UBW1K470MPD

The UBW1K470MPD is a miniature, radial‑lead aluminum electrolytic capacitor designed for high‑temperature, high‑reliability applications. It provides 47 µF capacitance at an 80 V rating in a compact φ10 × 12.5 mm can with 5 mm lead spacing.

With an operating temperature range of −55 °C to +135 °C, AEC‑Q200 qualification, and a rated endurance of 2000 hours at 135 °C, the UBW1K470MPD is targeted at demanding electronics that require durable smoothing, decoupling and energy‑storage components in constrained spaces.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with an 80 V rated voltage and tolerance of −20% to +20% for predictable charge storage.
• High‑Temperature Endurance: Rated for −55 °C to +135 °C and specified life of 2000 hours at 135 °C, supporting sustained operation in elevated ambient conditions.
• Reliability & Qualification: AEC‑Q200 rating and long‑life specification for use in applications requiring component qualification and stability over time.
• Low Loss Characteristics: tanδ (DF) of 0.08 measured at 20 °C, 120 Hz and 80 V, enabling efficient energy transfer with controlled dissipation.
• Ripple & Leakage Performance: Low frequency ripple current 321.6 mA (120 Hz), high frequency ripple current 480 mA (10 kHz), and leakage current of 112.8 µA for reliable filtering under ripple load.
• Compact Radial Lead Package: φ10 × 12.5 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through‑hole assembly and robust mechanical mounting.
• Packaging & Availability: Available in bulk (no terminal forming) or bag packing and currently in mass production.

Typical Applications

• Automotive electronics: Bulk energy storage and power smoothing in automotive systems where AEC‑Q200 qualification and +135 °C endurance are required.
• Power supply filtering: Decoupling and ripple suppression in high‑voltage (>50 V) supply rails up to 80 V, leveraging specified ripple current and low dissipation factor.
• Industrial controls: Compact, reliable capacitance for control electronics exposed to wide temperature swings and long operational lifetimes.

Unique Advantages

• High‑temperature performance: Operation to +135 °C with a 2000‑hour endurance rating provides predictable behavior in thermally challenging environments.
• AEC‑Q200 qualified: Delivers a recognized reliability standard for applications requiring automotive‑grade component screening and characterization.
• Balanced ripple handling: Specified ripple currents at low and high frequencies (321.6 mA @120 Hz, 480 mA @10 kHz) support mixed‑frequency power environments.
• Low dissipation factor: tanδ = 0.08 at 80 V, 120 Hz reduces heat buildup and improves efficiency in AC/ripple conditions.
• Compact radial package: φ10 × 12.5 mm can and 5 mm lead spacing enable space‑constrained PCB layouts while retaining through‑hole robustness.
• Controlled leakage: Specified leakage current of 112.8 µA for predictable standby and bias behavior.
