• Wide Temperature Range Operating range from −55°C to +125°C to support thermal stress in industrial and high‑temperature environments.
• Surface-Mount Package & Assembly Compact radial can SMD footprint (φ6.3 × 7.7 mm) with recommended land size 6.6 × 6.6 mm; compatible with lead‑free reflow profiles (260°C peak) for modern SMT lines.
• Low Leakage Leakage current specification up to 100 µA after voltage application.
• Packaging & Availability Supplied in embossed carrier taping with moisture proof packing; product is in mass production.
• Environmental Compliance Compliant to the RoHS directive (2011/65/EU, (EU)2015/863) as indicated in the product series documentation.

Typical Applications

• Power supply decoupling and bulk smoothing — Low ESR and high ripple current capability make this capacitor suitable for smoothing output rails and reducing voltage ripple in power converters.
• DC‑DC converter output filters — Compact SMD can package and high-frequency ripple handling support use at converter outputs and point‑of‑load stages.
• Industrial and telecom equipment — Wide −55°C to +125°C temperature range and 3000‑hour life at 125°C address demanding thermal and reliability requirements.
• Embedded systems power filtering — Surface-mount form factor and reflow compatibility simplify assembly for space‑constrained boards.

Unique Advantages

• High ripple tolerance: 1.4 A at 300 kHz and 140 mA at 120 Hz provide robust handling of both high‑frequency and low‑frequency ripple currents, reducing thermal stress in power circuits.
• Low ESR: 30 mΩ at 100 kHz lowers voltage drop and dissipation at switching frequencies, supporting tighter regulation in converters.
• Extended high‑temperature endurance: 3000 hours at 125°C under rated voltage ensures long-term stability where elevated ambient temperatures are common.
• SMT-friendly package: φ6.3 × 7.7 mm SMD radial can with reflow compatibility up to 260°C enables automated assembly and reliable solder joints.
• Production-ready packaging: Embossed carrier taping and moisture proof packing streamline pick-and-place operations and storage handling.
• Regulatory alignment: RoHS compliance as stated in the series documentation supports deployment in regulated regions.
