PCJ0J821MCL1GS

The PCJ0J821MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for surface-mount assembly. It delivers high capacitance with low equivalent series resistance (ESR) and high ripple-current capability, targeting demanding automotive electronics environments.

Key attributes include AEC-Q200 qualification, RoHS compliance, a 2000-hour load life at 105°C, and compatibility with lead‑free reflow soldering up to a 260°C peak. These characteristics make it suitable for automotive applications that require robust, long‑life decoupling and energy-storage components.

Key Features

• Electrical Performance — 820 µF capacitance at 6.3 V rated voltage with ±20% tolerance; polarized design for bulk energy storage and decoupling.
• Low ESR — 13 mΩ ESR measured at 100 kHz, enabling lower conduction losses and improved transient response.
• High Ripple Current — Rated ripple current of 2.25 A at 120 Hz and 4.5 A at 100 kHz to support demanding AC and switching environments.
• Temperature & Endurance — Operating range −55°C to +105°C with a specified load life of 2000 hours at 105°C, meeting endurance criteria for extended high‑temperature operation.
• Package & Assembly — Chip SMD (radial can style) with dimensions L: 0.8 × D: 1 cm and recommended land size L: 1.03 × W: 1.03 cm; compatible with lead‑free reflow soldering (260°C peak correspondence).
• Automotive Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated automotive design requirements.

Typical Applications

• Automotive power electronics — Bulk energy storage and filtering in automotive power modules where low ESR and high ripple handling are required.
• Electronic control units (ECUs) — Decoupling and smoothing in control modules that operate across −55°C to +105°C and require long life at elevated temperatures.
• In-vehicle systems — Support for infotainment, body control, and sensor interface circuits that demand reliable SMD capacitors with automotive qualification.

Unique Advantages

• High capacitance in an SMD chip — 820 µF in a compact package provides significant bulk storage while minimizing board area.
• Low ESR for improved power integrity — 13 mΩ ESR at 100 kHz reduces voltage drop and heat generation in high-current switching environments.
• Robust ripple-current capability — 4.5 A at 100 kHz (and 2.25 A at 120 Hz) supports high-frequency switching supplies and converters.
• Designed for elevated-temperature endurance — 2000 hours at 105°C supports long-term reliability in under‑hood and other high‑temperature automotive locations.
• Manufacturing-friendly — SMD form factor and compatibility with lead‑free reflow up to 260°C simplify assembly and reflow process integration.
• Regulatory and industry readiness — AEC‑Q200 qualification and RoHS compliance streamline adoption in regulated automotive designs.
