UCW1H470MNL1GS

The UCW1H470MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon’s UCW series, offering 47 µF capacitance at a 50 V rating in a compact surface-mount radial can package. It combines a low-impedance design with long-life endurance for applications that require stable performance at elevated temperature.

Designed for automated assembly, RoHS compliance and AEC-Q200 qualification make this part suitable for demanding markets where long-term thermal stability, automated placement and industry-grade qualification matter.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 50 V rated voltage and tolerance of ±20% (−20% to +20%).
• Long Life Endurance — Load life of 7000 hours at +105 °C. Endurance criteria from the datasheet specify capacitance change within ±30%, tan δ up to 300% of initial specified value, and leakage current less than or equal to the initial specified value after the life test.
• Low Impedance Performance — Low impedance temperature range up to +105 °C with a specified impedance of 530 mΩ, helping maintain filtering and decoupling effectiveness at elevated temperatures.
• Operating Temperature Range — Rated for −25 °C to +105 °C operation to cover a wide range of thermal conditions.
• Ripple Current Capability — 175 mA at 120 Hz and 350 mA at 10 kHz, supporting AC ripple and switching noise suppression across common power frequencies.
• Surface-Mount Packaging & Assembly — Radial, can-style SMD package with nominal size L: 1.0 cm × D: 0.8 cm and recommended land size 8.3 mm × 8.3 mm; compatible with automatic mounting machines fed with carrier tape.
• Standards & Compliance — RoHS compliant (2011/65/EU, (EU)2015/863) and AEC-Q200 qualified.
• Leakage Current Specification — After 2 minutes at rated voltage and 20 °C, leakage current is not more than 0.01CV or 3 µA, whichever is greater (per datasheet specification).

Typical Applications

• Automotive electronic modules — AEC-Q200 qualification, 7000 h life at +105 °C and wide temperature range make this capacitor suitable for in-vehicle control and power modules requiring long-term thermal stability.
• Power supply decoupling and smoothing — 47 µF capacitance with defined ripple current ratings supports bulk decoupling and smoothing in DC/DC converters and power rails.
• Compact board-level power designs — Small radial can SMD package and tape-feed compatibility simplify automated placement in space-constrained PCBs.

Unique Advantages

• Proven high-temperature endurance — 7000 hours at +105 °C provides designers confidence in long-term performance for elevated-temperature environments.
• Low impedance through the operating range — Specified low impedance (530 mΩ) and low-impedance behavior up to +105 °C help maintain effective filtering under thermal stress.
• Automated assembly ready — Carrier-tape compatible package reduces manual handling and speeds production for high-volume manufacturing.
• Automotive-grade qualification — AEC-Q200 qualification supports use in automotive and similarly demanding applications that require recognized component reliability standards.
• Measurable ripple handling — Clear ripple current ratings at 120 Hz and 10 kHz allow engineers to size capacitors against expected AC stress.
