UPJ1E470MED

The UPJ1E470MED is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, offering a 47 µF capacitance at a 25 V rating. It is part of a low-impedance family designed for power applications and is intended for general-purpose electronic circuits, including switching power supplies.

Key value propositions include compact radial can packaging (φ6.3 × 11 mm), defined ripple-current capability across low and high frequencies, and a wide operating temperature range from −55°C to 105°C for reliable performance in through-hole power designs.

Key Features

• Electrical Specification: 47 µF nominal capacitance with a rated voltage of 25 V and tolerance of ±20%, suitable for common decoupling and smoothing tasks.
• Low Loss / Impedance: Specified tan δ of 0.14 at 20°C and 120 Hz, supporting stable AC behavior in power circuits.
• Ripple Current Capability: Rated low-frequency ripple current of 63.75 mA at 120 Hz and high-frequency ripple current of 125 mA at 200 kHz to handle switching and ripple conditions.
• Leakage Current: Specified leakage current of 35.25 µA after voltage application, enabling predictable bias drain in designs.
• Reliability / Endurance: Rated for 2000 hours life at 105°C, providing defined endurance for demanding thermal environments.
• Package & Mounting: Radial lead, polarized aluminum can with lead spacing of 2.5 mm and compact dimensions (φ6.3 × 11 mm / L: 1.1 cm × D: 0.63 cm).
• Temperature Range: Operating from −55°C to 105°C to support a wide set of ambient conditions.
• RoHS Compliance: RoHS compliant per product data.
• Packing: Supplied in bulk/bag packing (no terminal forming).

Typical Applications

• Switching Power Supplies: Low-impedance behavior and rated ripple current make the UPJ1E470MED suitable for output filtering and bulk decoupling in switching regulators.
• General-Purpose Power Filtering: Useful for smoothing and decoupling in consumer and industrial electronic circuits that require a 47 µF, 25 V polarized capacitor.
• Through-Hole Power Boards: Compact radial can and 2.5 mm lead spacing simplify layout for legacy or mixed-technology PCBs that use through-hole components.

Unique Advantages

• Optimized for switching environments: UPJ series low-impedance characteristics are targeted at switching power supply applications, enabling effective ripple suppression.
• Defined ripple handling across frequencies: Published ripple current ratings at 120 Hz and 200 kHz let designers size capacitors for both mains-frequency and high-frequency switching noise.
• Predictable leakage and loss: Specified leakage current (35.25 µA) and tan δ (0.14 at 120 Hz) provide measurable parameters for power-budget and thermal calculations.
• Compact radial can footprint: φ6.3 × 11 mm size with 2.5 mm lead spacing enables space-efficient through-hole placement on power boards.
• Wide operating temperature: −55°C to 105°C rating supports a broad range of ambient conditions for industrial and consumer applications.
• RoHS compliant from a recognized manufacturer: Nichicon production and RoHS status support regulatory requirements for many product lines.
