• Thermal Endurance Operating temperature range from -55°C to 125°C with a load life endurance of 3000 hours at 125°C.
• Dissipation Factor tan δ of 0.12 measured at 20°C, 120 Hz, supporting predictable loss characteristics in AC conditions.
• Leakage Current Leakage current specified at 700 µA (after 2 minutes at rated voltage or per datasheet condition), providing a defined leakage envelope for power budgeting.
• Package & Assembly Surface-mount radial can (SMD) package, φ6.3 × 5.7 mm case size, supplied in embossed carrier taping / moisture-proof packing and compatible with lead-free reflow (260°C peak per series datasheet).
• Compliance RoHS compliant.

Typical Applications

• Power supply decoupling — Board-level smoothing and bulk capacitance for low-voltage rails where 120 µF in a compact SMD package is required.
• Switching regulators and DC–DC converters — Supports high-frequency ripple currents (1.05 A at 300 kHz) and low ESR for improved transient response.
• Compact power modules — Small φ6.3 × 5.7 mm footprint provides high capacitance density for space-constrained designs operating across a wide temperature range.

Unique Advantages

• High capacitance in a compact SMD can — 120 µF in a φ6.3 × 5.7 mm case provides substantial bulk capacitance while saving board area.
• High-frequency performance — 25 mΩ ESR at 100 kHz and 1.05 A ripple capability at 300 kHz reduce losses and heat in switching applications.
• Extended high-temperature life — 3000 hours at 125°C delivers predictable endurance for designs exposed to elevated operating temperatures.
• Defined loss and leakage characteristics — tan δ 0.12 (20°C, 120 Hz) and leakage current of 700 µA enable accurate power-loss and leakage budgeting.
• SMD, reflow-capable supply — Supplied in embossed carrier taping and moisture-proof packing and compatible with lead-free reflow processes per series datasheet guidance.
• RoHS compliant — Meets environmental compliance requirements for lead-free assemblies.
