URZ1E222MHD

The URZ1E222MHD from Nichicon is a radial-lead, miniature aluminum electrolytic capacitor in the URZ series designed for general-purpose power applications. It delivers 2.2 mF (2200 µF) capacitance at 25 V in a compact φ18 × 15 mm can, offering a combination of high capacitance and a wide operating temperature range for demanding embedded and industrial electronics.

Engineered for reliable smoothing, decoupling and energy-storage roles, this component targets power supply rails, control electronics and compact assemblies where board space and robust thermal endurance (−55°C to +105°C) are required.

Key Features

• Electrical Performance — 2200 µF capacitance at 25 V with tolerance −20% to +20%, suitable for bulk decoupling and energy storage on low-voltage rails.
• Loss Characteristics — Specified tanδ (DF) of 0.18 measured at 20°C, 120 Hz, enabling predictable AC behavior for filtering and smoothing applications.
• Ripple Current Capability — Low-frequency ripple current 970 mA (120 Hz) and high-frequency ripple current 1,115.5 mA (100 kHz), supporting applications with varying ripple spectra.
• Leakage Current — Specified leakage current of 1,650 µA, allowing designers to budget standby loss and bias characteristics accurately.
• Thermal & Reliability — Rated for operation from −55°C to +105°C with a life/endurance rating of 1,000 hours at 105°C, providing predictable life performance in elevated-temperature environments.
• Mechanical & Mounting — Radial lead, φ18 × 15 mm can with 7.5 mm lead spacing (±0.5 mm), shipped in bulk or bag packing (no terminal forming) for easy manual or wave-through-hole assembly.

Typical Applications

• Power Supply Smoothing — Bulk decoupling on 25 V rails where compact energy storage and predictable ripple handling are required.
• Embedded Control Electronics — Local energy reservoir and filtering in microcontroller-based and industrial control boards operating across a wide temperature range.
• Motor Drive & Power Control — Support for low-voltage drive circuits and ancillary power stages that require stable capacitance under ripple load and elevated temperatures.

Unique Advantages

• High Capacitance in a Small Package: 2200 µF in a φ18 × 15 mm can lets you retain bulk capacitance while minimizing board area.
• Wide Temperature Range: −55°C to +105°C rating enables deployment across harsh ambient and industrial environments without derating the component selection.
• Defined Endurance: 1,000 hours at 105°C provides a clear reliability target for thermal-stress and lifetime planning.
• Frequency-Resilient Ripple Handling: Separate low-frequency (970 mA at 120 Hz) and high-frequency (1,115.5 mA at 100 kHz) ripple specifications allow precise thermal and ripple-loss budgeting across application spectra.
• Standardized Mounting: Radial lead and 7.5 mm lead spacing simplify through-hole placement and mechanical retention in compact assemblies.
