UBT1K470MPD8

The UBT1K470MPD8 is a Nichicon UBT series aluminum electrolytic capacitor in a radial‑lead can, rated 47 µF at 80 V with ±20% tolerance. It is designed for high‑temperature operation up to +125°C and targeted for demanding power applications including automotive electronics where long endurance and stable filter performance are required.

Compact (φ10 × 12.5 mm) and AEC‑Q200 qualified, this capacitor delivers controlled dissipation (tan δ 0.08 at 20°C/120 Hz), low leakage, and defined ripple current capability for reliable DC‑link and decoupling duties in harsh environments.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance at 80 V rated voltage with ±20% tolerance for predictable energy storage and decoupling behavior.
• High‑temperature endurance: Rated for operation from −40°C to +125°C with a specified load life of 3000 hours at +125°C for this diameter (φ10) and voltage range.
• Electrical performance: Low dissipation factor (tan δ = 0.08 at 20°C, 120 Hz) and impedance specified at 800 mΩ to support stable filtering and low losses.
• Ripple handling: 321.6 mA low‑frequency ripple current (120 Hz) and 480 mA high‑frequency ripple current (100 kHz) for continuous ripple suppression in power circuits.
• Leakage current: Rated leakage current of 112.8 µA for predictable stand‑by behavior and minimized parasitic drain.
• Package & mounting: Radial lead, aluminum can package, compact footprint φ10 × 12.5 mm with 5 mm lead spacing; available in bulk or bag packing (no terminal forming).
• Automotive qualification & compliance: AEC‑Q200 qualified and RoHS compliant, suitable for designs requiring industry qualification for electronic components.

Typical Applications

• Automotive electronics: DC‑link and decoupling in control modules and power electronics where +125°C endurance and AEC‑Q200 qualification are required.
• Power supply filtering: Bulk smoothing and ripple suppression in compact power supplies, leveraging the 47 µF capacitance, specified ripple currents, and low tan δ.
• Embedded power modules: Local energy storage and transient buffering on PCBs with limited board area thanks to the φ10 × 12.5 mm compact can.
• Motor drive and inverter circuitry: Decoupling and ripple management in inverter and motor drive systems that operate at elevated temperatures.

Unique Advantages

• High‑temperature capability: Rated to +125°C with specified endurance (3000 hours at this rating and package), enabling designs that operate in elevated‑temperature environments.
• Automotive‑grade qualification: AEC‑Q200 qualification provides documented suitability for automotive electronic designs and related reliability requirements.
• Compact, serviceable form factor: φ10 × 12.5 mm radial can with 5 mm lead spacing fits tight board layouts while preserving serviceability and easy hand or wave mounting.
• Predictable AC performance: Low tan δ (0.08) and defined impedance (800 mΩ) help maintain stable filter behavior across operating conditions.
• Defined ripple handling: Separate low‑ and high‑frequency ripple current specifications (321.6 mA @120 Hz and 480 mA @100 kHz) allow engineers to size capacitors to real‑world ripple profiles.
• Regulatory compliance: RoHS compliant for use in designs requiring restricted‑substance conformity.
