PCS0J121MCL9GS

The PCS0J121MCL9GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for surface-mount assembly and long-life applications. It delivers 120 µF at 6.3 V in a compact can-style SMD package and is intended for demanding environments where reliability and thermal endurance are required.

Engineered for automotive use, the device combines low ESR and robust ripple-current capability with a 5000-hour load life at 105°C, AEC-Q200 qualification, lead-free reflow compatibility and RoHS compliance to support qualification-driven designs.

Key Features

• Electrolyte and construction — Conductive polymer aluminum solid electrolyte in a chip-type, can-style SMD package for stable electrical performance.
• Rated values — 120 µF capacitance at 6.3 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Low ESR and ripple handling — ESR of 22 mΩ measured at 100 kHz and ripple-current ratings of 1.4 A at 120 Hz and 2.8 A at 100 kHz for high-frequency and low-frequency decoupling demands.
• Long-life endurance — Load life specified as 5000 hours at 105°C, with endurance specifications restored to 20°C after test.
• Temperature range — Rated for operation from −55°C to +105°C to cover broad thermal conditions.
• Assembly and compliance — SMD device compatible with lead-free reflow soldering (260°C peak correspondence) and compliant to RoHS (2011/65/EU, (EU)2015/863). AEC-Q200 qualified.
• Compact footprint — Can-style SMD package with dimensions L: 6 × D: 6.3 mm and recommended land size L: 6.6 × W: 6.6 mm for PCB layout.

Typical Applications

• Automotive electronic modules — Suited for use in automotive modules where AEC-Q200 qualification and long life at elevated temperature (5000 h at 105°C) are required.
• On-board power regulation — Low ESR (22 mΩ at 100 kHz) and rated ripple currents support power-supply decoupling and local energy storage in vehicle electronics.
• Infotainment and telematics — Compact SMD can package and reflow compatibility enable integration into space-constrained automotive infotainment and telematics PCBs.
• Sensor and control units — Wide operating temperature range (−55°C to +105°C) and AEC-Q200 qualification make it appropriate for sensor and control electronics exposed to varying temperatures.

Unique Advantages

• Long-term thermal endurance: 5000-hour load life at 105°C provides predictable aging and planning for lifecycle-critical designs.
• Automotive-qualified: AEC-Q200 qualification supports use in designs requiring automotive reliability standards.
• High ripple capability with low ESR: 22 mΩ ESR at 100 kHz and specified ripple currents enable effective decoupling and noise suppression at both low and high frequencies.
• Lead-free reflow ready: Designed for lead-free reflow soldering (260°C peak correspondence), simplifying surface-mount assembly and process compatibility.
• RoHS compliant: Conforms to RoHS directives (2011/65/EU, (EU)2015/863) for environmental and regulatory alignment.
• Compact PCB footprint: Small can-style SMD dimensions and recommended land pattern support space-constrained layouts.
