UWZ1H2R2MCL1GB

The UWZ1H2R2MCL1GB is a chip-type aluminum electrolytic capacitor from Nichicon’s UWZ series designed for surface-mount assembly. This part provides 2.2 µF capacitance at a 50 V rating in a compact radial can SMD package (L: 5.4 × D: 4 mm) and is polarized for standard electrolytic use.

Engineered for demanding temperature and production requirements, the UWZ1H2R2MCL1GB supports a wide operating range (−55 to +105°C), is compatible with 260°C peak reflow processes, and is AEC-Q200 qualified and RoHS compliant—making it suitable for automotive electronic applications and automated surface-mount production.

Key Features

• Capacitance & Voltage — 2.2 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Package & Mounting — Chip-type radial can SMD package sized L: 5.4 × D: 4 mm with a recommended surface-mount land size of L: 4.3 × W: 4.3 mm; designed for automatic mounting machine feed with carrier tape.
• Wide Temperature Operation — Rated for −55°C to +105°C operation, supporting harsh ambient conditions.
• High-temperature Reflow Compatibility — Compatible with 260°C peak reflow soldering (recommended: 260°C peak for 5 s; see series reflow guidance for cycle specifics).
• AEC-Q200 Qualified & RoHS Compliant — Meets AEC-Q200 qualification for automotive-grade use and complies with RoHS (2011/65/EU, (EU)2015/863).
• Endurance & Reliability — Rated for 1000 hours at 105°C with specified limits on capacitance change, tan δ, and leakage current after recovery to 20°C.
• Leakage & Loss Characteristics — Leakage current limited to 0.01CV or 3 µA (whichever is greater) after 2 minutes at 20°C; tan δ (max) at 50 V is 0.14 (measured at 120 Hz, 20°C).
• Low-frequency & High-frequency Ripple Current — Specified ripple current: 11 mA at 120 Hz and 16.5 mA at 10 kHz.
• Low-temperature Impedance Stability — Impedance ratios: Z(−25°C)/Z(+20°C) = 2 and Z(−40°C)/Z(+20°C) = 3 for the 50 V rating (measurement at 120 Hz).

Typical Applications

• Automotive electronic modules — Provides decoupling and smoothing on 50 V rails in control modules where AEC-Q200 qualification and wide temperature operation are required.
• Power supply filtering in harsh environments — Suitable for filtering and bypass in systems operating from −55°C to +105°C and exposed to standard reflow assembly processes.
• Automated surface-mount production — Designed for pick-and-place and carrier-tape feeding, easing integration into high-volume manufacturing.

Unique Advantages

• Automotive-grade qualification: AEC-Q200 qualification supports use in automotive electronics and other high-reliability applications.
• 260°C reflow compatibility: Supports high-temperature reflow processes for robust solder joints and modern assembly flows.
• Wide operating temperature: −55°C to +105°C rating enables use across a broad range of environmental conditions.
• Measured electrical characteristics: Specified leakage current limits, tan δ, and ripple current figures allow predictable performance in design margin calculations.
• Compact SMD footprint: Small L × D footprint and defined land pattern simplify board layout for dense designs.
• Proven endurance: 1000 hours at 105°C endurance rating supports long-term reliability planning.
