Key Features

• Core Technology  Conductive polymer aluminum solid electrolyte in a chip (SMD) can package for stable capacitance and low loss.
• Electrical  39 µF capacitance at 50 V with a tolerance of ±20%; polarized device suitable for DC smoothing and decoupling.
• Low ESR & High Ripple Handling  ESR of 45 mΩ at 100 kHz and rated ripple currents of 1.6 A (100 kHz) and 800 mA (120 Hz) to support high-frequency power delivery.
• High-Temperature Performance  Rated operating range −55 °C to +125 °C and long-life specification of 8000 hours at 125 °C for sustained high-temperature use.
• Reliability & Qualification  AEC‑Q200 qualified with endurance and damp‑heat characteristics defined by the datasheet; ESR specified after endurance at −40 °C.
• Assembly Compatibility  SMD type designed for lead‑free reflow soldering with a 260 °C peak reflow profile (pre‑heat and time‑above‑230 °C requirements per datasheet).
• Package & Footprint  Radial can SMD package, nominal body size L: 7 × D: 8 mm with recommended land size 8.3 × 8.3 mm.
• Regulatory Compliance  Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics  Designed for use in automotive power and control modules where AEC‑Q200 qualification, wide temperature range and long life are required.
• SMD power filtering  Surface‑mount power decoupling and smoothing on high‑density boards that require low ESR and high ripple current capability.
• High-temperature assemblies  Suitable for assemblies requiring lead‑free reflow up to a 260 °C peak while maintaining specified capacitance and ESR limits.

Unique Advantages

• Long high-temperature lifetime:  8000 hours at 125 °C provides predictable endurance for elevated-temperature systems.
• Low ESR for improved power integrity:  45 mΩ at 100 kHz reduces voltage drop and heat generation in high-frequency power paths.
• High ripple-current capability:  1.6 A at 100 kHz and 800 mA at 120 Hz support demanding transient and continuous ripple loads.
• AEC‑Q200 qualification:  Specifies suitability for automotive and other high-reliability applications requiring industry qualification.
• Reflow-ready SMD can:  Lead‑free reflow compatibility to 260 °C simplifies assembly in modern surface‑mount production flows.
• RoHS compliant:  Meets current RoHS requirements for environmental compliance.
