UZR1H4R7MCL1GB

The UZR1H4R7MCL1GB is a surface-mount aluminum electrolytic capacitor in Nichicon’s UZR series. It delivers 4.7 µF capacitance at a 50 V rating in a compact chip-style can (L: 3.9 × D: 5 mm) designed for high-density PCB assemblies.

Engineered for automotive-grade applications, this AEC-Q200 rated, RoHS-compliant component combines low leakage and controlled dissipation factor with packaging optimized for automated assembly.

Key Features

• Electrical Performance — 4.7 µF capacitance with ±20% tolerance and a rated voltage of 50 V; tangent of loss angle (tanδ) specified at 0.14 (20°C, 120 Hz, 50 V).
• Leakage and Ripple Characteristics — Low leakage current specified at 3 µA and ripple current ratings of 20 mA (120 Hz) and 30 mA (10 kHz) for stable operation under AC stress.
• Automotive Qualification — AEC-Q200 rating identified in the product specifications for suitability in automotive electronic applications.
• Temperature and Endurance — Operating temperature range of −40°C to 85°C and endurance rated to 1000 hours at 85°C with defined post-test limits for capacitance, tanδ, and leakage.
• Compact SMD Can Package — Chip-type radial can in an SMD form factor (φ5 × 3.9 mm) with surface-mount land pattern L: 5.3 × W: 5.3 mm, suitable for automated placement from embossed carrier tape.
• Assembly-Friendly Packaging — Supplied in embossed carrier taping to support automatic pick-and-place mounting on high-density PCBs.

Typical Applications

• Automotive Electronics — Designed for use in automotive electronic modules that require AEC-Q200-rated surface-mount electrolytic capacitors.
• Board-Level Power Rails — Compact SMD can for decoupling and local energy storage on tightly packed power distribution networks.
• Industrial Embedded Systems — Suitable where a ruggedized, polarized electrolytic capacitor with defined endurance at elevated temperature is required.

Unique Advantages

• AEC-Q200-rated for automotive use: Explicit AEC-Q200 listing supports selection for automotive environments requiring qualification-level components.
• Small, board-friendly package: φ5 × 3.9 mm chip can and compatible land pattern enable high-density PCB layouts and automated assembly.
• Low leakage: Specified leakage current of 3 µA minimizes standby current impact in sensitive circuits.
• Defined AC performance: Specified tanδ (0.14 at 50 V, 20°C, 120 Hz) and ripple current ratings help predict AC behavior in power applications.
• Temperature and endurance specifications: −40°C to 85°C operating range and 1000 hours endurance at 85°C give clear reliability boundaries for thermal design and lifetime planning.
• RoHS compliant and tape-packaged: Meets RoHS requirements and is supplied in embossed carrier taping for streamlined SMT production.
