UUL1E220MCL1GS

The UUL1E220MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UUL series, designed for surface mounting on high-density printed circuit boards. It delivers 22 µF at 25 V in a compact SMD can package and is optimized for long life and reliability in demanding environments.

Key value propositions include a rated operating range from –40°C to +105°C, a proven endurance of 5000 hours at +105°C under rated voltage, RoHS compliance, and AEC-Q200 qualification for applications requiring elevated reliability.

Key Features

• Capacitance and Voltage — 22 µF nominal capacitance with a 25 V rated voltage and polarization, suitable for decoupling and smoothing on power rails.
• Long-life, High-temperature Endurance — Rated for 5000 hours at +105°C with the specified voltage applied; capacitance change after endurance is within ±30% and leakage remains at or below initial specification.
• Temperature Range — Operates over a category temperature range of –40°C to +105°C, supporting designs exposed to wide thermal variation.
• Electrical Characteristics — Capacitance tolerance ±20% at 120 Hz, leakage current after 2 minutes ≤ 0.01 CV or 3 µA (whichever is greater), and tan δ (25 V) maximum 0.16 at 120 Hz, 20°C.
• Ripple Current Ratings — Specified ripple current of 42 mA at 120 Hz and 63 mA at 10 kHz, useful for selecting capacitors in AC/ripple-prone circuits.
• Surface-mount, Compact Package — Radial can SMD chip package designed for high-density PCBs with a nominal footprint recommendation of 6.6 × 6.6 mm.
• Standards and Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and automotive-grade applications.
• Soldering and Handling Robustness — Meets resistance to soldering heat test (30 s at 250°C hot plate) with capacitance change within ±10% and no increase in leakage beyond initial specification.

Typical Applications

• Automotive Electronics — Features AEC-Q200 qualification and 5000-hour high-temperature endurance at +105°C, making it suitable for control modules, sensors, and power circuitry in vehicles.
• Power Rail Decoupling — 22 µF at 25 V with defined ripple current ratings provides stable decoupling and smoothing on local power rails for microcontrollers and power converters.
• Industrial Control — Suited for industrial sensor conditioning and control boards that require long life and wide operating temperature range.
• Embedded and Communication Modules — Compact chip package and surface-mount mounting support high-density PCB layouts in communication and embedded systems.

Unique Advantages

• Long-term high-temperature stability: 5000-hour endurance at +105°C ensures predictable performance and extended service life in thermally demanding designs.
• Automotive-grade qualification: AEC-Q200 qualification provides an explicit reliability baseline for vehicle electronics and other high-reliability markets.
• Compact SMD can package: Chip-type radial can in an SMD form factor enables high-density placement while retaining the performance characteristics of aluminum electrolytics.
• Clear electrical specifications: Defined leakage current limits, tan δ, and ripple current ratings allow straightforward integration and margin calculation during design.
• RoHS compliance: Conforms to 2011/65/EU and (EU)2015/863 regulations for restricted substances.
