• Voltage Rating  Rated for 50 V operation.
• Low Loss / Dissipation  tanδ (DF) = 0.12 measured at 20 °C, 120 Hz for controlled AC loss.
• Low ESR  ESR = 30 mΩ at 20 °C, 100 kHz supporting high-frequency performance.
• High Ripple Capability  Low-frequency ripple current 160 mA at 120 Hz and high-frequency ripple current 1.6 A (1600 mA) at 300 kHz.
• Leakage Current  Specified leakage current up to 100 µA (after standard conditioning).
• Lifetime & Temperature  Rated for 3000 hours endurance at 125 °C; operating range −55 °C to 125 °C.
• Package & Mounting  Radial can SMD package (φ8 × 8.7 mm length); supplied in embossed carrier taping with moisture-proof packing and compatible with lead‑free reflow profiles up to 260 °C per series guidance.
• Compliance  RoHS‑compliant.

Typical Applications

• Power module filtering  Use where compact SMD bulk or output filtering is needed at 50 V and high ripple conditions.
• High-frequency power supplies  Suited to circuits requiring low ESR and reliable high‑frequency ripple handling.
• Thermally demanding electronics  Applicable in designs that require continuous operation across −55 °C to 125 °C and long endurance at elevated temperature.

Unique Advantages

• High ripple tolerance: 1.6 A high‑frequency ripple rating combined with low ESR supports sustained ripple handling in compact SMD form.
