It delivers low ESR and high ripple-current capability in a compact φ8 × 8.7 mm SMD can, targeting general-purpose power applications.

Designed for elevated-temperature operation and long life, this part is specified for operation from −55 °C to 105 °C with a rated endurance of 5000 hours at 105 °C. Packaging is optimized for automated assembly with embossed carrier taping and moisture-proof packing; the device is in mass production.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20% at 20 °C, 120 Hz.
• Low Dissipation Factor — tan δ = 0.12 specified at 20 °C, 120 Hz, helping maintain efficient AC performance.
• Low ESR — Equivalent Series Resistance of 16 mΩ measured at 20 °C/100 kHz for reduced loss and improved thermal performance.
• High Ripple Current Capability — Rated ripple current of 407 mA at 120 Hz (low frequency) and 4.07 A at 300 kHz (high frequency), supporting demanding power-conditioning tasks.
• Leakage Current — Specified leakage current of 1056 µA after 2 minutes at 20 °C under rated voltage.
• Robust Endurance — 5000-hour load life at 105 °C under rated voltage with defined limits for capacitance change, tan δ, ESR and leakage.
• Compact SMD Can — Case size φ8 × 8.7 mm (L × D) with recommended land pattern L: 8.3 mm × W: 8.3 mm for surface-mount assembly.
• Assembly Compatibility — SMD type designed for lead-free reflow soldering conditions with a 260 °C peak reflow correspondence.
• Environmental Compliance — RoHS-compliant construction.

Typical Applications

• Power supply decoupling — Low ESR and high ripple-current capability suit bulk smoothing and decoupling in SMD power rails.
• DC–DC converter output filtering — 330 µF at 16 V combined with 16 mΩ ESR supports output filter stability and transient load handling.
• General-purpose SMD designs — Compact φ8 can and embossed carrier taping make the part appropriate for automated placement in embedded and industrial electronics.

Unique Advantages

• High ripple handling — Rated 4.07 A at 300 kHz and 407 mA at 120 Hz reduces thermal stress on the capacitor in high-frequency converter environments.
• Low ESR for efficiency — 16 mΩ ESR at 100 kHz minimizes conduction losses and helps improve overall power-conversion efficiency.
• Extended high-temperature life — 5000-hour endurance at 105 °C provides predictable long-term performance in elevated-temperature applications.
• SMD-ready packaging — Embossed carrier taping and moisture-proof packing allow straightforward integration into automated SMT assembly flows.
• Clear electrical limits — Specified tan δ (0.12), leakage current (1056 µA), and tolerance (±20%) enable accurate margining during design.
