Typical Applications

• General-purpose electronics — compact designs Surface-mount capacitor providing 33 µF/16 V capacitance in a φ5 × 5.7 mm package for space-constrained boards.
• General-purpose electronics — high-frequency support Suitable where higher frequency ripple handling is needed, offering 2.07 A at 300 kHz and low ESR (35 mΩ @100 kHz).
• General-purpose electronics — high-temperature endurance For assemblies requiring operation across −55°C to 105°C and 2000 hours of life at 105°C.

Unique Advantages

• Low impedance at high frequency: 35 mΩ ESR @20°C/100 kHz supports lower AC voltage drop and improved transient response where high-frequency performance matters.
• High ripple-current capability: Rated ripple currents of 207 mA (120 Hz) and 2.07 A (300 kHz) allow the capacitor to handle demanding AC stress in power circuits.
• Compact SMD form factor: φ5 × 5.7 mm package and defined land pattern simplify placement in dense PCB layouts.
• Long-term high-temperature endurance: 2000 hours at 105°C provides predictable life performance under elevated operating temperatures.
• Assembly-ready packaging: Embossed carrier taping with moisture-proof packing supports automated surface-mount assembly processes.
• Regulatory compliance: RoHS compliance supports restricted-substance requirements in product designs.
