UWD0J470MCL1GS

The UWD0J470MCL1GS is a 47 µF, 6.3 V chip-type aluminum electrolytic capacitor engineered for surface-mount use on high-density PCBs. It combines a low-impedance construction with compatibility for high-temperature reflow processes and qualification for AEC‑Q200, making it suitable for demanding automotive and industrial electronics.

Key value comes from its high-temperature endurance (operation to +105°C and rated lifetime at elevated temperature), robust reflow tolerance to 260°C peak, and compact SMD can package optimized for automated placement.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 6.3 V rated voltage and a capacitance tolerance of ±20% at 120 Hz, 20°C.
• Low Impedance Performance — Series-design low impedance with a specified impedance of 760 mΩ, suitable for decoupling and local energy storage in power circuits.
• High-Temperature Operation — Rated for operation from −55°C to +105°C, with endurance specified at 2000 hours at 105°C for this case size.
• High-Temperature Reflow Compatibility — Designed to withstand 260°C peak reflow soldering; recommended reflow profile: 260°C peak for 5 seconds and 230°C for over 60 seconds (cycle repeatability noted in series data).
• Ripple Current Ratings — Specified ripple handling of 75 mA at 120 Hz and 150 mA at 10 kHz for typical board-level filtering applications.
• Surface-Mount Can Package — Compact radial can SMD package with dimensions L: 5.8 × D: 5.0 mm and recommended land pattern of 5.3 × 5.3 mm for automated tape-and-reel placement.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant, with series-level endurance, leakage and tan δ limits defined in the datasheet.

Typical Applications

• Automotive Power Filtering — Local decoupling and smoothing for ECU power rails where AEC‑Q200 qualification and elevated temperature endurance are required.
• DC‑DC Converter Output — Low-impedance bulk capacitance for output filtering in compact power modules operating up to +105°C.
• Sensor and Control Modules — Energy storage and noise suppression in automotive and industrial sensors and control boards exposed to wide temperature ranges.

Unique Advantages

• Reflow-ready construction: Specified for 260°C peak reflow profiles, enabling streamlined surface-mount assembly on high-density boards.
• Automotive-grade qualification: AEC‑Q200 rating provides documented reliability expectations for automotive and other high-reliability applications.
• Compact SMD can: Small L: 5.8 × D: 5.0 mm package and recommended 5.3 × 5.3 mm land pattern reduce board area while supporting automated placement.
• High-temperature endurance: Rated for continuous operation to +105°C with a specified lifetime of 2000 hours at that temperature for this case size.
• Clear electrical limits: Defined impedance (760 mΩ), ripple current ratings, leakage current and tan δ limits from the series datasheet make design margining straightforward.
