UPW2E220MHD

The UPW2E220MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can, part of Nichicon's UPW series. It delivers 22 µF capacitance at a 250 V rating and is optimized for low-impedance applications such as switching power supplies and other power electronics.

Designed for demanding thermal and ripple environments, this polarized capacitor features a wide operating temperature range from −40°C to 105°C and long endurance of 7000 hours at 105°C, making it suitable for industrial and automotive system designs that require robust filtering and energy storage.

Key Features

• Electrical Performance — 22 µF nominal capacitance with ±20% tolerance and a rated voltage of 250 V suitable for high-voltage filtering and energy storage.
• Low Loss Characteristic — tanδ specified at 0.15 (measured at 20°C, 120 Hz) to help minimize dissipation in AC ripple conditions.
• Ripple Handling — Low-frequency ripple current 155 mA (120 Hz) and high-frequency ripple current 248 mA (10 kHz), providing defined ripple capability across common power-conversion frequencies.
• Leakage and Endurance — Leakage current rated at 320 μA and endurance specified at 7000 hours at 105°C for stable long-term performance under elevated temperature stress.
• Thermal Range — Operates from −40°C to 105°C to cover a wide range of environmental conditions.
• Package & Mounting — Radial lead, can-style package with body size φ12.5 × 25 mm and 5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• AEC Qualification — Rated for AEC-Q200, supporting usage in automotive-grade applications where AEC qualification is required.

Typical Applications

• Switching Power Supplies — Provides compact, low-impedance filtering and bulk storage for DC rails and output smoothing in switching regulators.
• Automotive Power Electronics — AEC-Q200 rating and 105°C endurance make it suitable for in-vehicle DC filtering and power modules that require long-term thermal reliability.
• Industrial Controllers — Used for decoupling and energy buffering in industrial control and power conversion equipment operating across wide temperatures.

Unique Advantages

• Clear ripple specifications: Defined ripple currents at both 120 Hz and 10 kHz (155 mA and 248 mA) let designers match capacitor selection to expected operating frequencies.
• High-temperature endurance: 7000 hours at 105°C provides predictable lifetime characteristics for designs exposed to elevated ambient temperatures.
• Compact radial package: φ12.5 × 25 mm can with 5 mm lead spacing offers a space-efficient solution for through-hole assemblies.
• AEC-Q200 rated: Qualification for automotive-grade requirements enables use in vehicle systems and other environments where AEC compliance is required.
• Measured leakage and loss data: Specified leakage current (320 μA) and tanδ (0.15 at 20°C, 120 Hz) support thermal and loss budgeting during design validation.
• Packaging flexibility: Available in bulk (no terminal forming) or bag packing to accommodate assembly and prototyping workflows.
