PCA1J121MCL1GS

The PCA1J121MCL1GS is a high-reliability conductive polymer aluminum solid electrolytic chip capacitor in an SMD radial can package. It delivers low equivalent series resistance and high ripple-current capability, designed for applications that require robust power filtering and long-term performance across a wide temperature range.

Targeted for demanding electronics environments, this part combines a 120 µF capacitance at 63 V with AEC‑Q200 compliance, a long 4000-hour life at 125°C, and lead‑free reflow compatibility to support modern assembly and thermal profiles.

Key Features

• Capacitance & Voltage — 120 µF rated capacitance at 63 V, with capacitance tolerance ±20% (measured at 120 Hz, 20°C).
• Low ESR & High Ripple Handling — ESR of 24 mΩ measured at 100 kHz and specified ripple currents of 2.3 A at 120 Hz and 4.6 A at 100 kHz for effective smoothing and decoupling under high ripple stress.
• Long High‑Temperature Life — Designed for 4000 hours of operation at 125°C under rated DC bias plus rated ripple current, with specified limits on capacitance change and ESR after endurance.
• Wide Temperature Range — Rated for operation from −55°C to +125°C, with impedance stability specified across the range.
• Surface‑Mount Radial Can Package — SMD radial/can construction with overall dimensions L: 1.27 cm × D: 1.00 cm and recommended land size L: 1.03 cm × W: 1.03 cm for PCB mounting.
• Assembly & Environmental — Lead‑free reflow compatible to a 260°C peak (pre‑heat and time limits apply) and RoHS compliant. AEC‑Q200 compliant for designs requiring that qualification.
• ESR Performance After Stress — ESR specified at 100 kHz after endurance and at −40°C, supporting reliable low‑temperature operation post‑stress.

Typical Applications

• Automotive power electronics — AEC‑Q200 compliance and extended high‑temperature life make this capacitor suitable for automotive electronic modules requiring stable filtering and energy buffering.
• Power supply input/output filtering — Low ESR (24 mΩ at 100 kHz) and high ripple current ratings support smoothing and decoupling in DC‑DC converters and voltage regulators.
• On‑board bulk and decoupling — 120 µF at 63 V provides bulk capacitance for intermediate DC links and local energy storage on compact SMD layouts.
• Harsh‑environment electronics — Wide operating temperature (−55°C to +125°C) and proven endurance at elevated temperatures suit equipment exposed to thermal stress.

Unique Advantages

• High ripple tolerance: Specified ripple currents of 2.3 A (120 Hz) and 4.6 A (100 kHz) enable effective handling of dynamic load currents without compromising lifetime.
• Low loss at high frequency: 24 mΩ ESR at 100 kHz reduces heat generation and improves filtering efficiency in high‑frequency power stages.
• Extended high‑temperature durability: 4000 hours at 125°C under rated conditions provides predictable aging and lifecycle planning for thermal designs.
• Qualification for demanding designs: AEC‑Q200 compliance supports use in regulated environments where component qualification is required.
• Reflow‑ready SMD format: Lead‑free reflow compatibility to 260°C peak allows integration with modern assembly processes while maintaining performance limits specified for soldering heat.
• Stable performance after stress: ESR and capacitance limits after endurance and damp‑heat tests are specified, aiding reliability assessments for long‑term deployments.
