UWZ1E4R7MCL1GB

The UWZ1E4R7MCL1GB is a chip-type aluminum electrolytic capacitor from Nichicon's UWZ series designed for surface-mount assembly and automatic tape feeding. It delivers 4.7 µF at 25 V in a compact radial can SMD package and is optimized for applications requiring wide operating temperatures and high-temperature reflow compatibility.

Key value propositions include compatibility with 260°C peak reflow soldering, a broad operating temperature range of –55°C to +105°C, and industry-grade reliability with AEC-Q200 qualification and RoHS compliance.

Key Features

• Capacitance & Voltage: 4.7 µF rated at 25 V with ±20% tolerance (120 Hz, 20°C), suitable for decoupling and smoothing functions within its voltage rating.
• Wide Temperature Range: Specified operation from –55°C to +105°C, with endurance testing defined at 1000 hours at 105°C.
• High-Temperature Reflow Compatibility: Corresponds with 260°C peak reflow soldering; recommended reflow condition is 260°C peak for 5 seconds and 230°C over 60 seconds (2 times; exceptions noted for larger diameters).
• AEC-Q200 Qualified: Meets AEC-Q200 qualification as stated in the product data, supporting use in environments requiring component-level reliability validation.
• Surface-Mount Radial Can Package: Compact dimensions L: 5.4 × D: 4 mm in a radial, can-style SMD package with surface mount land size L: 4.3 × W: 4.3 mm, compatible with automatic mounting machines fed with carrier tape.
• Endurance & Leakage: Endurance: 1000 hours at 105°C with capacitance change within ±20% (for rated voltages ≥20 V); leakage current specified as not more than 0.01CV or 3 µA (whichever is greater).
• Ripple Current Ratings: Low-frequency ripple current 13 mA at 120 Hz and high-frequency ripple current 19.5 mA at 10 kHz for design margining.
• RoHS Compliant: Conforms to the RoHS directive (2011/65/EU and (EU)2015/863).

Typical Applications

• Automotive electronics: Use in vehicle electronics where AEC-Q200 qualification, wide temperature range (–55°C to +105°C), and long endurance (1000 h at 105°C) are required.
• Power supply decoupling: Smoothing and local decoupling in power rails within 25 V systems, leveraging the part's 4.7 µF capacitance and specified ripple current ratings.
• Compact SMD assemblies: Surface-mount radial can footprint suited to automated placement with carrier tape for high-volume manufacturing environments.

Unique Advantages

• High-temperature reflow tolerance: Validated for 260°C peak reflow conditions, enabling compatibility with lead-free, high-temperature assembly processes.
• Automotive-grade reliability: AEC-Q200 qualification and defined endurance at 105°C provide traceable performance expectations for demanding applications.
• Wide operating temperature window: –55°C to +105°C operation allows deployment across harsh temperature environments without changing capacitor selection.
• Compact SMD form factor: Small L: 5.4 × D: 4 mm package and defined land pattern support space-constrained board designs and automated assembly.
• Regulated leakage and endurance: Clear leakage current limits (0.01CV or 3 µA) and endurance caps simplify margining in power and timing circuits.
• Standards compliance: RoHS conformity supports regulatory requirements for restricted substances.
