PCJ0G681MCL1GS

The PCJ0G681MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD radial can package, offering high capacitance and low equivalent series resistance (ESR) for demanding power applications. It is designed for automotive electronics where sustained high ripple current handling and thermal endurance are required.

Key value comes from a combination of 680 µF capacitance at 4 V, low ESR, high ripple current ratings, AEC-Q200 qualification and RoHS compliance, plus compatibility with lead‑free reflow soldering profiles up to a 260°C peak.

Key Features

• Capacitance & Rated Voltage — 680 µF nominal capacitance at a rated voltage of 4 V with ±20% tolerance (120 Hz, 20°C).
• Low ESR — 13 mΩ equivalent series resistance measured at 100 kHz, enabling reduced power loss and improved filtering performance at switching frequencies.
• High Ripple Current — Rated for 1.975 A at 120 Hz and 3.95 A at 100 kHz to support high-ripple power stages.
• Thermal Range & Endurance — Operating temperature range of −55°C to +105°C with a specified load life of 2000 hours at 105°C.
• AEC‑Q200 Qualified — Meets automotive-grade reliability standards for use in vehicle electronics.
• Surface-Mount Radial Can — Chip-type SMD package, body size 8 × 8 mm and recommended land size 8.3 × 8.3 mm for compact board layout.
• Manufacturing & Environmental — Lead‑free reflow soldering condition correspondence to a 260°C peak and RoHS compliant (2011/65/EU, (EU)2015/863).
• Polarized Device — Polarized construction for use where electrolytic capacitance is required.

Typical Applications

• Automotive power electronics — Low ESR and high ripple current ratings make this part suitable for vehicle power systems requiring robust smoothing and decoupling.
• DC‑DC converter outputs — High capacitance and low ESR provide effective output filtering at switching frequencies (performance characterized at 100 kHz).
• Power management modules — Endurance of 2000 hours at 105°C supports reliable operation in thermally demanding environments.

Unique Advantages

• Reduced thermal losses: 13 mΩ ESR at 100 kHz lowers resistive heating under heavy ripple conditions.
• Handles high switching ripple: 3.95 A ripple current rating at 100 kHz supports high-frequency power stages and converters.
• Extended high-temperature endurance: 2000 hours at 105°C provides long-term reliability in elevated-temperature deployments.
• Automotive-grade qualification: AEC‑Q200 qualification aligns the device with automotive reliability expectations.
• Compact SMD form factor: 8 × 8 mm package delivers 680 µF capacitance in a small board footprint.
• Production-ready compliance: RoHS compliant and compatible with lead‑free reflow processes up to a 260°C peak.
