UBT1H4R7MPD

The UBT1H4R7MPD is a radial-lead aluminum electrolytic capacitor specified at 4.7 µF and 50 V. It is built for high-temperature operation up to +125°C and designed for applications that require sustained performance under elevated-temperature conditions.

This part is AEC-Q200 qualified and RoHS compliant, making it suitable for demanding automotive electronics and other heavy-duty environments that benefit from long load-life and stable filtering/decoupling performance.

Key Features

• Capacitance & Voltage: 4.7 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for precision decoupling and smoothing at moderate voltage levels.
• High-temperature endurance: Rated for operation from −40°C to +125°C with an endurance specification of 2000 hours at +125°C (φ8, ≤50 V), supporting sustained high-temperature use.
• Loss characteristics: Tangent of loss angle (tanδ) specified at 0.1 (measured at 20°C, 120 Hz), providing a defined dissipation factor for AC/ ripple performance planning.
• Ripple current capability: Low-frequency ripple current 42.5 mA at 120 Hz and high-frequency ripple current 85 mA at 100 kHz, enabling predictable thermal and ripple behavior across frequency ranges.
• Leakage current: Specified leakage current of 7.05 µA (measured after voltage application at 20°C), aiding in quiescent-current budgeting for sensitive circuits.
• Mechanical package: Compact radial can, φ8 × 11.5 mm (L), with 3.5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Qualification & compliance: AEC-Q200 qualified and RoHS compliant, aligned with requirements for automotive-grade component selection.
• Product status: End Of Life. Check current stock and availability with sales before planning production use.

Typical Applications

• Automotive electronics: Power decoupling and local smoothing in automotive control modules, sensors, and sub-systems where +125°C operation and AEC-Q200 qualification are required.
• Power supply filtering: Bulk and ripple filtering in compact radial-lead power supplies and converters operating at moderate voltages up to 50 V and elevated temperatures.
• Industrial control: Decoupling and noise suppression in high-temperature industrial electronics and heavy-duty equipment electronics.

Unique Advantages

• High-temperature capability: Rated to +125°C with defined endurance hours, enabling reliable operation in elevated-temperature environments.
• Automotive-grade qualification: AEC-Q200 qualification supports selection for automotive electronics where qualification is required.
• Predictable AC performance: Specified tanδ and ripple current values at both low and high frequencies help engineers size capacitors for thermal and ripple requirements.
• Compact radial form factor: φ8 × 11.5 mm can and 3.5 mm lead spacing provide a small footprint solution for through-hole designs.
• Regulatory compliance: RoHS compliant, supporting environmental requirements for product designs.

Why Choose UBT1H4R7MPD?
