Key Features

• Capacitance & Voltage — 220 µF rated capacitance with a 10 V nominal voltage and ±20% tolerance, providing bulk energy storage for local power decoupling and filtering.
• Low Loss Characteristics — Tangent of loss angle (tanδ) of 0.24 measured at 20°C, 120 Hz, 10 V, supporting predictable impedance and dissipation behavior at typical operating frequencies.
• Ripple Current Performance — Low-frequency ripple current of 141 mA (120 Hz) and high-frequency ripple current of 211.5 mA (10 kHz), enabling effective smoothing of both line-frequency and switching noise.
• Leakage Current — Specified leakage current of 22 µA, supporting low-standby loss in power-sensitive designs.
• Long Life Endurance — Rated for 5000 hours at 105°C, providing longevity in elevated-temperature environments.
• Wide Temperature Range — Operates from −55°C to +105°C for stable performance across harsh environmental conditions.
• Package & Mounting — Chip-type radial can SMD (φ8 × 10 mm) for surface-mount assembly; supplied in embossed carrier taping for automated placement.
• Quality & Compliance — RoHS compliant and AEC-Q200 qualified, indicating suitability for applications requiring recognized component-level qualification.

Typical Applications

• Automotive Electronics — Bulk decoupling and smoothing in vehicle electronic modules where AEC-Q200 qualification and high-temperature endurance are required.
• Power Supply Filtering — Local energy storage and ripple suppression on DC–DC converter outputs and post-regulator stages, leveraging the capacitor’s HF and LF ripple ratings.
• Embedded Industrial Systems — Power rail stabilization in controllers and sensor hubs operating across −55°C to +105°C.
• Telematics and Infotainment — Supply smoothing and transient buffering for modules exposed to elevated temperatures and variable loads.

Unique Advantages

• High Capacitance in a Small Footprint: 220 µF in a φ8 × 10 mm SMD can conserves PCB area while providing substantial bulk capacitance.
• Designed for Elevated Temperatures: 5000 hours endurance at 105°C supports reliable operation in thermal-stressed environments.
• Balanced Ripple Handling: Specified LF and HF ripple currents allow designers to address both mains-frequency and switching-frequency noise with a single part.
• Predictable Loss and Leakage: Specified tanδ and leakage current values simplify AC loss budgeting and standby current estimates.
• Automotive-Grade Qualification: AEC-Q200 status enables use in applications that require recognized component-level reliability assurance.
• Pick-and-Place Ready Packaging: Embossed carrier taping supports automated assembly and consistent placement for volume production.
