Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance, providing bulk energy storage and decoupling for power rails.
• High-temperature endurance — Rated for 5000 hours at +105°C with the rated voltage applied; capacitance change is within ±30% after endurance testing as specified.
• AEC-Q200 Qualified — Manufacturing and qualification per AEC-Q200 for automotive-grade reliability and consistency.
• Wide operating range — Specified for −40°C to +105°C operation, with defined impedance stability at low temperatures (impedance ratios provided for −25°C and −40°C vs +20°C).
• Leakage and loss characteristics — Leakage current limit defined as 0.01 CV or 3 µA (whichever is greater) after 2 minutes at 20°C; tangent of loss angle (tan δ) specified for the 25 V rating (max. 0.16 at 120 Hz, 20°C).
• Ripple current capability — Rated ripple current of 238 mA at 120 Hz and 357 mA at 10 kHz to support AC loading and filtering needs.
• Surface-mount radial can package — Compact 1.0 × 1.0 cm size (L × D) with recommended land size 1.03 × 1.03 cm, designed for placement on high-density PCBs; case marked with black print on the top.
• Soldering robustness and shelf life — Resistance to soldering heat specified (250°C, 30 s on hot plate) with capacitance change within ±10%; shelf-life recovery procedures and performance after 1000 h at 105°C are defined.
• Environmental compliance — Compliant to the RoHS directive (2011/65/EU and (EU)2015/863).

Typical Applications

• Automotive electronics — Power rail smoothing and decoupling in control modules and power subsystems where AEC-Q200 qualification and +105°C endurance are required.
• High-density PCB designs — Compact SMD radial-can package for systems that demand substantial capacitance in a small board footprint.
• Industrial and embedded systems — Bulk energy storage and filtering in applications operating across −40°C to +105°C ambient ranges.

Unique Advantages

• Long high-temperature life: 5000 hours at +105°C provides predictable long-term performance under sustained elevated-temperature conditions.
• Automotive-grade qualification: AEC-Q200 qualification supports use in automotive and other demanding reliability environments.
• Compact SMD form factor: 1.0 × 1.0 cm package and 1.03 × 1.03 cm recommended land pattern enable high-density board layouts without sacrificing capacitance.
• Clear electrical limits: Defined leakage current, tan δ, and ripple current specifications allow straightforward thermal and electrical design margins.
• Soldering and shelf robustness: Specified resistance to soldering heat and shelf-life recovery procedures simplify board assembly and storage planning.
• Regulatory compliance: RoHS compliance supports use in products requiring restricted-substance conformance.
