Targeted for automotive and industrial applications, this part combines 510 µF capacitance with a 100 V rated voltage, AEC-Q200 qualification, RoHS compliance and a 5000-hour endurance at 105°C to support demanding power circuitry and automated assembly processes.

Key Features

• Capacitance & Voltage — 510 µF nominal capacitance with a 100 V rated voltage and tolerance of -20% to +20%.
• Low-impedance chip construction — Chip type, low-impedance design for stable performance in power applications.
• Loss characteristics — tanδ (DF) of 0.07 measured at 20°C, 120 Hz for predictable AC loss performance.
• Ripple handling — Low-frequency ripple current 1.07 A (120 Hz) and high-frequency ripple current 2.14 A (10 kHz) to support smoothing and decoupling under dynamic loads.
• Leakage current — Specified leakage current of 510 µA after initial voltage application at 20°C.
• High-temperature endurance — Rated for 5000 hours at 105°C under rated voltage conditions.
• Package & mounting — Surface-mount radial can (φ18 × 21.5 mm) supplied in embossed carrier taping for automatic pick-and-place. Recommended land size: 18.3 mm × 18.3 mm.
• Environmental & quality — RoHS compliant and AEC-Q200 qualified; product available in mass production status.

Typical Applications

• Automotive power electronics — Bulk energy storage and smoothing on high-voltage rails where 100 V capability and high capacitance are required.
• Automotive control modules — Decoupling and ripple filtering for electronic control units that require AEC-Q200–qualified components.
• Automated PCB assembly — Designed for use with automatic mounting machines and shipped in embossed carrier tape for efficient pick-and-place processing.

Unique Advantages

• High voltage and high capacitance in an SMD package: 100 V rating with 510 µF capacitance provides substantial energy storage in a surface-mount radial can.
• Low-impedance performance: Chip-type construction and a low tanδ (0.07 at 120 Hz, 20°C) support efficient AC performance and reduced ripple-related heating.
• Designed for ripple-intensive applications: Specified LF and HF ripple currents (1.07 A at 120 Hz, 2.14 A at 10 kHz) enable use in dynamic power circuits.
• High-temperature endurance: 5000 hours at 105°C guarantees extended life under elevated operating temperatures when used within rated conditions.
• Quality and compliance: AEC-Q200 qualification and RoHS compliance support regulated and reliability-conscious designs.
• Production-ready packaging: Embossed carrier taping and mass-production availability streamline procurement and assembly for volume manufacturing.
