UWF1E4R7MCL1GB

The UWF1E4R7MCL1GB is a surface‑mount, low‑impedance aluminum electrolytic capacitor from Nichicon’s UWF series. It delivers 4.7 µF capacitance at a 25 V rating in a compact chip‑type SMD can (L: 5.4 × D: 4 mm) designed for high‑density PCB assembly.

Built for applications that require compact power decoupling and filtering with extended temperature capability, this part supports operation from −55 °C to +105 °C and meets RoHS and AEC‑Q200 requirements. Note: this product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Capacitance & Voltage: 4.7 µF nominal capacitance with a rated voltage of 25 V and ±20% tolerance for predictable decoupling and filtering behavior.
• Low Impedance Performance: Low‑impedance chip‑type construction with a specified impedance of 5 Ω and a tangent of loss angle (tan δ) of 0.14 at 120 Hz, 20 °C, for effective AC ripple handling.
• Ripple Current Capability: Rated ripple current of 25 mA at 120 Hz and 50 mA at 10 kHz to support both low‑ and high‑frequency ripple conditions.
• Temperature & Lifetime: Wide operating temperature range of −55 °C to +105 °C and an endurance rating of 1000 hours at 105 °C for demanding thermal environments.
• Leakage & Reliability: Leakage current specified at ≤3 µA after 2 minutes at rated voltage and 20 °C, aiding long‑term stability in powered systems.
• Compact SMD Package: Chip‑type radial can SMD package (L: 5.4 × D: 4 mm) with recommended land size 4.3 × 4.3 mm for automated mounting on high‑density PCBs.
• Standards Compliance: RoHS‑compliant and AEC‑Q200 listed, aligning with industry environmental and reliability expectations.

Typical Applications

• Automotive Electronics: Local decoupling and filtering in automotive control modules where AEC‑Q200 qualification and operation up to +105 °C are required.
• Power Supply Filtering: Bulk and post‑regulator filtering in compact DC‑DC converter outputs and point‑of‑load circuits, leveraging the capacitor’s low impedance and ripple ratings.
• High‑Density PCB Designs: Space‑constrained SMD boards that require a small, can‑style electrolytic for smoothing and energy buffering.

Unique Advantages

• Small footprint with high temperature capability: 5.4 × 4 mm SMD can fits tight layouts while supporting −55 °C to +105 °C operation for robust thermal margins.
• Designed for automated assembly: Embossed carrier taping and chip‑type form factor enable reliable pick‑and‑place mounting on high‑density PCBs.
• Balanced AC performance: Specified low impedance, defined tan δ, and ripple current ratings provide clear electrical parameters for power rail design.
• Proven reliability metrics: Endurance 1000 hours at 105 °C and controlled leakage current support predictable long‑term behavior in deployed systems.
• Standards alignment: RoHS compliance and AEC‑Q200 listing streamline use in regulated and automotive contexts.
