PCS1A121MCL1GS

The PCS1A121MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in an SMD chip-style can designed for long-life applications. It delivers 120 µF capacitance at a 10 V rating with low ESR and high ripple handling, aimed at demanding electronic systems where durability and stable performance over temperature are required.

Engineered for applications that require extended endurance and wide temperature performance, this capacitor supports automotive-grade qualification (AEC-Q200) and is RoHS compliant, making it suitable for reliable systems-level designs in harsh environments.

Key Features

• Capacitance & Voltage: 120 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance for predictable energy storage and decoupling.
• Low ESR: 27 mΩ equivalent series resistance measured at 100 kHz, enabling improved ripple performance and reduced dissipation in power circuits.
• High Ripple Current Capability: 1.15 A at 120 Hz and 2.3 A at 100 kHz to support switching regulators and power conversion applications.
• Long Life Endurance: Load life specified at 5000 hours at 105°C, providing extended operational lifetime under elevated temperature stress.
• Temperature Range: Rated for operation from −55°C to +105°C to cover a broad range of environmental conditions.
• SMD, Lead-Free Reflow Compatible: Chip-type can in an SMD package designed for lead-free reflow soldering with a 260°C peak correspondence (single reflow per datasheet conditions).
• Automotive-Grade Reliability: AEC-Q200 qualified and RoHS compliant for use in regulated manufacturing environments.
• Compact Package: Package dimensions L: 6 × D: 6.3 mm with a recommended land pattern of 6.6 × 6.6 mm for compact PCB layouts.
• Polarized Construction: Polarized capacitor type appropriate for DC power filtering and bulk decoupling functions.

Typical Applications

• Automotive Electronics: Power supply smoothing and decoupling in control modules where AEC-Q200 qualification and extended temperature range are required.
• Power Conversion Modules: Output filtering and energy buffering for DC–DC converters and regulator stages benefiting from low ESR and high ripple current ratings.
• Industrial Control Systems: Bulk decoupling and transient suppression in industrial electronics operating across wide temperature ranges and sustained thermal stress.

Unique Advantages

• Extended High‑Temperature Endurance: 5000 hours at 105°C supports designs that must maintain capacitance and ESR stability under prolonged thermal load.
• High Ripple Handling with Low Losses: Low ESR (27 mΩ at 100 kHz) combined with specified ripple current ratings reduces heating and improves efficiency in switching applications.
• Automotive-Grade Qualification: AEC-Q200 qualification and RoHS compliance streamline adoption into regulated automotive and transportation systems.
• SMD Can for Compact Layouts: Small 6 × 6.3 mm footprint and recommended land size (6.6 × 6.6 mm) simplify PCB integration in space-constrained designs.
• Lead-Free Reflow Compatibility: Designed for lead-free reflow soldering conditions up to a 260°C peak (per datasheet), supporting modern assembly processes.
