PCJ0J821MCL4GS

The PCJ0J821MCL4GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for surface-mount applications requiring low ESR and high ripple-current capability. It combines a compact SMD radial can package with a high capacitance density to support power-rail decoupling and energy buffering in demanding environments.

Built for durability in elevated temperatures, this device is AEC-Q200 qualified, RoHS compliant, and specified for a -55° C to +105° C operating range with a rated load life of 2000 hours at 105° C.

Key Features

• Capacitance & Voltage — 820 μF nominal capacitance with a rated voltage of 6.3 V and ±20% tolerance at 120 Hz, 20° C.
• Low ESR — Equivalent series resistance of 10 mΩ measured at 100 kHz, enabling lower loss and improved transient response.
• High Ripple Current — Rated ripple current of 5.15 A at 100 kHz and 2.575 A at 120 Hz to handle high-frequency and low-frequency ripple in power circuits.
• Thermal Endurance — Rated for continuous operation from -55° C to +105° C with a load life specification of 2000 hours at 105° C.
• Surface-Mount Package — Chip-type radial can SMD package sized L: 12 mm × D: 8 mm with recommended land pattern of 8.3 mm × 8.3 mm for board mounting.
• Assembly Compatibility — Compatible with lead-free reflow soldering conditions up to a 260° C peak (single reflow at 260° C peak correspondence).
• Reliability & Compliance — AEC-Q200 qualified and RoHS (2011/65/EU, (EU)2015/863) compliant for regulated applications.

Typical Applications

• Automotive power electronics — Decoupling and bulk capacitance for DC–DC converters and power-management modules in AEC-Q200 environments.
• Power-rail stabilization — Smoothing and transient suppression on regulated 6.3 V rails where low ESR and high ripple current are required.
• Embedded systems — Compact SMD bulk capacitance for control units and modules operating across -55° C to +105° C.
• High-frequency power stages — Support for switching regulators and converters that demand low loss and high 100 kHz ripple handling.

Unique Advantages

• High ripple-current capability: 5.15 A at 100 kHz and 2.575 A at 120 Hz reduce heating and improve lifespan in ripple-intensive designs.
• Very low ESR: 10 mΩ at 100 kHz minimizes I²R losses and voltage drop under load, improving efficiency and transient response.
• Thermally robust: Rated to +105° C with a 2000-hour load-life specification, supporting long-term operation in elevated-temperature environments.
• Automotive-grade qualification: AEC-Q200 qualification aligns the part with automotive reliability requirements where applicable.
• SMD convenience with reflow compatibility: Chip-type radial can package supports lead-free reflow soldering up to a 260° C peak for modern SMT assembly flows.
• Regulatory compliance: RoHS-compliant construction simplifies use in regulated markets.
