UWZ1H4R7MCL1GB

The UWZ1H4R7MCL1GB is a chip-type aluminum electrolytic capacitor from Nichicon’s UWZ series designed for surface-mount assembly. It delivers 4.7 µF capacitance at a 50 V rating in a compact radial-can SMD package suitable for automated tape-fed placement.

Built for demanding environments, the part supports a wide operating temperature range from −55°C to +105°C, is AEC-Q200 qualified, and is compliant with RoHS (2011/65/EU, (EU)2015/863), offering robust performance and industry-standard environmental compliance for automotive and industrial electronics.

Key Features

• Electrical Specification — Rated capacitance 4.7 µF and rated voltage 50 V, with capacitance tolerance of −20% to +20% at 120 Hz, 20°C.
• Wide Temperature Range — Operates from −55°C to +105°C, enabling use across extreme-temperature applications.
• High-temperature Reflow Compatibility — Engineered for 260°C peak reflow soldering; recommended reflow condition: 260°C peak for 5 s and 230°C over 60 s (process guidance noted in datasheet).
• Automotive-Grade Reliability — AEC-Q200 qualified for designs requiring automotive-level component qualification.
• Endurance — Rated for 1000 hours at 105°C under rated voltage, with specified limits for capacitance change, tan δ, and leakage current after endurance testing.
• Compact SMD Package — Radial can SMD package with dimensions L: 5.4 × D: 5.0 mm and surface-mount land size L: 5.3 × W: 5.3 mm, suitable for automated placement.
• Leakage Current Specification — Series leakage definition: after 2 minutes’ application of rated voltage at 20°C, leakage current ≤ 0.01CV or 3 µA (whichever is greater), per datasheet guidance.
• RoHS Compliant — Meets applicable RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive control modules — Power supply decoupling and smoothing in engine control units, body electronics, and other modules that require AEC-Q200 qualified components and wide temperature operation.
• Power conversion and regulation — Bulk and output filtering in DC–DC converters and on-board power supplies where compact SMD capacitors with verified endurance are required.
• Sensor and actuator electronics — Stabilizing supply rails for sensors and actuators exposed to broad temperature extremes.

Unique Advantages

• High-temperature assembly compatibility: Supports 260°C peak reflow, simplifying integration into high-temperature SMT processes.
• Designed for harsh environments: −55°C to +105°C operating window and AEC-Q200 qualification support use in temperature-extreme and vibration-prone systems.
• Proven endurance: Rated for 1000 hours at 105°C with defined post-test limits for capacitance, tan δ, and leakage current, providing predictable long-term behavior.
• Compact, automated assembly ready: Radial-can SMD form factor and carrier-tape compatibility enable automated placement in high-volume production.
• Clear electrical characterization: Published leakage current and tan δ limits and low-frequency/high-frequency ripple current figures allow straightforward component selection for power designs.
• Regulatory compliance: RoHS conformity for environmentally regulated products and markets.
