UBY1J751MHL6

The UBY1J751MHL6 is a radial-lead aluminum electrolytic capacitor designed for high-temperature, high-ripple applications. It delivers 750 µF capacitance at a 63 V rating in a compact φ16 × 20 mm can with 7.5 mm lead spacing.

Built with AEC-Q200 qualification and RoHS compliance, this capacitor targets demanding automotive and industrial power circuits that require robust ripple handling, low impedance, and extended endurance at elevated temperatures.

Key Features

• Capacitance & Voltage: 750 µF nominal capacitance with a rated voltage of 63 V and tolerance of −20% to +20%.
• High Temperature Capability: Rated for operation from −40°C to 135°C, suitable for thermally demanding environments.
• High Ripple Current: Low-frequency ripple current of 1.146 A at 120 Hz and high-frequency ripple current of 1.91 A at 100 kHz for improved filtering and smoothing performance.
• Low Impedance / Low ESR: ESR of 53 mΩ measured at 20°C / 100 kHz, helping reduce losses and heating in power rail applications.
• Loss Tangent (tan δ): tanδ of 0.1 measured at 20°C, 120 Hz (63 V rating) for predictable AC behavior.
• Endurance: 2000 hours rated lifetime at 135°C for the 63–100 V class, enabling long-term operation under high temperature and voltage stress.
• Leakage Current: Specified leakage current of 1,417.5 µA.
• Package & Mounting: Radial lead can (φ16 × 20 mm), lead spacing 7.5 mm (±0.5 mm); available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Standards Compliance: AEC‑Q200 qualified and RoHS compliant.

Typical Applications

• Electric Power Steering (EPS) Systems: Provides bulk energy storage and smoothing where high ripple tolerance and elevated operating temperature are required.
• Direct Injection Engine Drive Electronics: Supports transient and ripple suppression in engine-control power supplies exposed to high thermal stress.
• Automotive Power Supply Filtering: Suited for DC‑DC converters and on-board power rails that need low ESR and reliable high-frequency ripple handling.
• Industrial Motor Controls: Used for decoupling and smoothing in motor-drive control boards operating in hot environments.

Unique Advantages

• Proven High-Temperature Endurance: 2000 hours rated life at 135°C (63–100 V class) supports long-term reliability in hot operating conditions.
• High Ripple Capacity: Separate low- and high-frequency ripple ratings (1.146 A at 120 Hz and 1.91 A at 100 kHz) enable designers to handle both mains-frequency and switching-frequency stress.
• Low ESR for Reduced Losses: 53 mΩ ESR at 20°C/100 kHz lowers conduction losses and heat buildup in power stages.
• Automotive-Grade Qualification: AEC‑Q200 rating confirms suitability for automotive electronic modules and control circuits.
• Compact Radial Package: φ16 × 20 mm can with standard 7.5 mm lead spacing offers a space-efficient solution for through-hole assemblies.
• Regulatory Compliance: RoHS compliance supports environmental and regulatory requirements for production.\
