UPW1E222MHD3

The UPW1E222MHD3 is a radial-lead aluminum electrolytic capacitor with 2.2 mF capacitance rated at 25 V. It is a miniature, low-impedance, polarized can-style capacitor designed for board-level power filtering and energy buffering in systems that require sustained ripple handling and extended high-temperature endurance.

Key use cases include switching power supplies and automotive electronic modules where broad temperature range operation and long life are required. The part combines high ripple-current capability, compact dimensions (φ12.5 × 35.5 mm), and a 7000-hour endurance rating at 105°C.

Key Features

• Capacitance & Voltage — 2200 µF (2.2 mF) rated at 25 V with a tolerance of -20% to +20% for predictable bulk energy storage.
• Low Impedance — Impedance specified at 44 mΩ, supporting reduced voltage ripple in high-current applications.
• High Ripple Current Handling — Low-frequency ripple current 2.134 A (120 Hz) and high-frequency ripple current 2.51 A (10 kHz) to support switching regulators and power stages.
• Thermal & Endurance — Operating temperature range from -55°C to +105°C and a rated life of 7000 hours at 105°C under specified conditions.
• Loss Characteristics — tanδ of 0.16 (measured at 20°C, 120 Hz) for this capacitance and voltage combination.
• Leakage Current — Specified leakage current of 1650 µA (after 1 minute at 20°C), enabling designers to account for standby and bias currents.
• Mechanical & Mounting — Radial lead can package with φ12.5 × 35.5 mm size and 5 mm lead spacing (±0.5 mm tolerance) for through-hole mounting and reliable board placement.
• Packaging & Production — Available in bulk (no terminal forming) or bag packing; part is in mass production.
• Reliability Rating — AEC-Q200 listed in the product specifications for designs requiring that qualification.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing where 2.2 mF at 25 V and multi-amp ripple handling reduce output ripple and improve regulator stability.
• Automotive Electronic Modules — Power decoupling and energy buffering in automotive systems leveraging the AEC-Q200 rating and wide -55°C to +105°C operating range.
• Industrial Power Electronics — Board-level bulk capacitance for motor drives, converters, and control electronics requiring extended high-temperature endurance.

Unique Advantages

• High ripple capability: 2.134 A at 120 Hz and 2.51 A at 10 kHz support demanding switching environments without excessive heating.
• Compact, low-impedance design: 44 mΩ impedance in a φ12.5 × 35.5 mm can minimizes series voltage drop and helps maintain tight voltage regulation.
• Extended high-temperature life: 7000 hours at 105°C provides predictable longevity for designs exposed to elevated operating temperatures.
• Automotive-grade qualification: Inclusion of AEC-Q200 in the specifications supports use in vehicle electronics and other robust applications.
• Clear mechanical footprint: Radial-lead package with 5 mm lead spacing (±0.5 mm) simplifies through-hole layout and assembly planning.
• Production-ready packaging: Bulk and bag packing options and mass-production status ease procurement and volume assembly.
