packing simplify procurement and assembly for through-hole manufacturing.
• Regulatory Compliance — RoHS compliance meets common environmental requirements for modern electronics manufacturing.
