UWF0J221MCL1GS

The UWF0J221MCL1GS is a Nichicon aluminum electrolytic, chip-type capacitor engineered for surface-mount use on high-density PC boards. It delivers low impedance performance in a compact radial can SMD package and is tailored for automated assembly with carrier-tape feeding.

Key electrical and reliability characteristics include 220 µF capacitance at 6.3 V, an operating temperature range from −55 °C to +105 °C, AEC-Q200 compliance and RoHS conformity. Note: this product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Capacitance and Voltage — 220 µF rated capacitance at 6.3 V provides bulk energy storage in a compact SMD package.
• Low Impedance Performance — Specified impedance of 800 mΩ supports stable performance in decoupling and smoothing applications where low ESR is required.
• Extended Temperature Range — Operates from −55 °C to +105 °C, with endurance specified as 1000 hours at 105 °C.
• Ripple Current Ratings — Defined ripple capability of 75 mA at 120 Hz and 150 mA at 10 kHz for reliable filtering under AC stress.
• Automotive-Grade Reliability — AEC-Q200 compliant, aligning the part with industry reliability expectations for automotive electronics.
• Surface-Mount, Carrier-Tape Compatible — Chip-type radial can SMD designed for placement on high-density PCBs and applicable to automatic mounting machines fed with carrier tape.
• Mechanical and Mounting — Compact size L: 6.2 × D: 8 mm with a recommended land pattern of 8.3 × 8.3 mm for PCB footprint planning.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — Designed for electronic subsystems where AEC-Q200 reliability is required and compact SMD packaging is preferred.
• High-density SMD boards — Suited to board-level bulk storage and power smoothing on tightly packed assemblies where chip-type electrolytics are needed.
• Automated assembly lines — Carrier-tape compatible for efficient placement by automatic mounting machines.

Unique Advantages

• Compact energy storage: 220 µF in a 6.2 × 8 mm footprint provides significant capacitance for space-constrained designs.
• High-temperature endurance: Rated for operation up to +105 °C with 1000 hours endurance at that temperature for predictable life under thermal stress.
• Defined ripple capability: Specified ripple currents at both low and high frequency (75 mA at 120 Hz; 150 mA at 10 kHz) enable confident selection for filtering duties.
• Automotive-grade qualification: AEC-Q200 compliance supports deployment in applications requiring documented component reliability.
• Assembly-ready SMD format: Chip-type radial can design and carrier-tape compatibility streamline automated production and placement on high-density PCBs.
• Regulatory conformity: RoHS compliance simplifies reuse in regulated product lines.

Why Choose UWF0J221MCL1GS?

The UWF0J221MCL1GS balances compact SMD packaging with robust electrical and thermal performance, making it a suitable choice for engineers needing a low-impedance electrolytic capacitor for demanding environments. Its AEC-Q200 compliance and defined endurance at +105 °C provide predictable behavior in applications that require documented reliability.

This part is well suited for teams designing automotive electronics or any high-density assemblies that require automated placement and carrier-tape compatibility. Given its scheduled discontinuation status, it is most appropriate for existing designs and repair/repair-spare use rather than new product introductions.
