UCW1E470MCL1GS

The UCW1E470MCL1GS is a Nichicon UCW series chip‑type aluminum electrolytic capacitor designed for surface‑mount applications. It delivers 47 µF at 25 V in a compact radial can SMD package sized 7 × 6.3 mm and is intended for demanding environments where temperature stability and long life are required.

Engineered for automotive and other harsh environments, the part is AEC‑Q200 qualified, RoHS compliant, and specified for a -25 °C to +105 °C operating range with a rated load life of 7000 hours at +105 °C. It is also compatible with automated assembly processes using carrier tape.

Key Features

• Electrical Performance — 47 µF nominal capacitance at 25 V with ±20% tolerance and a low impedance characteristic (1.1 Ω) for effective decoupling and filtering.
• Thermal & Life — Rated for continuous operation from -25 °C to +105 °C and specified for 7000 hours of load life at +105 °C, supporting long‑term stability in high‑temperature applications.
• Reliability & Qualification — AEC‑Q200 qualified and RoHS compliant, providing traceable qualification for vehicle electronics and other regulated applications.
• Package & Mounting — Chip‑type radial can SMD (L: 7 × D: 6.3 mm) compatible with carrier‑tape automated placement; recommended PCB land size 6.6 × 6.6 mm.
• Leakage & Loss Characteristics — Datasheet specifies leakage current limits and tan δ parameters for reliable performance following standard test conditions.
• Ripple Capability — Specified ripple current values of 70 mA at 120 Hz and 140 mA at 10 kHz to support AC ripple handling in power circuits.

Typical Applications

• Automotive electronics — Suited for power supply decoupling and filtering in control modules and electronic subsystems that require long life at elevated temperatures.
• Power management — Use in DC‑DC converter outputs and local energy storage where low impedance and reliable ripple handling are needed.
• Embedded control units — Stable capacitance and AEC‑Q200 qualification make it appropriate for electronic control units and similar embedded systems operating up to +105 °C.

Unique Advantages

• Long high‑temperature life: 7000 hours at +105 °C provides extended service life for designs exposed to sustained elevated temperatures.
• AEC‑Q200 qualified: Formal qualification supports use in automotive and other regulated environments requiring component-level reliability evidence.
• Compact SMD package: 7 × 6.3 mm chip‑type can reduces board space while remaining compatible with carrier‑tape automated assembly.
• Low impedance across temperature: Specified low impedance up to +105 °C helps maintain filtering and decoupling effectiveness under thermal stress.
• Measurable ripple handling: Published ripple current ratings at 120 Hz and 10 kHz allow designers to size capacitors against known AC stress conditions.
• RoHS compliant: Meets environmental directive requirements for restricted substances.
