UPW2A180MED

The UPW2A180MED from Nichicon is a miniature aluminum electrolytic capacitor in the UPW series, designed for low-impedance, high-reliability board-level power applications. It is a radial-lead, polarized can-type capacitor specified for use in switching power supplies and automotive electronics, with an AEC-Q200 rating for applications requiring automotive-grade reliability.

Key Features

• Rated Voltage: 100 V rated voltage suitable for higher-voltage rail decoupling and smoothing.
• Capacitance & Tolerance: 18 µF capacitance with ±20% tolerance at 120 Hz, 20°C for predictable filtering performance.
• Miniature Radial Package: Radial can package with 2.5 mm lead spacing and compact dimensions (L: 1.5 × D: 0.63 cm) for space-constrained PCB layouts.
• Polarized Design: Polarized aluminum electrolytic construction for power filtering and bulk energy storage in DC circuits.
• Temperature Range: Rated for –55°C to +105°C operation to support a wide range of environmental conditions.
• High‑Temperature Endurance: Specified lifetime of 2000 hours at 105°C to meet demanding thermal requirements.
• Ripple Current Capability: Frequency-specific ripple ratings provided — 60 mA at 120 Hz and 200 mA at 10 kHz — for reliable operation under AC ripple stress common in switching supplies.
• AEC-Q200 Qualification: AEC-Q200 rating for automotive reliability requirements and applications.

Typical Applications

• Switching Power Supplies: Low-impedance miniature capacitor for output smoothing, decoupling and ripple attenuation in switching converters.
• Automotive Electronics: AEC-Q200 qualification and broad temperature range make it suitable for automotive power circuits and electronics modules.
• Space-Constrained Power Boards: Compact radial can and short lead spacing allow use where board area is limited and high-voltage filtering is required.

Unique Advantages

• High-voltage capability: 100 V rating supports higher-voltage rails without additional series components.
• Compact footprint: Small L × D dimensions combined with radial lead mounting simplify placement in dense assemblies.
• Automotive-grade reliability: AEC-Q200 rating aligns the component with automotive qualification expectations.
• Wide operating temperature: –55°C to +105°C range supports harsh environmental and thermal conditions.
• Designed for switching environments: Low-impedance UPW series construction and specified ripple current figures address the needs of switching power circuits.
• Long high-temperature endurance: 2000 hours at 105°C provides a defined lifecycle for thermal-stressed designs.
