Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, providing substantial energy storage in a single SMD component.
• Low-Impedance Performance — Chip-type, low-impedance construction for improved high-frequency response and stable operation across the specified temperature range.
• Ripple Current Capability — Low-frequency ripple current of 835 mA at 120 Hz and high-frequency ripple handling up to 1.67 A (high-frequency values listed in product data), enabling effective smoothing in power circuits.
• Reliability & Endurance — Rated lifetime of 5000 hours at 105°C per the datasheet endurance specification.
• Operating Temperature Range — Specified to operate from −55°C to +105°C to address elevated-temperature applications.
• Package & Mounting — Surface-mount, radial can SMD package with dimensions φ18 × 16.5 mm (L), supplied in embossed carrier taping for pick-and-place compatibility; surface mount land size specified as 1.83 × 1.83 cm.
• Automotive Qualification & Compliance — AEC-Q200 rated and RoHS compliant, supporting regulated environmental and quality requirements.
• Leakage Current — Specified leakage current of 330 µA (per product data), supporting predictable standby characteristics in designs.

Typical Applications

• Automotive Electronic Systems — AEC-Q200 qualification and a 100 V/330 µF rating make this capacitor suitable for vehicle electronic modules that require reliable SMD capacitors.
• Power Supply Modules — Surface-mount configuration and measurable ripple-current ratings support board-level smoothing and decoupling in high-voltage power assemblies.
• High-Voltage SMD Assemblies — Compact chip-type can in embossed tape packaging for automated production of designs that require 100 V-rated electrolytic capacitance.

Unique Advantages

• AEC-Q200 Qualification: Provides a documented reliability baseline for automotive and other high-reliability applications.
• High Voltage and High Capacitance: 330 µF at 100 V reduces the number of components required to achieve board-level energy storage.
• Low Impedance with Defined Ripple Capability: 835 mA @ 120 Hz and up to 1.67 A at high frequency give designers explicit ripple-handling data for power filtering and regulation.
• Extended Endurance at Elevated Temperature: Rated for 5000 hours at 105°C, enabling predictable long-term performance in thermal stress environments.
• SMD-Friendly Packaging: Embossed carrier taping and compact chip-type can support automated pick-and-place assembly and reduce BOS complexity.
• Regulatory Compliance: RoHS compliant to support environmentally restricted product requirements.
