UCB1V220MCL1GS

The UCB1V220MCL1GS is a chip-style aluminum electrolytic capacitor from Nichicon’s UCB series. It is a surface-mount, radial can (chip) capacitor engineered for demanding temperature environments and automated assembly.

Designed for automotive and other high-temperature applications, this part offers a rated capacitance of 22 µF at 35 V with long-life assurance and AEC-Q200 qualification for reliability in harsh conditions.

Key Features

• Dielectric & Capacitance — 22 µF capacitance with ±20% tolerance at 120 Hz, 20°C, suitable for decoupling and smoothing functions within its rated voltage.
• Voltage Rating — Rated voltage of 35 V, with the UCB series supporting a broad voltage range across the family.
• High‑temperature Endurance — Load life of 7000 hours at +105°C; after the endurance test the capacitance remains within ±30% of the initial value and leakage current stays at or below initial specification.
• Loss and Leakage Characteristics — Low leakage current specified as not more than 0.03 CV or 4 µA (whichever is greater) after 2 minutes at 20°C; tan δ (max.) for 35 V is 0.14, supporting stable AC behaviour.
• Ripple Current Performance — Rated ripple current of 42 mA at 120 Hz and 63 mA at 10 kHz for thermal and AC stress planning.
• Package & Mounting — Chip-type radial can for surface-mount assembly; dimensions L: 7 × D: 6.3 mm with recommended land size L: 6.6 × W: 6.6 mm, and compatible with carrier-tape automatic mounting.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), aligning with requirements for regulated environments.
• Soldering Robustness — Meets resistance-to-soldering-heat requirements (hot plate 250°C for 30 s) with capacitance change within ±10% and leakage/tan δ remaining within specified limits.

Typical Applications

• Automotive Electronics — For use in automotive electronic modules where AEC‑Q200 qualification and high‑temperature endurance (+105°C) are required.
• Surface‑mount Power Assemblies — Chip can package and carrier‑tape compatibility enable automated placement in compact SMD power and filtering circuits.
• High‑temperature Electronics — Suited for circuits operating in elevated ambient temperatures, benefitting from a 7000‑hour life rating at +105°C.

Unique Advantages

• Long life at elevated temperature: 7000 hours at +105°C ensures sustained capacitance and leakage performance in high‑temperature duty cycles.
• AEC‑Q200 qualification: Provides an assurance of component-level reliability for designs targeting regulated or rugged environments.
• Compact SMD chip can: Small L: 7 × D: 6.3 mm footprint with recommended land pattern for space‑constrained surface‑mount assemblies.
• Automated assembly ready: Compatible with carrier‑tape feeding for pick‑and‑place lines, simplifying high‑volume manufacturing.
• Controlled electrical losses and leakage: Specified tan δ (0.14 at 35 V) and leakage current limits aid predictable AC behaviour and low quiescent losses.
• Regulatory compliance: RoHS compliance supports use in regions and products with materials restrictions.

Why Choose UCB1V220MCL1GS?
