UWJ1V4R7MCL1GB

The UWJ1V4R7MCL1GB is a polarized aluminum electrolytic surface-mount capacitor from Nichicon’s UWJ series. It provides 4.7 µF capacitance at a 35 V rating in a compact φ4 × 5.4 mm radially cased SMD package targeted at compact, high-density PCB power designs.

Designed for reliable operation across −40 °C to +85 °C, the part delivers controlled loss (tanδ) and low leakage for power smoothing, decoupling and energy-storage roles in constrained board space. It is RoHS compliant and AEC-Q200 rated for use in applications requiring validated component-level automotive performance.

Key Features

• Capacitance & tolerance — 4.7 µF with ±20% tolerance at 120 Hz, 20 °C for predictable decoupling and filtering performance.
• Voltage rating — 35 V rated voltage suitable for a range of mid-voltage power rails.
• Loss and leakage — tanδ 0.12 (measured at 120 Hz, 20 °C) and leakage current specified at 3 µA, supporting stable behavior in DC circuits.
• Ripple handling — Specified low-frequency ripple current 18 mA at 120 Hz and high-frequency ripple current 27 mA at 10 kHz for common power-supply conditions.
• Endurance and temperature range — 2000 hours load life at 85 °C and operating range from −40 °C to +85 °C for consistent performance in elevated-temperature environments.
• Compact SMD can package — Radial can SMD chip type with dimensions L: 5.4 × D: 4 mm and recommended land size 4.3 × 4.3 mm for high-density boards.
• Assembly and packaging — Compatible with automatic mounting (carrier tape) and supplied in embossed carrier taping for SMT production; series supports 260 °C peak reflow conditions per datasheet recommendations.
• Compliance — RoHS compliant and AEC-Q200 rated, aligning with regulated manufacturing and automotive component requirements.

Typical Applications

• Automotive electronics — AEC-Q200 rating and wide operating temperature range make it suitable for control modules and auxiliary power circuits.
• Power supply smoothing — 35 V rating and 4.7 µF capacitance provide effective bulk decoupling and output smoothing on compact DC power rails.
• Embedded and industrial control — Small footprint and tape-and-reel compatible packaging support automated assembly for compact controllers and sensor interface boards.

Unique Advantages

• Compact radial can SMD form factor: Small φ4 × 5.4 mm package and defined land pattern enable high-density PCB layouts without sacrificing capacitance.
• Automated assembly ready: Supplied in embossed carrier taping and suitable for automatic mounting machines to streamline production.
• High-temperature reflow compatibility: Series-level reflow capability up to 260 °C peak facilitates standard SMT assembly flows.
• Automotive-capable qualification: AEC-Q200 rating supports designs that require validated component-level reliability for automotive use.
• Predictable electrical performance: Specified tanδ, low leakage current, and ripple current ratings allow engineers to size and verify power circuits with confidence.
• Durability at elevated temperature: 2000 hours rated life at 85 °C provides a defined endurance metric for long-term thermal reliability planning.
