UWT1H221MNL1GS

The UWT1H221MNL1GS is a chip-type aluminum electrolytic capacitor offering 220 µF capacitance at a 50 V rating in a compact surface-mount radial can package. It is engineered for high-density PCB mounting and automated assembly, with specifications targeted at applications requiring wide temperature operation and robust endurance.

Key value propositions include a wide operating temperature range from −55°C to +105°C, AEC-Q200 qualification for automotive applications, and a 1000 hour rated lifetime at 105°C—providing predictable performance under elevated temperature stress.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Wide Temperature Range — Specified operating temperature from −55°C to +105°C for use across broad thermal environments.
• Automotive-Grade Qualification — AEC‑Q200 qualified, supporting use in automotive electronic applications where this qualification is required.
• Surface-Mount Chip Type — Designed for surface mounting on high-density PCBs in a radial, SMD can package and compatible with automatic mounting machines fed with carrier tape.
• High-Temperature Endurance — Rated for 1000 hours at 105°C with defined limits for capacitance change, tan δ, and leakage current after the endurance test.
• Ripple Current Performance — Specified ripple current capabilities of 220 mA at 120 Hz and 330 mA at 10 kHz for real-world filtering and decoupling conditions.
• Standards & Compliance — RoHS compliant to applicable directives.
• Compact Footprint — Small physical size (L: 1 cm × D: 1 cm) with recommended PCB land size of 1.03 cm × 1.03 cm for dense layouts.

Typical Applications

• Automotive Electronics — Suited for automotive subsystems that require AEC‑Q200 qualified capacitors with wide temperature capability and defined high-temperature lifetime.
• High-Density Surface-Mount Circuits — Intended for use on compact PCBs where chip-type SMD capacitors enable space-efficient power filtering and decoupling.
• Automated Assembly Lines — Designed for compatibility with automatic mounting machines using carrier tape to support high-volume production processes.

Unique Advantages

• Wide operating temperature window — −55°C to +105°C specification enables deployment across harsh thermal environments without design over‑specification.
• AEC‑Q200 qualification — Explicit qualification for automotive applications provides clarity for designs that require that level of component reliability verification.
• Defined high-temperature lifetime — 1000 hours at 105°C with endurance criteria helps engineers predict long-term behavior under sustained elevated temperatures.
• Practical ripple performance — Separate ripple current ratings at 120 Hz and 10 kHz give measurable targets for power-supply filtering design and simulation.
• Compact SMD can package — Small 1 cm × 1 cm footprint and standard land pattern support dense board layouts while maintaining through-process compatibility with automated placement.
• Regulatory compliance — RoHS compliance supports use in regulated production environments.
