UPJ1C181MED

The UPJ1C181MED is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series, configured in a radial-lead can. It provides 180 µF capacitance at a 16 V rating with polarized operation and is intended for general-purpose power applications.

Designed for low-impedance power filtering in compact board layouts, this part supports wide ambient operation from −55°C to +105°C and a rated life of 2000 hours at 105°C, offering dependable ripple handling and stability for power-supply designs.

Key Features

• Capacitance & Voltage: 180 µF at 16 V, with a capacitance tolerance of −20% to +20% for predictable decoupling and bulk energy storage.
• Low-loss behavior: Tangent of loss angle (tan δ) of 0.16 measured at 20°C, 120 Hz, supporting efficient filtering with controlled dissipation.
• Ripple current capability: Low-frequency ripple current 153.9 mA (120 Hz) and high-frequency ripple current 285 mA (200 kHz), enabling effective smoothing across a range of switching frequencies.
• Leakage current: Specified leakage current of 86.4 µA for predictable standby and bias conditions.
• Temperature and endurance: Operating range −55°C to +105°C with a rated endurance of 2000 hours at 105°C for sustained reliability under elevated temperatures.
• Compact radial package: Radial-lead can, size φ6.3 × 15L (L: 1.5 cm × D: 0.63 cm) with 2.5 mm lead spacing (±0.5 mm), suited to tight board footprints and through-hole assembly.
• RoHS compliant: Manufactured in compliance with RoHS requirements.

Typical Applications

• Switching power supplies: Low impedance and defined ripple-current capability make it suited to output and bulk filtering in switch-mode power supplies.
• Power-supply decoupling: Compact radial format and 180 µF capacitance support local decoupling on DC power rails in general-purpose electronic designs.
• Compact board-level power modules: Small φ6.3 × 15 mm can and tight lead spacing enable use where PCB area is limited and axial/drilled mounting is preferred.

Unique Advantages

• Space-efficient power filtering: Small-diameter radial can (φ6.3) provides 180 µF capacitance in a compact footprint for dense layouts.
• Broad temperature operation: −55°C to +105°C rating supports designs exposed to wide ambient or elevated operating temperatures.
• Predictable ripple performance: Specified ripple-current values at both low and high frequency help designers size capacitors for switching and high-frequency noise attenuation.
• Controlled dissipation: Measured tan δ at standard test conditions gives designers clear loss characteristics to manage thermal and efficiency budgets.
• Through-hole robustness: Radial-lead construction simplifies prototyping and through-hole assembly while providing reliable mechanical retention.
• Regulatory compliance: RoHS compliance supports environmentally constrained designs and procurement requirements.
