Key Features

• Capacitance & Rated Voltage — 82 µF capacitance with an 80 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Low ESR for High-Frequency Use — Equivalent series resistance of 28 mΩ at 100 kHz to minimize loss and improve filtering in high-frequency circuits.
• High Ripple-Current Capability — Supports 3.1 A ripple current at 100 kHz and 1.55 A at 120 Hz for robust handling of switching currents.
• Long Life & Endurance — Rated for 4000 hours at 125°C under endurance conditions, providing extended service in elevated-temperature applications.
• AEC‑Q200 and RoHS Compliant — AEC‑Q200 rating and RoHS (2011/65/EU, (EU)2015/863) compliance for regulated and automotive environments.
• Surface-Mount Chip Package — Compact radial can SMD chip form factor with body dimensions L: 1.27 × D: 1.00 cm and recommended land size L: 1.03 × W: 1.03 cm for PCB integration.
• Lead‑Free Reflow Ready — Compatible with lead‑free reflow soldering; supports peak reflow temperatures up to 260°C per the PCA series soldering profile.
• Wide Operating Temperature — Rated for −55°C to +125°C to cover automotive and industrial thermal ranges.

Typical Applications

• Automotive Power Modules — Energy storage and smoothing in power rails for ECUs and power-distribution modules where AEC‑Q200 qualification and wide temperature range are required.
• DC–DC Converters — Output and intermediate filtering in high-frequency switching supplies, leveraging low ESR and high ripple-current capability to improve converter stability and efficiency.
• Industrial Power Control — Bulk and decoupling in industrial power electronics that operate at elevated temperatures and require long endurance.
• High-Frequency Power Supplies — Filtering and energy buffering in high-frequency applications where the 100 kHz ESR and ripple specifications are critical to performance.

Unique Advantages

• Designed for High-Frequency Performance: 28 mΩ ESR at 100 kHz and specified 100 kHz ripple current (3.1 A) reduce losses and thermal rise in switching applications.
• Extended High-Temperature Life: 4000 hours at 125°C endurance rating supports reliability in hot environments and long-term deployments.
• Automotive-Grade Qualification: AEC‑Q200 compliance supports use in automotive systems that demand component-level reliability.
• Surface-Mount, Reflow-Compatible Package: Chip SMD form factor and 260°C peak reflow compatibility simplify automated assembly and thermal processing workflows.
• Regulatory Compliance: RoHS conformity ensures alignment with environmental directives for commercial and regulated markets.
