UBY1V472MHL

The UBY1V472MHL is a 4700 µF, 35 V radial-lead aluminum electrolytic capacitor from Nichicon's UBY series, optimized for high-temperature and high-ripple applications. It combines a compact radial-can package (φ16 × 35.5 mm) with engineering-focused electrical characteristics for demanding control circuits.

Designed for rugged environments, this AEC‑Q200 qualified, RoHS-compliant part supports continuous operation from −40°C to 135°C and a rated endurance of 3000 hours at elevated temperatures, delivering stable capacitance and ripple handling where reliability matters.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) rated at 35 V with a tolerance of −20% to +20% for bulk energy storage and decoupling in power rails.
• High ripple-current capability — Low-frequency ripple current 3.086 A at 120 Hz and high-frequency ripple current 3.63 A at 100 kHz to support power conversion and motor-control circuitry.
• Low ESR — Equivalent series resistance of 20 mΩ measured at 20°C / 100 kHz, helping reduce dissipation and improve filtering performance at high frequencies.
• High-temperature endurance — Rated for operation from −40°C to 135°C with an endurance specification of 3000 hours at elevated temperature (applicable to the 25–50 V range), enabling long-term use in heat-stressed designs.
• Leakage and dissipation — Specified leakage current of 4935 µA and tangent of loss angle (tan δ) of 0.18 measured at 20°C, 120 Hz, providing defined electrical behavior for system-level budgeting.
• Package & mounting — Radial lead, can-type package with φ16 mm diameter, 35.5 mm length, and 7.5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for board assembly flexibility.
• Quality & compliance — AEC‑Q200 qualified and RoHS compliant, reflecting suitability for high-reliability applications and regulated environmental requirements.

Typical Applications

• Automotive control systems — Energy storage and ripple suppression in vehicle control modules, benefiting from AEC‑Q200 qualification and extended temperature range.
• Electric power steering — Bulk decoupling and high-ripple handling for power electronics in steering assist modules.
• Direct injection engine drive — Filtering and energy buffering in fuel injection control units where thermal and electrical stress are common.
• Power conversion and motor drives — Upstream and downstream smoothing in inverters and motor controllers that demand high ripple current and low ESR.

Unique Advantages

• High ripple capacity: Rated ripple currents of 3.086 A (120 Hz) and 3.63 A (100 kHz) reduce heating and extend system reliability under dynamic loads.
• Low dissipation losses: 20 mΩ ESR at 100 kHz minimizes I²R losses and improves efficiency in high-frequency power stages.
• Robust thermal capability: −40°C to 135°C operating range and 3000-hour endurance at elevated temperature support long-term operation in hot environments.
• Automotive-grade qualification: AEC‑Q200 status provides traceable quality and suitability for demanding control electronics where component qualification is required.
• Compact radial form factor: φ16 × 35.5 mm can with 7.5 mm lead spacing balances space efficiency with ease of through-hole mounting and replacement.
• Regulatory compliance: RoHS compliance ensures alignment with environmental directives for modern electronics production.
