UWG1E221MNL1GS

The UWG1E221MNL1GS is a chip‑type aluminum electrolytic capacitor engineered for surface mounting on high‑density printed circuit boards. It features a low‑impedance design and is suitable for automated assembly fed from carrier tape.

Designed to operate across a wide temperature range of −55°C to +105°C and AEC‑Q200 qualified, this capacitor targets automotive and other demanding environments that require stable capacitance, defined ripple handling, and long‑term endurance.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 25 V for bulk decoupling and energy storage in compact SMD implementations.
• Low Impedance — Specified impedance of 150 mΩ to support lower AC voltage drop and improved ripple performance in power applications.
• Ripple Current Ratings — Rated ripple current of 335 mA at 120 Hz and 670 mA at 10 kHz to address both low‑ and high‑frequency ripple conditions.
• Wide Temperature Range — Operates from −55°C to +105°C, maintaining performance across extreme ambient conditions.
• Automotive Qualification & Reliability — AEC‑Q200 qualified with a rated lifetime of 1000 hours at 105°C, supporting long‑term reliability requirements.
• Surface‑Mount, Automated Assembly — Chip type, radial can SMD package designed for high‑density PCBs and compatibility with automatic mounting machines fed by carrier tape.
• Tolerance & Polarization — Capacitance tolerance ±20% (−20% to +20%) and polarized construction for correct orientation in DC circuits.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• Automotive electronic modules — Power filtering and bulk decoupling on vehicle control and infotainment PCBs where AEC‑Q200 qualification and −55°C to +105°C operation are required.
• DC‑DC converters and power supplies — Energy storage and ripple suppression in compact, surface‑mount power stages thanks to low impedance and defined ripple current ratings.
• High‑density SMD circuit boards — Designed for surface mounting on tightly packed PCBs and compatible with automatic carrier‑tape assembly processes.

Unique Advantages

• Designed for automated assembly: Chip‑type SMD package and carrier‑tape compatibility simplify placement on high‑volume production lines.
• Reliable under temperature stress: Rated for −55°C to +105°C with 1000 hours endurance at 105°C, supporting designs that require stable long‑term performance.
• Automotive‑grade qualification: AEC‑Q200 qualification provides documented suitability for automotive applications where this level of qualification is required.
• Quantified ripple handling: Specified ripple currents at both 120 Hz and 10 kHz allow designers to match capacitor selection to expected operating conditions.
• Low impedance for tighter regulation: 150 mΩ impedance helps reduce AC voltage drop and improve power rail stability in compact layouts.
