UPW1J121MPD

The UPW1J121MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPW series. It is a radial lead, polarized capacitor optimized for power electronics with a 120 µF capacitance at 63 V rating.

Designed for switching power supplies and automotive electronics, this part delivers long-term endurance and measurable ripple-handling capability in a compact φ10 × 16 mm can, making it suitable for space-constrained through-hole power designs.

Key Features

• Capacitance & Voltage — 120 µF capacitance rated at 63 V for bulk decoupling and energy storage in power rails.
• Low dissipation (tan δ) — tanδ = 0.09 measured at 20 °C, 120 Hz, supporting efficient AC performance with reduced dielectric losses.
• Low impedance — Impedance of 388 mΩ, contributing to improved ripple suppression and stable performance under load.
• Ripple current capability — Low-frequency ripple current 390 mA (120 Hz) and high-frequency ripple current 600 mA (10 kHz), enabling effective smoothing across common switching frequencies.
• Leakage current — Specified leakage current of 226.8 µA, providing predictable standby and bias current characteristics.
• High-temperature endurance — Rated for 5,000 hours at 105 °C, delivering extended operational life for demanding environments.
• Wide operating temperature — –55 °C to 105 °C for use across a broad range of ambient conditions.
• Package and mounting — Radial lead can, size φ10 × 16 L, lead spacing 5 mm with 0.5 mm tolerance; available as bulk (no terminal forming) or bag packing.
• AEC-Q200 rating — Specified rating indicating qualification for automotive-grade applications.

Typical Applications

• Switching power supplies — Bulk energy storage and output filtering where compact size and low impedance improve transient response.
• Automotive electronics — Power rail smoothing and decoupling in electronic control units and in-vehicle power systems, supported by the AEC-Q200 rating and 105 °C endurance.
• DC–DC converters — Input/output filtering where specified ripple current ratings and low tanδ help maintain stable regulation under switching loads.
• Embedded power subsystems — Local decoupling for microcontroller and power-management boards in constrained through-hole layouts.

Unique Advantages

• Measurable, application-ready electricals — Clear specifications for capacitance, impedance (388 mΩ), tanδ (0.09), leakage (226.8 µA) and ripple currents make design calculations straightforward.
• Long endurance at elevated temperature — 5,000 hours at 105 °C supports designs requiring prolonged high-temperature operation.
• Compact radial can — φ10 × 16 mm footprint with 5 mm lead spacing provides a small, robust through-hole solution for power circuits.
• High-frequency ripple handling — 600 mA ripple current rating at 10 kHz helps address switching noise at higher frequencies.
• Automotive-grade qualification — AEC-Q200 rating supports deployment in automotive electronic assemblies where that qualification is required.
• Supply chain options — Available packaged in bulk (no terminal forming) or bag packing to suit different assembly workflows.
