UWZ1A101MCL1GB

The UWZ1A101MCL1GB is a chip-type aluminum electrolytic capacitor designed for surface-mount production and demanding operating environments. It delivers 100 µF at 10 V in a compact SMD can package and is built for wide operating temperatures and automated assembly.

Key attributes include compatibility with 260°C peak reflow soldering, a broad operating temperature range from −55°C to +105°C, AEC-Q200 qualification, and RoHS compliance—making it suitable for automotive and other reliability-focused electronic systems.

Key Features

• Electrical Performance — 100 µF rated capacitance at 10 V with ±20% tolerance (measured at 120 Hz, 20°C). Polarized device suitable for power decoupling and smoothing in SMD designs.
• Wide Temperature Range & Endurance — Category temperature range −55°C to +105°C with an endurance specification of 1000 hours at 105°C under rated voltage.
• High-Temperature Reflow Compatibility — Corresponds with 260°C peak reflow soldering. Recommended reflow condition: 260°C peak for 5 s; 230°C for over 60 s two times (exceptions noted for larger diameters in the series).
• Automotive-Grade Reliability — AEC-Q200 qualified, supporting use in automotive electronic applications that require recognized component-level qualification.
• Assembly-Friendly Package — Chip-type, radial can SMD package designed for automatic mounting machines fed with carrier tape; surface-mount land size 6.6 × 6.6 mm.
• Frequency & Ripple Performance — Ripple current ratings of 60 mA at 120 Hz and 90 mA at 100 kHz, suitable for filtering and decoupling across low and higher frequency domains.
• Leakage & Loss Characteristics — Leakage current after 2 minutes at 20°C is not more than 0.01CV or 3 µA (whichever is greater). Tangent of loss angle (tan δ) for 10 V is specified with a maximum of 0.24.
• Low-Temperature Stability — Impedance stability specified against 20°C: for 10 V parts Z(−25°C)/Z(+20°C) ≤ 3 and Z(−40°C)/Z(+20°C) ≤ 8, supporting operation in cold environments.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and −55°C to +105°C temperature range support usage in automotive control modules, infotainment power rails, and other on-vehicle electronics.
• Surface-Mount Power Modules — Compact chip can package and defined surface-mount land pattern make this capacitor suitable for space-constrained power supply boards where automated assembly is used.
• Power Filtering & Decoupling — 100 µF capacitance with specified ripple current ratings provides bulk filtering and decoupling for low-voltage power rails in embedded systems.

Unique Advantages

• 260°C Reflow Compatibility: Enables robust assembly processes using high-temperature peak profiles without degrading capacitor characteristics when reflow recommendations are followed.
• Wide Operating Temperature Band: −55°C to +105°C rating extends usable range across harsh thermal environments, reducing the need for multiple capacitor variants.
• Automotive Qualification: AEC-Q200 qualification supports designs targeting automotive markets and other high-reliability sectors.
• Long Endurance at Elevated Temperature: Specified 1000-hour life at 105°C under rated voltage provides predictable long-term behavior in hot operating conditions.
• Automated Assembly Ready: Chip-type SMD can format and carrier-tape compatibility streamline pick-and-place manufacturing for high-volume production.
• Verified Low-Temperature and Frequency Behavior: Documented impedance ratios and ripple ratings give designers measurable performance across temperature and frequency ranges.
