Key value includes high ripple handling, long endurance at elevated temperature, and RoHS compliance.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 10 V with ±20% tolerance (120 Hz, 20 °C).
• Wide Temperature Range — Specified operating range of ‑55 °C to +105 °C for reliable performance across extreme environments.
• AEC‑Q200 Qualified — Engineered and qualified for automotive applications per the AEC‑Q200 rating.
• Endurance — Rated lifetime of 2000 hours at 105 °C under rated voltage; capacitance change and other endurance characteristics are specified after this test.
• Ripple Current Capability — 250 mA at 120 Hz (low frequency) and 375 mA at 100 kHz (high frequency) for effective ripple handling in power circuits.
• Compact SMD Can Package — Radial, can‑style SMD (chip type) with physical size approximately 10 mm × 8 mm and recommended land pattern 8.3 mm × 8.3 mm for PCB layout.
• Surface‑Mount Assembly Ready — Designed for automatic mounting using carrier tape to support high‑volume SMT processes.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Polarized — Designed as a polarized electrolytic capacitor; observe polarity during assembly.

Typical Applications

• Automotive Electronics — AEC‑Q200 qualification and wide temperature range make this capacitor suitable for automotive control modules and in‑vehicle electronics.
• Audio Equipment — Part of Nichicon's chip‑type acoustic series intended for audio use, suitable for audio power supply and signal coupling where compact SMD parts are required.
• High‑Temperature Systems — Endurance rating of 2000 hours at 105 °C supports use in assemblies exposed to sustained elevated temperatures.
• High‑throughput SMT Production — Carrier‑tape compatibility enables reliable placement in automatic mounting lines for volume manufacturing.

Unique Advantages

• Automotive‑grade qualification: AEC‑Q200 status provides traceable qualification for automotive designs and other demanding applications.
• Wide operational temperature: Rated from ‑55 °C to +105 °C, supporting designs subject to extreme thermal conditions.
