UPW1E182MHD

The UPW1E182MHD is a miniature, low-impedance aluminum electrolytic capacitor in a radial lead can designed for high-reliability power applications. It provides 1,800 µF capacitance at a 25 V rating with a compact φ12.5 × 30.5 mm package and 5 mm lead spacing.

Designed for demanding environments, this AEC-Q200 rated part delivers long endurance (7,000 hours at 105°C), robust ripple current capability, and a wide operating temperature range of −55°C to 105°C—making it suitable for power filtering and energy smoothing in electronic systems.

Key Features

• Capacitance & Voltage — 1,800 µF (±20%) at 25 V for bulk energy storage and smoothing.
• Low Impedance — Rated impedance of 50 mΩ to support low-loss filtering in high-current paths.
• High Ripple Current — 1.964 A at 120 Hz (low frequency) and 2.31 A at 10 kHz (high frequency) to handle switching and high-frequency ripple in power supplies.
• Loss Tangent — tan δ = 0.14 measured at 20°C, 120 Hz, enabling predictable dissipation characteristics.
• Leakage Current — 1,350 µA after rated-voltage application, supporting predictable standby and bias behavior.
• Durability & Temperature — Rated for −55°C to 105°C with an endurance of 7,000 hours at 105°C.
• Package & Mounting — Radial lead can (φ12.5 × 30.5 mm) with 5.0 mm lead spacing and 0.5 mm spacing tolerance for through-hole assemblies.
• Automotive-Grade Qualification — AEC-Q200 rated for applications requiring automotive-level reliability.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple current performance for input/output filtering and smoothing of switching converters.
• Automotive Electronics — AEC-Q200 qualification and wide temperature range enable use in control modules, power distribution, and in-vehicle power rails.
• DC–DC Converters — High capacitance and ripple capability support voltage stabilization and transient suppression in converter outputs.
• Backup & Hold-Up Circuits — Large 1,800 µF capacitance provides short-term energy storage for brownout protection and power hold-up functions.

Unique Advantages

• High energy density in a small can — 1,800 µF in a φ12.5 × 30.5 mm package reduces board area for power storage functions.
• Reliable, long-life performance — 7,000-hour endurance at 105°C supports sustained operation in elevated-temperature environments.
• Handles switching and HF ripple — Combined LF and HF ripple current ratings (1.964 A at 120 Hz; 2.31 A at 10 kHz) address both mains-frequency and high-frequency switching noise.
• Automotive-level qualification — AEC-Q200 rating provides documented reliability for vehicle electronics and other demanding systems.
• Predictable electrical behavior — Specified tan δ and leakage current enable designers to model dissipation and bias behavior accurately.
• Flexible procurement — Bulk and bag packing options support both prototype builds and higher-volume production runs.
