UPJ2A4R7MED

The UPJ2A4R7MED is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a polarized, radial-lead component designed for general-purpose power applications and is particularly suited for switching power supplies where low impedance and compact size are required.

Key electrical characteristics include 4.7 µF capacitance at a 100 V rating, a low dissipation factor (tanδ 0.08 at 20°C, 120 Hz), and operation across a −55°C to 105°C temperature range. The part is supplied in bulk or bag packing for through-hole assembly.

Key Features

• Electrical Rating: 4.7 µF capacitance with a 100 V rated voltage and tolerance ±20% (−20% to +20%), suitable for higher-voltage DC filtering and decoupling tasks.
• Low Loss / Low Impedance: Dissipation factor tanδ = 0.08 (measured at 20°C, 120 Hz), supporting efficient energy handling and reduced heat generation in power circuits.
• Ripple Current Capability: Defined ripple currents of 17 mA at 120 Hz (low frequency) and 34 mA at 200 kHz (high frequency) for handling AC ripple in switching and DC/DC converter outputs.
• Leakage Current: Specified leakage current of 14.1 µA, enabling predictable bias behavior in long-term DC applications.
• Reliability / Endurance: Rated life of 2000 hours at 105°C, providing measured endurance for elevated-temperature operation.
• Compact Radial Package: Miniature can: diameter φ6.3 mm × length 11 mm (size 0.63 × 1.1 cm), radial lead mounting with 2.5 mm lead spacing (±0.5 mm), for tight board layouts and through‑hole assembly.
• Environmentally Compliant: RoHS compliant construction.

Typical Applications

• Switching Power Supplies: Output smoothing and decoupling where low impedance and compact size help maintain regulation and reduce ripple.
• DC/DC Converters: Bulk and local filtering in higher-voltage converter stages using through-hole mounting.
• Industrial Power Electronics: General-purpose power filtering in control modules and instrumentation that operate across −55°C to 105°C.
• Embedded and Board-Level Power Rails: Decoupling and energy storage for discrete power rails requiring a 100 V rating in a small radial package.

Unique Advantages

• High Voltage Capability: 100 V rating enables use in higher-voltage rails and fewer series components compared with lower-voltage options.
• Compact Footprint: φ6.3 × 11 mm can size and 2.5 mm lead spacing make it easy to integrate into dense, through-hole board layouts.
• Measured Ripple Performance: Specified ripple currents at both low and high frequencies allow designers to evaluate thermal and AC performance against actual application conditions.
• Predictable Losses: Low dissipation factor (tanδ 0.08 at 120 Hz) supports thermal budgeting and efficiency planning in power subsystems.
• Wide Operating Range: −55°C to 105°C rating supports applications across industrial temperature environments.
• Proven Series Characteristics: UPJ series attributes such as low impedance and switching-supply suitability provide a clear design reference for power filtering tasks.
