• High Ripple-Current Capability: Rated low-frequency ripple current of 1.9805 A (120 Hz) and high-frequency ripple current of 2.33 A (10 kHz), supporting switching converter and regulator applications.
• Loss and Leakage: Loss tangent (tanδ/DF) specified at 0.2 (measured 20 °C, 120 Hz) and a measured leakage current of 1,584 µA for predictable performance in biased applications.
• Reliability & Endurance: Designed for 5,000 hours of life at 105 °C, with a rated operating temperature range from −55 °C to 105 °C.
• Mechanical & Mounting: Radial lead, can-style package (φ16 × 20 mm) with 7.5 mm lead spacing (±0.5 mm) for straightforward through-hole assembly.
• Packaging & Production Status: Available in bulk or bag packing and is in mass production; RoHS compliant for environmental conformity.

Typical Applications

• Switching Power Supplies: Provides bulk energy storage and ripple smoothing for DC output stages in switching regulators.
• DC‑DC Converters: Used for input/output filtering and transient suppression where compact, high-capacitance components are required.
• Power Filtering & Decoupling: Ideal for board-level power filtering to stabilize rails and reduce noise in general-purpose electronic systems.
• Industrial Control Electronics: Suited to control boards and power modules that require durable capacitors with long life at elevated temperatures.

Unique Advantages

• High ripple handling: 1.98 A (120 Hz) and 2.33 A (10 kHz) ripple ratings reduce capacitor stress in switching environments and extend usable life in high-activity circuits.
• Low impedance: 52 mΩ impedance supports improved transient response and lower voltage drop under load compared with higher-impedance alternatives.
• Long endurance at elevated temperature: 5,000-hour lifetime at 105 °C provides predictable aging behavior and reliability for sustained thermal environments.
• Compact radial-can footprint: φ16 × 20 mm size with 7.5 mm lead spacing delivers high capacitance density for space-constrained through-hole designs.
• Designed for practical assembly: Radial leads and standard lead spacing simplify placement and soldering in conventional PCB assembly workflows.
• RoHS compliant and production-ready: Environmentally compliant and available in bulk/bag pack quantities for production deployment.
