UWZ1C470MCL1GB

The UWZ1C470MCL1GB is a chip‑type aluminum electrolytic surface‑mount capacitor from Nichicon’s UWZ series. It delivers 47 µF at 16 V in a compact radial can SMD package designed for automatic tape feeding and pick‑and‑place assembly.

Engineered for wide operating temperatures (−55 °C to +105 °C) and high‑temperature reflow compatibility (260 °C peak), this part targets demanding electronics designs—including automotive applications—where temperature resilience, long life, and industry qualification matter.

Key Features

• Core Architecture: Chip‑type aluminum electrolytic capacitor providing 47 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C.
• Rated Voltage: 16 V DC rating suitable for low‑voltage power rails and decoupling tasks.
• Wide Temperature Range: Operates from −55 °C to +105 °C, supporting designs exposed to broad thermal environments.
• High‑Temperature Reflow Compatibility: Designed to withstand 260 °C peak reflow; recommended profile: 260 °C peak for 5 seconds, 230 °C over 60 seconds, two cycles (some sizes single cycle as specified).
• Reliability & Lifetime: Endurance specified as 1000 hours at 105 °C with capacitance change within ±25% for 16 V parts and leakage/tan δ limits per datasheet.
• Ripple Performance: Rated ripple current: 50 mA at 120 Hz and 75 mA at 10 kHz, supporting smoothing and decoupling in switching environments.
• Package & Mounting: Radial can SMD (chip type) with nominal size L: 5.4 × D: 6.3 mm and recommended PCB land size 6.6 × 6.6 mm for surface‑mount assembly.
• Compliance & Qualification: RoHS compliant and AEC‑Q200 qualified for applications that require automotive‑grade component qualification.

Typical Applications

• Automotive Electronics: Bulk decoupling and smoothing on control modules and power rails where AEC‑Q200 qualification and wide temperature operation are required.
• Power Supply Filtering: Local energy storage and ripple suppression on DC‑DC converters and regulator outputs in compact board layouts.
• Embedded Control Modules: Decoupling for microcontroller power domains and analog front ends that need stable capacitance across −55 °C to +105 °C.

Unique Advantages

• High‑temperature assembly compatibility: 260 °C peak reflow rating enables use with modern lead‑free reflow processes without special handling.
• Automotive qualification: AEC‑Q200 status provides a clear qualification path for vehicle electronics and related high‑reliability systems.
• Wide operating temperature: −55 °C to +105 °C range maintains electrical performance across harsh thermal conditions.
• Long endurance at elevated temperature: 1000 hours at 105 °C validates expected lifetime performance for sustained high‑temperature applications.
• Compact SMD can package: Small footprint (5.4 × 6.3 mm) and tape‑feed compatibility simplify automated assembly and dense PCB designs.
• Regulatory compliance: RoHS compliance supports restricted‑substance requirements for commercial and industrial programs.
