The UCD1H4R7MCL1GS is a chip-type, surface-mount aluminum electrolytic capacitor designed for low-impedance applications. It provides 4.7 µF capacitance at a 50 V rating in a compact φ4 × 5.8 mm chip package suited for automated assembly and high-density PCBs.

Targeted for automotive electronics and other environments requiring AEC‑Q200 qualification, this part combines temperature tolerance, controlled loss (tan δ), and defined ripple-current capability to support reliable power decoupling and filtering in constrained spaces.

Key Features

• Capacitance & Voltage — 4.7 µF nominal capacitance with a rated voltage of 50 V and tolerance of −20% to +20% (±20%).
• Low Impedance & Loss — Low-impedance chip construction with specified impedance of 2.7 Ω and tangent of loss angle (tan δ) of 0.10 measured at 20°C, 120 Hz, supporting stable performance in AC and ripple environments.
• Ripple Current Ratings — Defined ripple-current capability of 30 mA at 120 Hz (low frequency) and 60 mA at 10 kHz (high frequency), enabling reliable handling of AC ripple on power rails.
• Leakage & Polarization — Polarized aluminum electrolytic design with leakage current specified at 3 µA (measured after 2 minutes at rated voltage, 20°C), supporting predictable quiescent behavior.
• Temperature & Endurance — Operating range −55°C to +105°C with endurance specified as 2000 hours at 105°C, delivering sustained performance under elevated-temperature stress.
• Automotive Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant, aligning with automotive-grade reliability and environmental requirements.
• Compact SMD Package & Assembly — Chip-type radial can SMD (φ4 × 5.8 mm) with surface-mount land size 4.3 × 4.3 mm and embossed carrier taping for automatic placement on production lines.

Typical Applications

• Automotive control modules — AEC‑Q200 qualification, 50 V rating and −55°C to +105°C temperature tolerance make this capacitor suitable for power decoupling and smoothing in engine control and body control units.
• Infotainment and gateway systems — Low impedance and defined ripple-current capability help stabilize supply rails in infotainment power supplies and communication gateways.
• Sensor and interface electronics — Compact SMD footprint and low leakage support space-constrained sensor front-ends and interface modules requiring stable capacitance over temperature.
• On-board DC–DC converter output filtering — 50 V rating, low tan δ and ripple-current specifications make the part suitable for filtering and decoupling at converter outputs in automotive electronics.

Unique Advantages

• Automotive-grade qualification: AEC‑Q200 status provides explicit qualification for automotive electronic designs where component-level robustness is required.
• Compact, assembly-ready form: φ4 × 5.8 mm chip package with embossed carrier taping supports high-density PCB placement and automated pick-and-place workflows.
• Performance-backed specifications: Low impedance (2.7 Ω), tan δ = 0.10, and measured ripple-current values give engineers verifiable metrics for power-rail stability and thermal stress planning.
• High-temperature endurance: Rated for 2000 hours at 105°C, providing predictable long-term behavior in elevated-temperature environments.
• Low leakage: Specified leakage current of 3 µA at 20°C supports designs requiring minimal quiescent current and stable bias conditions.
• Regulatory compliance: RoHS compliance ensures adherence to common environmental directives for commercial and automotive production.
