UWD1H221MCL1GS

The UWD1H221MCL1GS is a chip-type aluminum electrolytic capacitor in the Nichicon UWD series, offering 220 µF capacitance at 50 V in a compact surface-mount can package. It is engineered for use on high-density PC boards and automatic placement processes, combining low impedance characteristics with high-temperature reflow compatibility.

Key value comes from its tolerance to elevated processing and operating temperatures (reflow up to 260°C and operating to +105°C), AEC-Q200 qualification, and a long endurance rating of 5000 hours at 105°C—attributes that address demanding assembly and reliability needs in automotive and industrial electronics.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 50 V, with capacitance tolerance of ±20% (120 Hz, 20°C).
• Low Impedance Performance — Specified impedance of 180 mΩ, supporting applications that require reduced ESR for power stability.
• High-Temperature Operation — Rated for operation from −55°C to +105°C, suitable for elevated-temperature environments.
• High-Temperature Reflow Compatibility — Designed to withstand 260°C peak reflow soldering (recommended 260°C peak for 5 seconds; 230°C over 60 seconds as specified), enabling use with lead-free assembly processes.
• Long Endurance — Qualified for 5000 hours at 105°C, with defined limits on capacitance change, tan δ and leakage current after endurance testing.
• Ripple Current Ratings — 335 mA at 120 Hz and 670 mA at 10 kHz, listed for frequency-dependent ripple handling.
• Surface-Mount Can Package — Chip (radial, can - SMD) construction optimized for automatic mounting machines and high-density PCB layouts; component dimension L: 1 × D: 1 cm with recommended land size L: 1.03 × W: 1.03 cm.
• Automotive-Grade Reliability — AEC-Q200 qualified and RoHS compliant, aligning with automotive reliability requirements and environmental directives.

Typical Applications

• Automotive electronic modules — Component suited for assembly and use in automotive electronic systems that require AEC-Q200 qualification and high-temperature endurance.
• High-density PCB assemblies — Designed for surface mounting on compact boards where space and automated placement are priorities.
• Automatic assembly lines — Package and carrier-tape compatibility support automatic mounting and high-throughput production.

Unique Advantages

• High-temperature reflow readiness: Rated for 260°C peak reflow conditions, enabling compatibility with modern lead-free solder processes.
• Extended high-temperature life: 5000 hours at 105°C endurance rating provides predictable long-term behavior in elevated-temperature applications.
• Automotive reliability: AEC-Q200 qualification supports deployment in applications subject to automotive reliability standards.
• Low impedance: 180 mΩ impedance helps reduce losses and improve power stability where lower ESR is required.
• Compact SMD can format: Small 1 × 1 cm footprint and defined land pattern simplify integration into dense board layouts and automated assembly flows.
