UPW1J122MHD

The UPW1J122MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPW series, optimized for low impedance and long-term reliability. It provides 1.2 mF capacitance at a 63 V rating in a compact φ18 × 30.5 mm can, designed for power filtering and energy-smoothing duties in compact power electronics.

Targeted use cases include switching power supplies and power-management subsystems where ripple handling, temperature endurance, and a small footprint are required. The part combines high ripple capability and an 8,000-hour endurance at 105°C to support robust designs over extended operating life.

Key Features

• Electrical Performance — 1.2 mF capacitance with ±20% tolerance and a rated voltage of 63 V, providing bulk energy storage and smoothing for DC rail regulation.
• Low Impedance — Specified impedance of 64 mΩ to support low-loss power delivery and reduced voltage ripple in switching applications.
• High Ripple Capability — Low-frequency ripple current of 2.507 A (120 Hz) and high-frequency ripple current of 2.95 A (10 kHz), enabling effective handling of switching and rectified ripple across frequency ranges.
• Wide Temperature Range — Operates from −55°C to +105°C, suitable for environments with extended temperature variation.
• Long Endurance — Rated life of 8,000 hours at 105°C, supporting long-term stability in elevated-temperature applications.
• Form Factor and Mounting — Radial lead, polarized can (φ18 × 30.5 mm) with 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Loss Characteristics — tan δ = 0.09 (measured at 20°C, 120 Hz), reflecting predictable dissipation for thermal and stability calculations.
• AEC-Q200 Qualified — Rated to AEC-Q200, aligning the part for automotive-grade reliability expectations where that qualification is required.

Typical Applications

• Switching Power Supplies — Bulk and output filtering to reduce voltage ripple and stabilize DC rails in compact SMPS designs.
• Automotive Electronics — Power smoothing and energy buffering in control modules and on-board power systems where AEC-Q200 qualification is required.
• DC–DC Converters — Input/output decoupling and transient energy delivery for converters in industrial and embedded systems.
• Power Management Modules — Energy storage and ripple suppression in power distribution and supervisory circuits.

Unique Advantages

• High Ripple Handling Across Frequencies: Elevated ripple current ratings at both 120 Hz and 10 kHz allow the capacitor to address both low-frequency rectified ripple and high-frequency switching noise.
• Compact, High-Capacity Package: 1.2 mF in a φ18 × 30.5 mm can delivers significant capacitance in a small through-hole footprint to save board space while meeting bulk storage needs.
• Extended High-Temperature Life: 8,000-hour endurance at 105°C supports longevity in thermally demanding environments, reducing the need for frequent replacements.
• Predictable Loss and Impedance: Specified tan δ and low impedance values make thermal and ripple loss budgeting straightforward during design.
• Automotive-Grade Reliability: AEC-Q200 rating addresses qualifications required for automotive and similarly demanding applications.
• Flexible Packaging: Available in bulk (no terminal forming) or bag packing to fit a range of assembly and inventory workflows.
