Key Features

• Capacitance & Voltage: 560 µF nominal capacitance with a rated voltage of 63 V and tolerance of −20% to +20%.
• Temperature Range & Endurance: Rated for −40 °C to 125 °C with an endurance specification of 4000 hours at 125 °C for the φ16 × 21.5L case size.
• Low‑Temperature ESR Specification: ESR specified after −40 °C testing; measured ESR is 70 mΩ at 20 °C and 100 kHz.
• Ripple Current Capability: Low frequency ripple current 1.25 A at 120 Hz and high frequency ripple current 2.5 A at 10 kHz, supporting power filtering and decoupling under dynamic loads.
• Loss and Leakage: Tangent of loss angle (tanδ) 0.12 measured at 20 °C, 120 Hz, and measured leakage current of 352.8 µA.
• Package & Mounting: φ16 × 21.5 mm radial can in SMD form factor with embossed carrier taping for automated surface‑mount assembly; recommended land size L: 1.63 × W: 1.63 cm.
• Qualification & Compliance: AEC‑Q200 qualified and RoHS compliant for use in regulated environments.

Typical Applications

• Automotive power systems: AEC‑Q200 qualification, wide operating temperature range (−40 °C to 125 °C) and 4000 h endurance at 125 °C make this capacitor suitable for automotive electronic modules requiring sustained high‑temperature performance.
• High‑temperature electronics: Designed for +125 °C use with explicit endurance data, providing a reliable option where elevated ambient or component temperatures are expected.
• Surface‑mount power filtering: High ripple current ratings (1.25 A @120 Hz, 2.5 A @10 kHz) and low ESR (70 mΩ @100 kHz) support smoothing and decoupling in compact SMD power designs.

Unique Advantages

• High‑temperature endurance: 4000 hours rated life at 125 °C for the φ16 × 21.5L case provides predictable long‑term behavior in hot environments.
• Automotive‑grade qualification: AEC‑Q200 qualification offers a documented reliability baseline for automotive and demanding commercial applications.
• Robust ripple handling: Specified low‑ and high‑frequency ripple currents enable effective smoothing under both mains and switching converter noise conditions.
• Low ESR at high frequency: 70 mΩ measured at 100 kHz reduces losses and heating in high‑frequency power paths.
• Surface‑mount automation ready: Embossed carrier taping and SMD can package support automated pick‑and‑place assembly for volume production.
• Measured loss performance: tanδ of 0.12 at 20 °C/120 Hz provides a quantified dissipation characteristic for design tradeoffs.
