Key Features

• Capacitance & Voltage — 120 µF rated capacitance at 50 V, ±20% tolerance for bulk energy storage in compact SMD form.
• Low ESR — 25 mΩ ESR measured at 20°C and 100 kHz, supporting lower dissipation and improved transient response.
• High Ripple Current — 1.05 A at 120 Hz (low frequency) and 2.1 A at 100 kHz (high frequency) for robust smoothing and decoupling under dynamic loads.
• Loss Characteristics — tan δ of 0.08 (20°C, 120 Hz) for predictable AC loss behavior in circuit designs.
• Leakage Current — 180 µA typical leakage, suitable for applications where low standby leakage is important.
• High-Temperature Endurance — Rated for operation from -55°C to +135°C with a life/endurance rating of 4000 hours at 135°C.
• AEC-Q200 Qualified — Qualification suitable for automotive-grade designs requiring component-level reliability verification.
• Surface-Mount Chip Package — Compact φ8 × 12 mm package (12.0 × 8.0 mm) with recommended land size 8.3 × 8.3 mm; supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Lead-Free Reflow Compatible — Conforms to lead-free reflow soldering conditions with peak temperatures up to 260°C.
• RoHS Compliant — Manufactured to meet applicable RoHS requirements.

Typical Applications

• Automotive power systems — AEC-Q200 qualification, wide temperature range and 4000 h endurance at 135°C make this capacitor suitable for underhood and vehicle electronic modules requiring reliable bulk capacitance.
• High-temperature industrial electronics — Operation to +135°C and long-term endurance support demanding industrial environments where elevated ambient temperatures are common.
• Power conversion and filtering — Low ESR and high ripple-current capability enable effective smoothing and decoupling in DC–DC converters and power-supply stages.

Unique Advantages

• High-temperature reliability: 4000 hours at 135°C delivers extended lifetime in thermally stressed applications, reducing replacement frequency and maintenance.
• Superior ripple handling: Dual-specified ripple currents at low and high frequency (1.05 A / 2.1 A) minimize voltage ripple and heating in high-duty circuits.
• Low dissipation losses: 25 mΩ ESR at 100 kHz and tan δ of 0.08 help preserve efficiency in high-frequency power stages.
• Automotive-ready qualification: AEC-Q200 status supports use in vehicle electronics that demand component-level reliability documentation.
• Assembly-friendly packaging: SMD chip format with embossed carrier taping and moisture-proof packing streamlines automated placement and reflow processes.
• Regulatory compliance: RoHS conformity supports deployment in regions and products requiring restricted-substance compliance.
