UPW1H222MHD

The UPW1H222MHD is a miniature aluminum electrolytic capacitor from Nichicon’s UPW series designed for switching power supplies and related power-electronic applications. It is a radial-lead, polarized can-type capacitor engineered for low impedance and long-term operation in demanding environments.

Key attributes include a capacitance of 2.2 mF rated at 50 V, low DC impedance, and AEC-Q200 qualification for applications requiring proven reliability and extended endurance at elevated temperatures.

Key Features

• Electrical Performance — 2.2 mF capacitance at 50 V with tolerance ±20%, delivering bulk energy storage suitable for power supply filtering and decoupling.
• Low Impedance — Specified impedance of 46 mOhm to support lower ripple voltage under load in switching power systems.
• Ripple Handling — Rated ripple current of 2.635 A at 120 Hz and 3.1 A at 10 kHz, enabling effective smoothing across a range of switching frequencies.
• High Temperature Endurance — Specified lifetime of 8000 hours at 105°C, supporting continuous operation in elevated-temperature environments.
• Wide Operating Temperature — Category temperature range from –55°C to +105°C for broader environmental tolerance.
• Package and Mounting — Radial lead, can-style package with 7.5 mm lead spacing and compact dimensions (L: 3.55 cm × D: 1.8 cm) for through-hole assemblies.
• Automotive-Grade Qualification — AEC-Q200 rating for applications that require component-level automotive qualification.

Typical Applications

• Switching Power Supplies — Bulk and output filtering to reduce ripple and stabilize DC rails in switched-mode power supplies.
• Automotive Electronics — Energy storage and decoupling in automotive systems where AEC-Q200 qualification and high temperature endurance are required.
• Through-Hole Power Assemblies — Radial-lead mounting for PCB-level power modules and industrial control boards that use through-hole components.

Unique Advantages

• Low impedance for cleaner rails: 46 mOhm impedance reduces voltage ripple under load, improving power stability for converters and regulators.
• Frequency-capable ripple performance: Ripple ratings at both 120 Hz and 10 kHz demonstrate suitability across low- and high-frequency switching environments.
• Extended high-temperature life: 8000 hours at 105°C provides a measurable endurance metric for designs expected to operate continuously at elevated temperatures.
• Automotive-capable qualification: AEC-Q200 rating supports use in designs that require automotive-level component qualification.
• Compact radial can: Small footprint (L: 3.55 cm × D: 1.8 cm) and 7.5 mm lead spacing simplify integration into through-hole power layouts.
