UUL1E221MNL1GS

The UUL1E221MNL1GS is a chip‑type aluminum electrolytic capacitor from the Nichicon UUL series designed for surface mounting on high‑density PC boards. It delivers 220 µF at 25 V in a compact radial, can‑style SMD package intended for demanding environments.

Key value comes from extended high‑temperature endurance and industry qualifications: a rated operating range of −40°C to +105°C, a load life of 5000 hours at +105°C, RoHS compliance, and AEC‑Q200 qualification for automotive applications.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance, suitable for bulk decoupling and power‑rail smoothing within that voltage range.
• Long‑Life, High‑Temperature Endurance — Load life specified at 5000 hours at +105°C; endurance performance includes capacitance change within ±30% after the test when restored to 20°C.
• Automotive Reliability — AEC‑Q200 qualified and RoHS compliant, supporting use in automotive electronics where qualification is required.
• Wide Operating Temperature — Rated for −40°C to +105°C to handle a broad range of thermal environments.
• Surface‑Mount, Compact Package — Chip type radial can SMD package sized L: 1 × D: 1 cm with recommended land size L: 1.03 × W: 1.03 cm, optimized for high‑density PCB layouts.
• Ripple Current Performance — Rated ripple current of 216 mA at 120 Hz and 324 mA at 10 kHz to support AC components on power rails.
• Leakage and Dissipation Characteristics — Specified leakage current after 2 minutes at 20°C not more than 0.01 CV or 3 µA (whichever is greater); tan δ limits provided per rated voltage.

Typical Applications

• Automotive power electronics — Bulk smoothing and decoupling on vehicle power rails where long life at elevated temperatures is required.
• Control modules and ECUs — Surface‑mount form factor and AEC‑Q200 qualification make it suitable for high‑density electronic control units.
• On‑board electronics in harsh environments — Use in modules that require stable capacitance and controlled leakage across −40°C to +105°C.

Unique Advantages

• Proven long‑life performance: 5000 hours at +105°C gives designers a measurable endurance baseline for high‑temperature applications.
• Automotive qualification: AEC‑Q200 status supports inclusion in automotive electronic designs that require established component qualifications.
• Compact SMD package: Radial, can‑style SMD package and small land pattern enable high‑density PCB layouts without sacrificing capacitance.
• Wide temperature tolerance: −40°C to +105°C operating range accommodates both cold‑start conditions and sustained elevated temperatures.
• Measured ripple handling: Specified ripple current values at 120 Hz and 10 kHz help ensure reliable performance under AC load conditions.
