The UPW1J4R7MDD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPW series. It provides 4.7 µF capacitance at a 63 V rating in a compact φ5 × 11 mm can, engineered for miniature, low-impedance power applications.

Designed with a wide operating temperature range (−55 °C to 105 °C) and AEC‑Q200 qualification, this part targets switching power supplies and automotive electronic modules that require compact, reliable energy storage and ripple handling in through-hole assemblies.

Key Features

• Capacitance and Voltage: 4.7 µF nominal capacitance with a 63 V rated voltage and tolerance of −20% to +20% for predictable charge storage in power circuits.
• Low loss (tan δ): tanδ 0.09 (measured at 20 °C, 120 Hz), indicating low dielectric loss for improved performance in ripple and filtering applications.
• Ripple current capability: Low-frequency ripple current 20.4 mA at 120 Hz and high-frequency ripple current 68 mA at 10 kHz, supporting dynamic power conditions in supply circuits.
• Leakage current: Typical leakage current of 8.883 µA, suitable for circuits where low quiescent leakage is required.
• Temperature and endurance: Rated for −55 °C to 105 °C operation with a specified life/endurance of 2000 hours at 105 °C.
• Package and mounting: Radial lead, polarized can (φ5 × 11 mm) with 2.0 mm lead spacing (±0.5 mm) for straightforward through-hole mounting.
• Automotive-grade qualification: AEC‑Q200 rated, supporting use in automotive electronic systems that require component-level reliability validation.
• Packaging status: Available in bulk (no terminal forming) and bag packing; current part status: End Of Life.

Typical Applications

• Switching power supplies: Used for output filtering and decoupling where compact, low-loss capacitance helps control ripple and stabilize regulators.
• Automotive electronic modules: Suited for automotive systems that leverage AEC‑Q200‑rated components for enhanced reliability across temperature extremes.
• Through-hole power assemblies: Compact radial can form factor and standard lead spacing simplify integration into PCB layouts for power management tasks.

Unique Advantages

• Compact footprint: φ5 × 11 mm can (1.1 × 0.5 cm) provides significant capacitance in a small, space-saving package for dense power boards.
• Measured low dielectric loss: tanδ of 0.09 at 20 °C, 120 Hz, offering predictable performance under AC ripple conditions.
• High-temperature endurance: Rated for 2000 hours at 105 °C, enabling reliable operation in thermally demanding environments.
• Automotive-capable: AEC‑Q200 rating supports deployment in vehicle electronics where component qualification matters.
• Clear mounting format: Radial lead construction and 2.0 mm lead spacing simplify through-hole assembly and mechanical retention.
• Low leakage: Sub-10 µA leakage current characteristic helps maintain circuit efficiency and reduces standby losses.
