Key Features

• Dielectric / Construction  Conductive polymer aluminum solid electrolytic, chip type in a surface-mount radial can package for compact board-level power solutions.
• Capacitance & Voltage  470 µF nominal capacitance with ±20% tolerance and a rated voltage of 16 V.
• Low Loss / Low ESR  Tangent of loss angle (tan δ) of 0.08 (measured at 20 °C, 120 Hz) and ESR of 17 mΩ measured at 20 °C / 100 kHz for improved power efficiency and thermal performance.
• High Ripple Current Capability  Low-frequency ripple current 1.2 A (120 Hz) and high-frequency ripple current 2.4 A (100 kHz) to handle dynamic load conditions.
• Leakage Current  Specified leakage current of 225 µA after rated voltage application, suitable for controlled bias and hold-up requirements.
• Robust Endurance  Rated for 4000 hours at 135 °C with defined limits on capacitance change, tan δ, ESR and leakage after endurance testing.
• Automotive-Grade Qualification  AEC-Q200 qualified for use in automotive electronic modules.
• SMD Assembly Compatibility  SMD type with lead-free reflow compatibility (peak soldering profile correspondence up to 260 °C) and supplied in embossed carrier taping with moisture-proof packing.
• Wide Temperature Range  Operational from −55 °C to +135 °C for high-temperature system environments.
• RoHS Compliance  Compliant with RoHS requirements.

Typical Applications

• Automotive Electronics  Suited for in-vehicle power modules and electronic control units where AEC-Q200 qualification and operation to 135 °C are required.
• Power Supply Filtering  Use on DC–DC converter outputs and regulator rails that demand high ripple current handling and low ESR for stable voltage regulation.
• High‑Temperature Systems  Ideal for electronic assemblies that operate across a broad temperature range (−55 °C to 135 °C) and require long endurance at elevated temperatures.

Unique Advantages

• High ripple tolerance: Low-frequency and high-frequency ripple current ratings (1.2 A at 120 Hz / 2.4 A at 100 kHz) help maintain performance under dynamic loads.
• Low series resistance: ESR of 17 mΩ at 100 kHz reduces power loss and heat generation in power delivery applications.
• Temperature and endurance resilience: Rated for 4000 hours at 135 °C with controlled changes in capacitance, tan δ and ESR, supporting long-term reliability in harsh environments.
• Automotive readiness: AEC-Q200 qualification provides an explicit reliability baseline for automotive subsystem designers.
• SMD supply and assembly-ready: Provided in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow profiles for standard surface-mount manufacturing.
• Measured performance transparency: Key measured specifications (tan δ, ESR, leakage) are defined under stated conditions for straightforward design validation.
