UPJ1K4R7MDD

The UPJ1K4R7MDD is a miniature, radial‑lead aluminum electrolytic capacitor in Nichicon’s UPJ series, designed for low impedance and reliable operation in compact power applications. It is a polarized, 4.7 µF, 80 V device available in a φ5 × 11 mm can with 2 mm lead spacing.

This part targets general‑purpose electronics and power supply applications—benefiting designers who need a compact capacitor with defined ripple handling, low dissipation factor, and wide operating temperature range. Note: this part is currently listed as End Of Life.

Key Features

• Capacitance & Voltage — 4.7 µF rated capacitance with an 80 V rated voltage and capacitance tolerance of −20% to +20%.
• Low Dissipation — tanδ (DF) of 0.08 when measured at 20°C and 120 Hz (rated voltage 80 V), supporting efficient AC performance.
• Ripple Current Capability — Low‑frequency ripple current of 13 mA at 120 Hz and high‑frequency ripple current of 26 mA at 200 kHz to address both bulk and switching noise conditions.
• Leakage Current — Specified leakage current of 11.28 µA for predictable bias behavior in DC circuits.
• Temperature & Endurance — Operating temperature range from −55°C to +105°C with a specified endurance of 2000 hours.
• Compact Radial Package — Small form factor: φ5 × 11 mm (L: 1.1 cm × D: 0.5 cm) with 2 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• Polarized Radial Lead — Through‑hole radial lead mounting for straightforward PCB assembly in traditional power designs.

Typical Applications

• Switching Power Supplies — Low impedance characteristics and defined ripple current ratings help stabilize supply rails and smooth switching noise.
• General Purpose Power Decoupling — Compact capacitance solution for local decoupling in small form‑factor modules and power islands.
• Compact Electronics — Small φ5 × 11 mm can and radial lead form make it suitable for space‑constrained consumer and industrial boards requiring polarized electrolytic capacitance.

Unique Advantages

• Size‑efficient energy storage: 4.7 µF in a φ5 × 11 mm can delivers capacitance in a compact radial package for space‑limited designs.
• Defined AC performance: Measured tanδ of 0.08 (20°C, 120 Hz) provides predictable loss behavior for power conversion circuits.
• Dual‑band ripple handling: Listed ripple currents at 120 Hz and 200 kHz support both low‑frequency smoothing and high‑frequency switching environments.
• Wide temperature capability: −55°C to +105°C operation covers a broad range of environmental conditions for general‑purpose electronics.
• Straightforward PCB mounting: Polarized radial leads with 2 mm spacing simplify through‑hole assembly and mechanical retention.
