• Electrical Characteristics  39 µF nominal capacitance with ±20% tolerance, rated at 16 V; tanδ (DF) 0.12 measured at 20 °C, 120 Hz.
• Low ESR & High Ripple Handling  ESR of 31 mΩ measured at 20 °C, 100 kHz; low-frequency ripple current 1.2 A (120 Hz) and high-frequency ripple current 2.4 A (100 kHz).
• Leakage Current  Specified leakage current of 125 µA (after application of rated conditions as defined in the product data).
• Reliability & Qualification  Load life of 2000 hours at 105 °C and AEC-Q200 qualification for use in automotive-grade designs.
• Temperature Range  Operating range −55 °C to +105 °C for broad environmental tolerance.
• Package & Mounting  Compact SMD radial can, size φ6.3 × 5.5 mm (L); recommended land size 6.6 × 6.6 mm for surface-mount assembly.
• Assembly Compatibility  SMD type with lead-free reflow soldering condition support (260 °C peak correspondence, per product specifications) and embossed carrier taping with moisture-proof packing for automated placement.
• RoHS Compliance  Compliant with RoHS directives as stated in the product information.

Typical Applications

• Automotive Power Rails  Bulk decoupling and smoothing on 16 V rails where low ESR and high ripple capability improve voltage stability under dynamic loads.
• In-vehicle Electronics  Power-supply filtering for ECUs and control modules that require AEC-Q200-qualified components and extended high-temperature endurance.
• Power Conversion  Local energy storage and ripple suppression in DC–DC converters and power-supply modules operating across −55 °C to +105 °C.

Unique Advantages

• Low ESR Enables Higher Efficiency:  31 mΩ ESR at 100 kHz reduces conduction losses and supports efficient ripple handling in switching power circuits.
• High Ripple Current Capacity:  Rated ripple currents of 1.2 A (120 Hz) and 2.4 A (100 kHz) allow reliable operation under both low- and high-frequency stress.
• Automotive-Grade Qualification:  AEC-Q200 rating and 2000-hour load life at 105 °C provide proven reliability for automotive and harsh-environment electronics.
• Compact, PCB-friendly Footprint:  φ6.3 × 5.5 mm SMD can with a 6.6 × 6.6 mm recommended land simplifies board layout for space-constrained designs.
• Manufacturing-ready Packaging:  Embossed carrier taping with moisture-proof packing supports high-volume automated assembly and protection during storage.
• Regulatory Compliance:  RoHS compliance aligns the component with environmental and regulatory requirements for commercial and automotive systems.
