• Endurance: Rated for 2000 hours at 85°C with capacitance change within ±20% after test, per datasheet endurance conditions.
• Leakage Current Spec: Leakage current after 1 minute at rated voltage is ≤ 0.03CV (µA), enabling predictable leakage behavior.
• Dissipation Factor (tan δ): Low loss characteristics with tan δ ≤ 0.12 at 63 V (measured at 120 Hz, 20°C).
• Ripple Current Capability: Specified ripple current of 140 mA at 120 Hz and 233.8 mA at 10 kHz for AC superposition considerations.
• RoHS and AEC‑Q200 Compliance: RoHS compliant and AEC‑Q200 rated to meet applicable regulatory and automotive reliability expectations.
• Tolerance: ±20% capacitance tolerance at 120 Hz, 20°C.

Typical Applications

• Automotive electronic modules: Bulk filtering and decoupling in vehicle control units and electronic modules where AEC‑Q200 qualification is required.
• High‑density PCB assemblies: Surface‑mount form factor supports compact board layouts and automated carrier‑tape assembly.
• Power supply smoothing: Board‑level energy storage for DC‑DC converters and voltage rails requiring polarized electrolytic capacitance.

Unique Advantages

• High capacitance in an SMD chip: 47 µF provides significant bulk capacitance while keeping a small board footprint for dense designs.
• Automated assembly ready: Carrier‑tape compatible chip type simplifies pick‑and‑place and reflow processes for volume production.
• Automotive‑grade reliability: AEC‑Q200 compliance supports use in automotive environments that demand component qualification.
• Predictable endurance: 2000 hours at 85°C endurance specification gives designers a clear expectation of long‑term behavior under elevated temperature stress.
• Measured electrical characteristics: Specified leakage, tan δ, and ripple current values enable more accurate power‑stage and thermal design margins.
• Regulatory compliance: RoHS status simplifies environmental compliance for assemblies and systems.
