UPJ1H181MPD

The UPJ1H181MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a radial-lead, polarized capacitor rated at 180 µF and 50 V, designed for applications that require low impedance and robust ripple handling.

Engineered for switching power supplies and general-purpose power filtering, the part delivers long load life at elevated temperatures and compact dimensions to fit space-constrained designs.

Key Features

• Capacitance & Voltage: 180 µF nominal capacitance with a rated voltage of 50 V and ±20% tolerance for predictable energy storage and decoupling.
• Low Loss (tan δ): tanδ = 0.10 measured at 20°C, 120 Hz, indicating controlled dissipation for stable performance in power applications.
• High Ripple Capability: Rated low-frequency ripple current 342.9 mA (120 Hz) and high-frequency ripple current 635 mA (200 kHz) to support power rail smoothing and switching supply loads.
• Leakage Current: Specified leakage current of 270 µA to help maintain predictable bias and minimize standby losses.
• Long Endurance: Load life of 5000 hours at 105°C (φ10 case) for extended reliability under elevated temperature and DC bias.
• Compact Radial Package: φ10×20L size (D: 1 cm × L: 2 cm) with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assemblies.
• RoHS Compliant: Meets RoHS requirements for lead-free manufacturing and regulatory compliance.
• Packaging Options: Available in bulk (no terminal forming) and bag packing to suit production and prototyping workflows.

Typical Applications

• Switching Power Supplies: Low impedance and rated ripple current make this capacitor suitable for output smoothing and energy buffering in SMPS circuits.
• DC–DC Converters: Provides bulk capacitance and transient support on converter output rails to stabilize voltage during load changes.
• Power Filtering and Decoupling: Compact radial form factor is useful for general-purpose filtering on power rails in industrial and consumer electronics.

Unique Advantages

• Low Impedance Design: Reduces voltage ripple and improves power integrity when used on switching regulator outputs.
• High Ripple Endurance: Dual-specified ripple current (120 Hz and 200 kHz) addresses both mains-frequency and high-frequency switching environments.
• Extended High‑Temperature Life: 5000-hour rating at 105°C (for φ10 case) supports longer service life in thermally demanding applications.
• Space‑Efficient Footprint: φ10×20L dimensions (1 cm × 2 cm) deliver 180 µF capacitance in a compact through-hole package for constrained PCBs.
• Through‑Hole Robustness: Radial lead form with 5 mm lead spacing simplifies placement and mechanical retention in board-level assemblies.
• Regulatory Compliance: RoHS compliance supports use in lead‑free manufacturing environments.
