Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 16 V, suitable for bulk smoothing and local energy storage on power rails.
• Low Impedance — Specified impedance of 150 mΩ to support effective decoupling and reduce voltage ripple in high-demand circuits.
• Ripple Current Handling — Rated ripple current of 335 mA at 120 Hz and 670 mA at 10 kHz for improved performance under AC load conditions.
• Wide Temperature Range — Operates from −55 °C to +105 °C, enabling use in harsh thermal environments.
• High-Temperature Endurance — 1000 hours rated lifetime at 105 °C, with capacitance and leakage performance specified after endurance testing.
• Surface-Mount, Tape-Feed Compatible — Chip-type radial can SMD package designed for surface mounting on high-density PCBs and compatible with automatic mounting machines fed by carrier tape.
• Tolerance & Polarity — Capacitance tolerance ±20% and polarized construction for correct orientation in DC circuits.
• Compliance & Qualification — AEC-Q200 qualified and RoHS (2011/65/EU, (EU)2015/863) compliant.
• Compact Footprint — Size dimensions L: 1 × D: 1 cm with recommended surface-mount land size L: 1.03 × W: 1.03 cm for PCB layout.

Typical Applications

• Automotive Power Modules — Use as bulk and decoupling capacitance on power rails where AEC-Q200 qualification and −55 °C to +105 °C operation are required.
• Power Supply Filtering — Local energy storage and ripple suppression for DC/DC converters and voltage regulators, leveraging low impedance and rated ripple currents.
• Industrial Electronics — Bulk smoothing and transient support in industrial control and monitoring equipment exposed to wide temperature ranges.
• High-Density PCB Designs — Surface-mount, tape-feed compatible package suited to automated assembly on compact boards.
