PCJ1A681MCL1GS

The PCJ1A681MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for surface-mount applications. It delivers high capacitance and low equivalent series resistance (ESR) in a compact radial can SMD package.

Engineered for automotive environments, the part combines a 680 µF, 10 V rating with AEC‑Q200 qualification, wide operating temperature range and extended load-life characteristics to support power-dense designs that require stable performance under thermal and ripple stress.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 10 V provides substantial bulk energy storage for decoupling and power smoothing in compact assemblies.
• Low ESR — 13 mΩ equivalent series resistance measured at 100 kHz, enabling improved ripple handling and reduced heat generation under high-frequency current.
• High Ripple Current — Rated ripple current of 2.41 A at 120 Hz and 4.82 A at 100 kHz to support demanding dynamic loads.
• Extended Endurance — Load life specified at 2000 hours at 105°C, with defined limits for capacitance change, tan δ and ESR after endurance testing.
• Automotive Qualification — AEC‑Q200 qualified for use in automotive electronic designs that require industry-recognized component-level reliability.
• Wide Temperature Range — Specified operating range from −55°C to +105°C for stable performance across automotive temperature extremes.
• SMD Package & Reflow Compatibility — Chip-type radial can SMD construction with lead-free reflow soldering correspondence up to a 260°C peak, suitable for modern surface-mount assembly processes.
• Manufacturing & Compliance — RoHS compliant (2011/65/EU, (EU)2015/863) and marked with navy blue print on the case top for identification.
• Mechanical Footprint — Compact sizing (L × D: 1 × 1 cm) with a recommended land pattern of 1.03 × 1.03 cm for PCB layout.

Typical Applications

• Automotive electronic modules — Suited for power management and electronic control units where AEC‑Q200 qualification and thermal endurance are required.
• Power rails and decoupling — Low ESR and high ripple current ratings make the capacitor appropriate for stabilizing DC power rails in demanding environments.
• SMD assembly workflows — Designed for surface-mount production with lead‑free reflow correspondence to common PCB assembly processes.

Unique Advantages

• High capacitance in a compact chip — 680 µF in a 1 × 1 cm footprint reduces board area compared with discrete larger components.
• Low-frequency and high-frequency performance — Measured ripple current ratings at both 120 Hz and 100 kHz accommodate a range of switching and ripple conditions.
• Thermal endurance — 2000-hour load-life at 105°C demonstrates sustained electrical characteristics under elevated temperatures.
• Automotive-grade reliability — AEC‑Q200 qualification provides objective verification of suitability for automotive electronics.
• RoHS compliance — Meets current RoHS requirements for lead-free system designs.
• Predictable ESR behavior — ESR specified at 100 kHz (13 mΩ) supports deterministic thermal and ripple loss calculations during system design.
