• AEC-Q200 Qualified — Meets AEC-Q200 requirements for applications that demand automotive-grade reliability.
• Capacitance and Voltage — 3.3 mF capacitance at a 10 V rated voltage with ±20% tolerance for stable bulk energy storage and decoupling.
• High Ripple Handling — Supports 938 mA ripple at 120 Hz and 1.4 A at 10 kHz, suitable for smoothing and filtering in power circuits subject to varying frequency content.
• Surface-Mount Can Package — Radial, can-style SMD package for compact PCB integration; package footprint L: 1.83 × W: 1.83 cm and body dimensions L: 2.15 × D: 1.8 cm.
• Vibration Resistance — Chip-type construction specified for vibration resistance, supporting use in mechanically demanding installations.
• Environmental Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Suited for control modules, power distribution, and other in-vehicle electronics that require sustained operation at high temperatures and vibration resistance.
• High-Temperature Power Filtering — Bulk filtering and decoupling in power supplies and converters operating near elevated ambient temperatures.
• Power Management Modules — Energy storage and ripple smoothing in compact SMD power assemblies where board space is constrained but high ripple capability is needed.

Unique Advantages

• Long High-Temperature Load Life — 1000 hours at +150°C provides predictable end-of-life behavior and enables design confidence for extended high-temperature use.
• Automotive-Grade Qualification — AEC-Q200 qualification supports selection in designs that require automotive reliability standards.
• High Ripple Capability Across Frequencies — Specified ripple current at both low (120 Hz) and high (10 kHz) frequencies allows designers to size the capacitor based on real-world switching and ripple spectra.
• Compact SMD Can Format — Radial can-style SMD packaging offers a dense solution for board-level bulk capacitance without through-hole assembly.
• Wide Operating Temperature Range — -55°C to +150°C rating expands usable environments, from cold-start conditions to high-temperature enclosures.
• RoHS Compliance — Conforms to current RoHS requirements for regulatory and environmental consistency.
