UPW2C470MHD

The UPW2C470MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial‑lead can designed for power applications. It provides 47 µF capacitance at a 160 V rating with low impedance characteristics targeted for switching power supplies and demanding electronic power circuits.

Key value comes from its compact φ12.5 × 25 mm can, AEC‑Q200 rating, and extended endurance — rated for 7,000 hours at 105°C — making it suitable for long‑life, high‑temperature environments.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a rated voltage of 160 V and tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Reliability & Endurance — Endurance specified at 7,000 hours at 105°C under rated bias and ripple conditions, supporting sustained operation in elevated temperature environments.
• Low Loss / Stability — Dissipation factor (tan δ) of 0.15 measured at 20°C, 120 Hz, providing predictable loss characteristics for power filtering and decoupling.
• High Ripple Handling — Rated ripple currents of 220 mA at 120 Hz and 352 mA at 10 kHz enable effective smoothing in both low‑ and high‑frequency power domains.
• Compact Radial Package — φ12.5 × 25 mm can with 5.0 mm lead spacing (±0.5 mm) and radial lead mounting simplifies board placement in space‑constrained power assemblies.
• Leakage Characteristic — Specified leakage current of 400.8 µA for predictable standby and bias behavior.
• Automotive‑grade Qualification — AEC‑Q200 rating indicates suitability for automotive electronics design flows and qualification processes.
• RoHS‑aware Configuration — Part code and series configuration correspond to Pb‑free leadwire and Pb‑free PET sleeve options for the 12.5 mm diameter package.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output decoupling where low impedance and reliable high‑temperature endurance are required.
• Automotive Power Electronics — Energy storage and ripple suppression in automotive control modules and power converters, supported by AEC‑Q200 qualification.
• DC–DC Converters — Input/output filtering for converters operating with elevated DC bus voltages up to 160 V and demanding ripple currents.
• Industrial Power Systems — Local decoupling and energy buffering in compact power assemblies exposed to extended high‑temperature duty cycles.

Unique Advantages

• High‑Voltage Capability: 160 V rated voltage enables use in higher DC bus and intermediate‑bus circuits without upsizing the capacitor footprint.
• Extended High‑Temperature Life: 7,000 hours at 105°C provides predictable service life for designs exposed to elevated ambient or internal temperatures.
• Measured Ripple Performance: Specified ripple currents at both 120 Hz (220 mA) and 10 kHz (352 mA) give designers clear, frequency‑dependent thermal margins.
• Compact, Serviceable Form Factor: φ12.5 × 25 mm radial can with 5.0 mm lead spacing fits tight board layouts while remaining easy to mount and replace.
• Automotive‑ready Qualification: AEC‑Q200 rating aligns the part with automotive component qualification practices for system‑level development.
• Pb‑free Leadwire and Sleeve Configuration: Series configuration for the 12.5 mm diameter package indicates Pb‑free leadwire and PET sleeve for compliance‑aware assemblies.
