PCA1V221MCL1GS

The PCA1V221MCL1GS is a high-reliability, conductive-polymer aluminum solid electrolytic capacitor in an SMD radial-can package. It delivers low ESR and high ripple-current capability with a 220 µF capacitance at a 35 V rating, designed for demanding thermal and power conditions.

Targeted for automotive and other high-temperature applications, this part combines AEC-Q200 compliance, a wide operating range (-55 °C to +125 °C), and a 4000-hour endurance rating at 125 °C to provide durable filtering and decoupling in compact surface-mount designs.

Key Features

• Construction: Conductive-polymer aluminum solid electrolytic, chip type with high-reliability design.
• Capacitance & Voltage: 220 µF nominal capacitance, rated at 35 V with tolerance -20% to +20% (measured at 120 Hz, 20 °C).
• Low ESR & High Ripple Capability: ESR = 21 mΩ (measured at 100 kHz, 20 °C); ripple current handling of 3.9 A at 100 kHz and 1.95 A at 120 Hz.
• High-Temperature Endurance: Rated operating temperature -55 °C to +125 °C with a guaranteed lifetime of 4000 hours at 125 °C.
• Automotive-Grade Reliability: AEC-Q200 compliant and specified ESR behavior after endurance at -40 °C.
• SMD Package & Reflow Compatibility: Surface-mount radial can (L: 1.2 × D: 0.8 cm) with recommended land size 8.3 × 8.3 mm; compatible with lead-free reflow soldering up to a 260 °C peak.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power electronics: Bulk and rail filtering in automotive ECUs and power modules where AEC-Q200 qualification and high-temperature endurance are required.
• Power-supply filtering and decoupling: Input/output smoothing and transient suppression for converters thanks to low ESR and high ripple-current capability.
• DC–DC converters and regulators: Output decoupling and stability support under high-frequency switching conditions (specified ripple at 100 kHz).
• High-temperature ruggedized electronics: Use in applications that operate continuously at elevated temperatures, taking advantage of the 125 °C rating and 4000-hour life.

Unique Advantages

• High ripple tolerance: Supports up to 3.9 A at 100 kHz, enabling reliable operation with high-frequency switching supplies.
• Very low ESR: 21 mΩ ESR at 100 kHz reduces I²R losses and improves converter efficiency under load.
• Extended high-temperature life: 4000 hours at 125 °C provides predictable long-term performance in thermal stress environments.
• AEC-Q200 qualification: Facilitates selection for automotive-grade designs requiring supplier-recognized reliability.
• Lead-free reflow capable: SMD radial-can package supports lead-free reflow up to a 260 °C peak for modern assembly processes.
• Compact SMD footprint: Small can dimensions and defined land pattern (8.3 × 8.3 mm) simplify PCB layout in space-constrained designs.
