• High Ripple Capability — 200 mA low-frequency ripple (120 Hz) and 2 A high-frequency ripple (300 kHz) ratings for demanding power-supply smoothing and switching applications.
• Wide Temperature Range & Endurance — Operating range −55°C to +125°C with a rated life of 3000 hours at 125°C for long-term reliability in elevated-temperature environments.
• SMD Can Package & Assembly Compatible — φ10 × 10 mm radial can in an SMD configuration, supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering up to a 260°C peak per datasheet guidance.
• Loss Tangent — tan δ (loss angle) of 0.12 at 20°C, 120 Hz for predictable AC performance.
• RoHS Compliant — Meets RoHS directive requirements as stated in the product data.

Typical Applications

• General Purpose Power Filtering — Surface-mount 68 µF, 25 V capacitor for bulk decoupling and smoothing in general-purpose electronic circuits.
• High-Frequency Power Rails — Low ESR (20 mΩ) and 2 A HF ripple rating support smoothing and transient handling on switching converter outputs and power modules.
• Elevated-Temperature Electronics — Rated for −55°C to +125°C and 3000 hours at 125°C, suitable for applications that require sustained performance under higher ambient temperatures.

Unique Advantages

• Validated High-Temperature Endurance: 3000 hours at 125°C provides documented lifecycle performance for designs exposed to prolonged elevated temperatures.
• Superior High-Frequency Behavior: 20 mΩ ESR at 100 kHz and a 2 A HF ripple rating reduce voltage ripple and thermal stress in switching applications.
• Compact SMD Can: φ10 × 10 mm SMD can package balances capacitance density with board-space efficiency and is supplied in embossed carrier taping for automated assembly.
• Predictable Leakage and Loss Characteristics: Specified leakage current (100 µA) and tan δ (0.12 at 120 Hz) enable reliable design margins for leakage and dissipation budgeting.
• Assembly-Friendly: Compatible with lead-free reflow soldering profiles up to 260°C peak as specified in the datasheet, supporting modern manufacturing flows.
• Regulatory Compliance: RoHS compliance simplifies environmental qualification for global product distribution.
