• Temperature Range: Rated for operation from −40°C to +125°C.
• Endurance / Reliability: Life rating of 2000 hours at 125°C with specified limits for capacitance change, tan δ, and leakage current after test.
• AEC-Q200 Qualified: Meeting AEC-Q200 requirements for use in automotive applications (qualification noted in product data).
• Low-frequency and High-frequency Ripple Handling: Rated ripple currents of 250 mA at 120 Hz and 500 mA at 10 kHz to support smoothing and decoupling duties.
• Electrical Losses: ESR of 150 mΩ measured at 20°C/100 kHz and tan δ up to 0.18 at 20°C/120 Hz (for 25 V rating), enabling predictable loss and heating behavior.
• Leakage Current: Specified leakage current of 140 µA.
• Package & Assembly: Chip (can-type) SMD, φ10×10 mm, vibration resistant and supplied in embossed carrier taping for automatic mounting machines.
• Regulatory Compliance: RoHS compliant as listed in product data.

Typical Applications

• Automotive power modules: Bulk smoothing and decoupling in control units, leveraging AEC-Q200 qualification and 125°C endurance.
• DC–DC converters: Output filtering and energy storage where high ripple handling and low ESR at switching frequencies are required.
• Industrial electronics: Power rails and converter stages in rugged environments that demand wide temperature operation and vibration resistance.

Unique Advantages

• AEC-Q200 qualification: Enables use in automotive-class designs where component-level qualification is required.
• High-temperature endurance: Rated for 2000 hours at 125°C, providing long-term stability in hot operating conditions.
• Frequency-capable ripple performance: Separate ripple specifications at 120 Hz and 10 kHz (250 mA and 500 mA respectively) for low- and high-frequency power stages.
• Predictable ESR and loss characteristics: ESR specified at 150 mΩ (20°C/100 kHz) and tan δ defined at 120 Hz for design-level thermal and loss calculations.
• SMD can in embossed tape: φ10×10 mm chip form factor with embossed carrier taping supports automated pick-and-place and reflow assembly processes.
• Wide operating temperature: −40°C to +125°C usability for applications across harsh and temperature-variable environments.
