Key Features

• Dielectric and Construction — Conductive polymer aluminum solid electrolyte in a chip (radial can SMD) package for stable capacitance and long-life operation.
• Capacitance & Tolerance — 39 µF nominal with ±20% tolerance at 120 Hz, 20°C.
• Voltage Rating — Rated for 16 V DC operation.
• Temperature Range & Endurance — Rated for −55°C to +105°C with a specified load life of 5000 hours at 105°C; meets endurance recovery requirements after test conditions.
• Low ESR and Ripple Handling — ESR of 30 mΩ at 100 kHz; ripple current ratings of 1.1 A at 120 Hz and 2.2 A at 100 kHz support power filtering and decoupling at both low and high frequencies.
• Soldering and Assembly — SMD type compatible with lead-free reflow soldering up to a 260°C peak (single reflow at ≤260°C); designed for standard pre-heat and reflow profiles as specified.
• Reliability & Qualification — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863); damp-heat and soldering-heat endurance data available per datasheet.
• Package & Footprint — Compact dimensions (L: 6 × D: 6.3 mm) with a recommended land pattern of 6.6 × 6.6 mm and a seated height up to 6 mm.

Typical Applications

• Automotive power electronics — Bulk decoupling and local energy storage on vehicle power rails where AEC-Q200 qualification and 105°C endurance are required.
• Electronic control modules — Stability and ripple suppression for control and driver circuits that demand low ESR and long life under elevated temperatures.
• Sensor and actuator circuits — Local filtering and transient support in automotive sensing and actuation systems benefiting from low ESR and high-frequency ripple capability.

Unique Advantages

• Long-term high-temperature endurance — Rated for 5000 hours at 105°C, helping maintain capacitance and performance in elevated-temperature environments.
• AEC-Q200 qualification — Designed to meet automotive component quality requirements for use in vehicle electronics.
• Low ESR for improved efficiency — 30 mΩ ESR at 100 kHz reduces I²R losses and improves filtering performance at high frequencies.
• High ripple capability — Ripple current ratings (1.1 A at 120 Hz, 2.2 A at 100 kHz) support both low‑ and high‑frequency power conditioning tasks.
• Lead-free reflow ready — Compatible with lead-free assembly processes up to a 260°C peak, easing integration into modern manufacturing flows.
• Compact SMD radial-can package — Small footprint (6 × 6.3 mm) and defined land pattern simplify PCB layout for space-constrained designs.
