UBT1H470MPD8

The UBT1H470MPD8 is a radial-lead aluminum electrolytic capacitor rated at 47 µF and 50 V with ±20% tolerance. It is designed for high-temperature service up to +125°C and targets demanding automotive and industrial electronics where extended endurance and stable performance at elevated temperatures are required.

With a specified load life of 2000 hours at 125°C, low leakage current, and defined ripple current ratings at both low and high frequencies, this part provides reliable smoothing and decoupling performance in compact, through-hole applications.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance suitable for a range of power filtering and decoupling roles.
• High-Temperature Endurance — Rated for operation from −40°C to +125°C with a specified lifetime of 2000 hours at 125°C for φ8 case sizes, supporting sustained use in high-temperature environments.
• Ripple Current & Impedance — Low-frequency ripple current of 294.8 mA at 120 Hz and high-frequency ripple current of 440 mA at 100 kHz, combined with a typical impedance of 350 mΩ, for effective smoothing under AC ripple conditions.
• Low Leakage & Loss — Leakage current of 70.5 µA and a tan δ of 0.1 at the rated voltage indicate controlled dielectric losses and minimal bleed current in steady-state operation.
• Package & Mounting — Radial lead, can-style package (φ8 × 11.5 mm length) with 3.5 mm lead spacing for easy through-hole assembly and robust mechanical retention.
• Automotive Qualification — AEC-Q200 rated and designed with automotive electronics in mind, meeting requirements for demanding vehicle environments.

Typical Applications

• Automotive Power Modules — Bulk and local decoupling in vehicle power electronics where 50 V rating and high-temperature endurance support long-term operation.
• Engine Control and Powertrain Electronics — Filtering and ripple suppression in control modules operating at elevated temperatures, leveraging the 2000 h life at 125°C.
• In-Vehicle Electronics and Infotainment — Power supply smoothing for onboard systems that require low leakage and defined ripple performance across frequencies.

Unique Advantages

• High-temperature capability: Rated −40°C to +125°C with 2000 hours life at 125°C (φ8 case), enabling reliable use in harsh thermal environments.
• AEC-Q200 qualified: Explicitly qualified for automotive applications, providing confidence for designers targeting vehicle systems.
• Defined ripple performance: Separate low-frequency (294.8 mA at 120 Hz) and high-frequency (440 mA at 100 kHz) ripple current ratings help match component selection to real-world ripple spectra.
• Compact radial package: φ8 × 11.5 mm can with 3.5 mm lead spacing offers a space-efficient, through-hole solution for retrofits and robust PCB mounting.
• Low leakage and controlled dissipation: 70.5 µA leakage and tan δ of 0.1 provide stable leakage behavior and predictable loss characteristics in circuits.
• Clear specification set: Impedance of 350 mΩ and explicit endurance ratings make performance trade-offs and lifetime planning straightforward.
