• Extended High-Temperature Life — Lifetime/Endurance rated to 3000 hours at 125°C, suitable for demanding thermal environments.
• Wide Operating Temperature Range — Specified for operation from −55°C to 125°C to accommodate a broad set of environmental conditions.
• Leakage Current and Loss Angle — Leakage current specified at 125 µA and tan δ (DF) of 0.12 measured at 20°C, 120 Hz.
• SMD Can Package & Tape Packaging — φ10 × 12.4 mm radial can SMD package supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• RoHS Compliant — Conforms to current RoHS requirements.

Typical Applications

• Power supply filtering — Bulk smoothing and filtering in general-purpose power rails where high capacitance and low ESR reduce voltage ripple.
• Decoupling and bulk energy storage — Local energy reservoir for converters and power modules benefiting from the capacitor's high ripple handling and low loss.
• High-frequency power circuits — Circuits operating at higher switching frequencies leveraging the 2.0 A ripple current rating at 300 kHz and low ESR.

Unique Advantages

• Low-loss polymer electrolyte: Conductive polymer construction delivers lower tan δ and ESR compared to higher-loss electrolytes, improving efficiency in power applications.
• High ripple capability: Rated ripple currents of 200 mA (120 Hz) and 2.0 A (300 kHz) enable reliable operation in both low- and high-frequency environments.
• High-temperature endurance: 3000 hours at 125°C provides extended operational life for designs exposed to elevated temperatures.
• Compact SMD can package: φ10 × 12.4 mm form factor in an SMD radial can offers high capacitance density for space-constrained board layouts.
• Manufacturing-ready packaging: Supplied in embossed carrier tape with moisture-proof packing for compatibility with automated assembly and handling processes.
• Designed for reliability: Tight specification of leakage current (125 µA) and controlled loss angle (tan δ = 0.12 at 20°C, 120 Hz) support predictable behavior over life.
