UWT1H470MCL1GS

The UWT1H470MCL1GS is a chip-type aluminum electrolytic capacitor in Nichicon's UWT series, engineered for surface-mount assembly on high-density PC boards. Its core characteristics—47 µF capacitance, 50 V rated voltage and polarized construction—target power filtering and decoupling in demanding environments.

Designed for automotive applications and AEC-Q200 qualification, this RoHS-compliant capacitor offers a wide operating temperature range (−55 °C to +105 °C) and is compatible with automatic placement via carrier tape, supporting efficient manufacturing and robust field performance.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for bulk decoupling and local energy storage.
• Wide Temperature Range — Rated to operate from −55 °C to +105 °C, enabling use across extreme ambient and under-hood conditions.
• AEC-Q200 Qualified — Series qualification for automotive-grade reliability; appropriate for designs requiring AEC-Q200-rated parts.
• Surface-Mount Chip Can — Radial can SMD package designed for placement on high-density PCBs and compatible with automatic mounting machines fed by carrier tape.
• Endurance — Qualified for 1000 hours at 105 °C under rated voltage, with defined limits for capacitance change, tan δ and leakage current after endurance testing.
• Ripple Current — Specified ripple current performance of 63 mA at 120 Hz and 94.5 mA at 10 kHz for thermal and ripple handling considerations in power circuits.
• Compact Footprint — Small package dimensions (7.7 mm length × 6.3 mm diameter) with recommended land size of 6.6 mm × 6.6 mm to support high-density layouts.
• Environmental Compliance — RoHS compliant (2011/65/EU,(EU)2015/863), aligning with regulated material requirements.

Typical Applications

• Automotive power modules — Bulk decoupling and local energy storage for control units and power distribution modules, benefitting from the wide temperature range and AEC-Q200 qualification.
• ECU and control electronics — Power-supply filtering and smoothing in engine, transmission and body control electronics where durability and temperature tolerance are required.
• Sensors and actuator interfaces — Voltage stabilization and transient absorption for sensor front-ends and actuator drivers in harsh environments.

Unique Advantages

• Automotive-grade reliability: AEC-Q200 qualification and defined 1000-hour endurance at 105 °C support use in automotive electronics and other high-reliability systems.
• Wide operating temperature: −55 °C to +105 °C capability ensures stable performance across extreme thermal conditions encountered in vehicle and industrial environments.
• Manufacturing-ready package: SMD radial can designed for carrier-tape feeding and automatic placement, simplifying assembly on high-density PCBs.
