UCW1V220MCL1GS

The UCW1V220MCL1GS from Nichicon is a chip-type aluminum electrolytic capacitor in the UCW series designed for surface-mount assembly. It delivers 22 µF capacitance at a 35 V rating with low impedance characteristics and is compatible with carrier-tape automated placement.

Targeted for demanding environments, this part provides a wide operating temperature range and long-term endurance, making it suitable for applications that require reliable bulk decoupling and smoothing in constrained SMD layouts.

Key Features

• Electrical Performance — 22 µF nominal capacitance at 35 V with ±20% tolerance; low impedance specification of 2.2 Ω supports effective filtering and decoupling.
• Ripple Handling — Specified ripple current of 47.5 mA at 120 Hz and 95 mA at 10 kHz to support AC ripple and switching supply demands.
• Low Loss — tan δ for the 35 V rating is specified at 0.14 (maximum) measured at 120 Hz, 20 °C, indicating controlled dissipation for stable operation.
• Temperature Performance — Rated for operation from −25 °C to +105 °C with low-impedance behavior specified up to +105 °C.
• Long-Life Endurance — Load life rated at 7000 hours at +105 °C; after this test the capacitance change is within ±30% and leakage current meets initial specified limits.
• Leakage Current — After 2 minutes at rated voltage and 20 °C, leakage current is ≤ 0.01 CV or 3 µA (whichever is greater), per datasheet criteria.
• Packaging & Mounting — Chip-type radial can SMD construction designed for automatic mounting with carrier tape; recommended land size is 5.3 × 5.3 mm for PCB layout.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).
• Soldering Robustness — Meets resistance-to-soldering-heat requirements (hot plate 250 °C / 30 s) with capacitance change within ±10% after the test.

Typical Applications

• Automotive electronics — AEC-Q200 qualification, wide temperature range and 7000-hour life at 105 °C make this capacitor suitable for automotive electronic modules that require stable filtering and bulk storage.
• Surface-mount power assemblies — Chip-type SMD radial can compatible with carrier-tape placement for automated PCB assembly and board-level decoupling.
• Power supply filtering — 22 µF/35 V rating, low impedance and defined ripple current ratings support smoothing and local energy storage for power rails and DC/DC converters.
• High-temperature operation — Designed for applications operating up to +105 °C with validated long-life endurance at that temperature.

Unique Advantages

• AEC-Q200 qualification: Provides an automotive-grade reliability baseline for designs requiring industry-recognized component qualification.
• Long high-temperature life: 7000 hours at +105 °C endurance offers predictable aging characteristics for extended deployments.
• Low-impedance performance at elevated temperature: Low-impedance behavior up to +105 °C and a specified impedance value (2.2 Ω) support effective filtering under thermal stress.
• Automated assembly ready: Chip-type SMD radial can packaged for carrier-tape feeding reduces PCB assembly complexity and supports high-volume manufacturing.
• Measured leakage and loss parameters: Datasheet-specified leakage current limits and tan δ values enable precise thermal and loss budgeting in power designs.
• RoHS compliant: Meets current RoHS directives for environmental and regulatory compliance.
