The PCJ1C331MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for surface-mount applications. It combines low ESR and high ripple-current capability with a compact SMD can package, making it suitable for demanding electronic power circuits in automotive systems.

Key attributes include a 330 µF capacitance at 16 V, AEC-Q200 qualification, RoHS compliance, and a rated operating temperature range of −55 °C to +105 °C with a 2000-hour load life at 105 °C.

Key Features

• Core Dielectric and Construction Conductive polymer aluminum solid electrolytic design providing higher capacitance and low equivalent series resistance (ESR).
• Electrical Performance 330 µF capacitance at 16 V with ±20% tolerance; ESR specified at 16 mΩ (measured at 100 kHz, 20 °C).
• High Ripple Current Engineered for elevated ripple handling: 2.175 A at 120 Hz and 4.35 A at 100 kHz, supporting high-stress power rails.
• Thermal Endurance Rated for −55 °C to +105 °C operating range and validated for 2000 hours at 105 °C under rated voltage.
• Package and Assembly Chip-type SMD can (radial, can - SMD) suitable for lead-free reflow soldering; designed for peak reflow up to 260 °C (single reflow at 260 °C).
• Automotive-Grade Qualification AEC-Q200 qualified and compliant with RoHS directive (2011/65/EU, (EU)2015/863) for regulated material requirements.
• Compact Footprint Small 1.0 × 1.0 cm component size with recommended land pattern of 1.03 × 1.03 cm for high-density board layouts.

Typical Applications

• Automotive power electronics — Use for bulk decoupling and smoothing on automotive power rails where low ESR and high ripple current are required.
• ECU and module power supplies — Stabilizes voltage rails in electronic control units across temperature extremes up to 105 °C.
• On-board DC–DC converters — Supports high-frequency switching environments with low ESR and high ripple current capability.
• SMD board-level designs — Compact chip package facilitates space-constrained PCB layouts in vehicle electronic systems.

Unique Advantages

• Low ESR for improved transient response: 16 mΩ ESR at 100 kHz reduces voltage ripple and improves regulator stability.
• High ripple-current capability: Rated ripple currents (2.175 A at 120 Hz, 4.35 A at 100 kHz) enable reliable operation under demanding switching loads.
• Designed for elevated-temperature endurance: 2000-hour load life at 105 °C helps ensure long-term reliability in hot environments.
• Automotive qualification: AEC-Q200 rating supports use in automotive electronic subsystems requiring industry-recognized reliability.
• Lead-free reflow compatibility: SMD construction and specified reflow conditions (up to 260 °C peak, single reflow) simplify modern assembly processes.
• Regulatory compliance: RoHS-compliant materials meet restricted substance requirements.
