• Voltage Rating Rated for 50 V operation.
• Low Loss / Low ESR ESR of 25 mΩ measured at 20°C and 100 kHz, and tanδ (DF) of 0.12 at 20°C, 120 Hz for efficient high-frequency performance.
• High Ripple Current Handling Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz) to support demanding ripple conditions.
• Reliability & Endurance Load-life rated for 3000 hours at 125°C, with specified limits for capacitance change, tanδ and ESR after endurance testing.
• Temperature Range Operable from −55°C to +125°C.
• Package & Assembly φ10 × 12.4 mm can-style SMD (radial, can - SMD) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering up to a 260°C peak as specified in the datasheet.
• Leakage Current Specified leakage current of 250 µA.
• Compliance RoHS compliant.

Typical Applications

• General-Purpose Power Filtering — Use on power rails where a 100 µF, 50 V capacitor with low ESR (25 mΩ) and high ripple-current capability reduces voltage ripple and improves stability.
• High-Frequency Decoupling — The low loss (tanδ = 0.12 at 120 Hz) and 1.6 A high-frequency ripple rating support decoupling in systems with significant high-frequency switching activity.
• Industrial and Embedded Electronics — Wide −55°C to +125°C operating range and 3000-hour endurance at 125°C suit long-life, thermally demanding equipment designs.

Unique Advantages

• Low ESR for Improved Efficiency: 25 mΩ ESR at 100 kHz reduces resistive losses and supports tighter voltage regulation in power circuits.
• High Ripple Handling: Rated ripple currents (160 mA at 120 Hz and 1.6 A at 300 kHz) allow the capacitor to absorb both low- and high-frequency ripple components.
• Extended High-Temperature Endurance: 3000 hours at 125°C provides predictable long-term behavior in elevated-temperature environments.
• SMD Packaging with Moisture Protection: Embossed carrier taping and moisture-proof packing streamline automated assembly and storage handling.
• Lead-Free Reflow Compatible: Specified for lead-free reflow up to 260°C peak, enabling modern surface-mount production flows.
• RoHS Compliant: Meets RoHS requirements for environmentally restricted substances.
