Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 25 V with a tolerance of ±20% for bulk energy storage and decoupling in compact boards.
• Temperature Range & Endurance — Rated for −40 °C to 125 °C with an endurance specification of 2000 hours at 125 °C, suitable for sustained high‑temperature operation.
• Low‑temperature ESR Performance — Includes an added ESR specification after the −40 °C test and an equivalent series resistance of 200 mΩ measured at 100 kHz, enabling predictable impedance at cold temperatures.
• Ripple Current Rating — Defined ripple performance: 135 mA at 120 Hz and 270 mA at 10 kHz to support varying frequency power conditions.
• SMD Packaging & Assembly — Chip/can SMD package designed for automatic mounting with carrier tape; recommended PCB land size 8.3 × 8.3 mm for reliable placement.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant; leakage current specification ≤0.01CV (µA) after 2 minutes at 20 °C per datasheet guidance.

Typical Applications

• Automotive electronics — AEC‑Q200 qualification and −40 °C to 125 °C rating make this capacitor suitable for in‑vehicle electronic systems that require high reliability.
• High‑temperature electronic assemblies — Endurance of 2000 hours at 125 °C supports applications exposed to prolonged elevated temperatures.
• Automated SMD production — Carrier‑tape compatibility and defined SMD land size facilitate pick‑and‑place assembly in high‑volume manufacturing.

Unique Advantages

• AEC‑Q200 qualified: Provides documented high‑reliability performance for demanding environments where qualification matters.
