The UUJ2A221MNJ6MS is a chip-type aluminum electrolytic capacitor from Nichicon's UUJ series, offering a high capacitance 220 μF value in a surface-mount, can-style package. It is designed for high-density PCBs and automatic placement using carrier tape, targeting applications that require high-voltage bulk capacitance with long-term stability.

This part is rated 100 V, polarized, RoHS compliant, and AEC-Q200 qualified, with an operating temperature range of −55 °C to 105 °C and an endurance of 5000 hours at 105 °C—features that support demanding electronic designs.

Key Features

• Electrical — 220 μF capacitance at a 100 V rated voltage with ±20% tolerance; polarized for DC bulk and smoothing functions.
• Package & Mounting — Chip-type radial can in an SMD package designed for surface mounting on high-density PC boards and compatible with automatic mounting machines fed by carrier tape.
• Temperature Range — Specified for −55 °C to +105 °C (applicable to the 10–100 V range), supporting wide-temperature operation.
• Reliability & Lifetime — AEC-Q200 qualified and rated for 5000 hours at 105 °C, with endurance characteristics specified after recovery to 20 °C.
• Ripple Performance — Low-frequency ripple current: 440 mA at 120 Hz; high-frequency ripple current: 660 mA at 10 kHz, suitable for smoothing and decoupling in power circuits.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulatory requirements for restricted substances.
• Mechanical Dimensions — Component size L: 2.15 × D: 1.6 cm with recommended surface-mount land size L: 1.63 × W: 1.63 cm for PCB layout reference.

Typical Applications

• Automotive electronics — Suited for automotive designs that require AEC-Q200 qualification combined with high capacitance and wide temperature capability.
• Power supply filtering — Provides bulk capacitance and smoothing for DC rails in designs requiring 100 V ratings and substantial ripple handling.
• High-density PCB assemblies — Chip-type SMD can package and carrier-tape compatibility enable automated placement on compact, densely populated boards.
• Long-life systems — Endurance of 5000 hours at 105 °C supports applications where extended high-temperature reliability is required.

Unique Advantages

• High-capacitance SMD form factor — Delivers 220 μF in a chip-style can for designs that need large capacitance without through-hole components.
• Automated assembly ready — Compatible with carrier-tape fed automatic mounting machines, reducing manual placement and assembly time.
• AEC-Q200 qualification — Provides a documented level of component qualification appropriate for demanding electronic environments.
• Wide operating temperature — −55 °C to 105 °C rating aligns with designs operating across broad thermal ranges.
• Defined ripple handling — Specified ripple current values at 120 Hz and 10 kHz help engineers size capacitors for power conditioning and decoupling tasks.
• Regulatory compliance — RoHS compliance supports deployment in regions and products with restricted substance requirements.
