UPJ2E4R7MPD

The UPJ2E4R7MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPJ series. It is a radial-lead, polarized can-type capacitor designed for general-purpose use and is ideally suited for switching power supply applications.

Key value propositions include a low-impedance design, a compact φ10×16L package with 5 mm lead spacing, and high-temperature endurance rated for 5000 hours at 105°C, making it suitable for compact power filtering and energy-storage roles in electronics.

Key Features

• Capacitance and Voltage: 4.7 µF nominal capacitance with a rated voltage of 250 V and a capacitance tolerance of -20% to +20%.
• Low Impedance & Loss: Low-impedance UPJ series construction with a specified tanδ of 0.2 (measured at 20°C, 120 Hz) to support stable performance in power circuits.
• Ripple and Leakage: Low-frequency ripple current 60 mA at 120 Hz and high-frequency ripple current 96 mA at 200 kHz; leakage current specified at 147 µA.
• High-Temperature Endurance: Rated life/endurance of 5000 hours at 105°C (specified load-life conditions), designed for extended operation in elevated temperature environments.
• Package & Mounting: Radial lead, polarized can package; size φ10×16L with 5 mm lead spacing (lead spacing tolerance ±0.5 mm) for through-hole assemblies.
• Operating Range & Compliance: Operating temperature range -40°C to +105°C and RoHS-compliant construction.

Typical Applications

• Switching Power Supplies: Energy storage and output filtering where the UPJ series’ low impedance and high-temperature endurance improve ripple performance and reliability.
• General-Purpose Power Filtering: Decoupling and smoothing in compact power modules and supply rails for a variety of electronic equipment.
• Industrial Control Electronics: Power conditioning in control circuits that require sustained performance at elevated temperatures and under continuous load.
• Consumer Power Adapters and Chargers: Bulk and output filtering in small form-factor adapters where radial through-hole mounting and compact size are needed.

Unique Advantages

• Compact, through-hole form factor: φ10×16L can with 5 mm lead spacing offers space-efficient placement for designers working in constrained layouts.
• Designed for elevated-temperature operation: 5000-hour endurance at 105°C supports long-term reliability in thermally demanding power applications.
• Measured low-loss characteristics: Tanδ of 0.2 (20°C, 120 Hz) reduces dissipation in AC and ripple conditions, supporting stable voltage filtering.
• Targeted ripple handling: Specified ripple currents of 60 mA (120 Hz) and 96 mA (200 kHz) give clear design parameters for both low- and high-frequency filtering.
• Clear electrical limits: Leakage current specified at 147 µA and polarized construction provide predictable behavior for power supply designers.
• RoHS compliant: Meets RoHS directive requirements for lead-free assembly and regulatory compliance.
