UBW1H470MPD

The UBW1H470MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UBW series, specified at 47 µF and 50 V. Engineered for high-temperature operation and long life, this polarized can-style capacitor is optimized for demanding environments that require stable capacitance and endurance at elevated temperatures.

With an operating temperature range of -55°C to +135°C, an endurance rating of 1000 hours at 135°C, and an AEC-Q200 rating, the UBW1H470MPD serves applications where thermal robustness, reliable ripple handling and compact through-hole mounting are required.

Key Features

• Capacitance & Tolerance: 47 µF nominal capacitance with ±20% tolerance (at 120 Hz, 20°C), providing predictable energy storage for filtering and decoupling functions.
• Rated Voltage: 50 V DC rating suitable for mid-voltage power rails and systems.
• High-Temperature Endurance: Rated for operation from -55°C to +135°C with a specified endurance of 1000 hours at 135°C, supporting long-life use in hot operating environments.
• Ripple Current & Low Impedance: Low-frequency ripple current 294.8 mA at 120 Hz and high-frequency ripple current 440 mA at 10 kHz, with an impedance of 350 mΩ—metrics useful for evaluating performance under AC ripple stress.
• Leakage & Loss Characteristics: Specified leakage current of 70.5 µA and tan δ (loss tangent) of 0.10 at 20°C, 120 Hz, enabling predictable leakage and dissipation behavior.
• Physical & Mounting: Compact radial can: diameter φ8 × length 11.5 mm, lead spacing 3.5 mm and radial lead mounting for through-hole assemblies; available in bulk or bag packing.
• Automotive-Grade Reliability: AEC-Q200 rating, indicating qualification for automotive-related electronic applications that demand controlled quality and reliability.

Typical Applications

• Automotive electronics: Designed for use in automotive systems where elevated operating temperatures and long-term reliability are required.
• High-temperature power modules: Suited to power supply circuits and modules that operate or are stored at temperatures up to +135°C and require stable capacitance over life.
• Through-hole board designs: Compact radial can and 3.5 mm lead spacing make this capacitor useful for space-conscious through-hole assemblies and replacement/repair scenarios.

Unique Advantages

• High-temperature capability: Rated to +135°C with 1000 hours endurance at that temperature, enabling use where other electrolytics may degrade faster.
• AEC-Q200 rated: Provides a documented qualification level for automotive applications, supporting design-in for reliability-focused programs.
• Measurable ripple handling: Specified low- and high-frequency ripple currents and low impedance allow engineers to size the capacitor for both 120 Hz and high-frequency ripple conditions.
• Predictable electrical loss and leakage: Defined tan δ and leakage current values at standard test conditions facilitate thermal and leakage budgeting in designs.
• Compact radial form factor: φ8 × 11.5 mm package with 3.5 mm lead spacing supports dense through-hole layouts and mechanical stability on the PCB.
• Production readiness: Listed as mass production with bulk and bag packing options to support prototyping and volume deployment.
