Engineered for automated assembly and production environments, this SMD radial can offers AEC-Q200 qualification and RoHS compliance, making it suitable for automotive and industrial power-filtering and decoupling tasks where reliability across temperature extremes is required.

Key Features

• Electrical Performance — 330 µF capacitance at 6.3 V with ±20% tolerance, providing substantial bulk energy storage for power-rail smoothing and decoupling.
• Wide Temperature Range — Specified to operate from −55°C to +105°C to support applications exposed to extreme ambient conditions.
• Reliability & Lifetime — Endurance rating of 1000 hours at 105°C, with defined limits for capacitance change, tan δ and leakage after the endurance test.
• Ripple Current Capability — Rated ripple currents of 105 mA at 120 Hz and 157.5 mA at 10 kHz to accommodate low- and high-frequency filtering requirements.
• Surface-Mount, Assembly-Ready — Chip-type radial can in an SMD package designed for surface mounting on high-density PCBs and compatible with automatic mounting machines fed with carrier tape.
• Quality & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting automotive-grade and environmentally regulated designs.
• Package & Land Pattern — Radial can SMD package with recommended land size L: 6.6 × W: 6.6 mm for PCB layout.

Typical Applications

• Automotive Control Modules — Bulk filtering and decoupling for power rails in control units that require AEC-Q200 qualified components and wide temperature operation.
• Sensor and Telemetry Electronics — Energy buffering and stabilization for sensor front-ends and data-acquisition circuits operating across extreme temperatures.
• Power-Management Circuits — Output smoothing and decoupling in DC–DC converters and regulator circuits where compact SMD bulk capacitance is required.
• Industrial Embedded Systems — Noise suppression and hold-up capacitance for rugged electronics exposed to thermal cycling and continuous operation.

Unique Advantages
