UBY1J751MHL

The UBY1J751MHL is a radial lead aluminum electrolytic capacitor with 750 µF capacitance, rated for 63 V operation. It is designed for high‑temperature use and AEC‑Q200 qualification, providing a combination of high ripple handling and low impedance for demanding electronic control environments.

This cylindrical, radial‑lead can (φ12.5 × 30.5 mm) targets automotive and high‑temperature power electronics applications where wide temperature range (−40 °C to 135 °C), elevated ripple current capability, and long endurance at temperature are required.

Key Features

• Capacitance & Voltage: 750 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 63 V, suitable for bulk energy storage and filtering at this voltage level.
• High‑Temperature Operation: Rated operating temperature range −40 °C to 135 °C with specified endurance of 2000 hours at 135 °C under rated conditions.
• Low Impedance / Low ESR: ESR of 42 mΩ measured at 20 °C and 100 kHz, supporting fast transient response and reduced heat generation in high‑frequency applications.
• High Ripple Current Capability: Low‑frequency ripple current 1.578 A at 120 Hz and high‑frequency ripple current 2.63 A at 100 kHz, enabling reliable operation under continuous ripple stress.
• Loss Angle (tan δ): tan δ = 0.1 specified at 20 °C, 120 Hz and 63 V, indicating controlled dielectric loss for this voltage class.
• Leakage Current: Specified leakage current of 1,417.5 µA, consistent with its capacitance and voltage rating for initial leakage behavior.
• Package & Mounting: Radial lead (can) package with 5.0 mm lead spacing (±0.5 mm). Offered in bulk (no terminal forming) or bag packing.
• RoHS & Qualification: RoHS compliant and AEC‑Q200 qualified, addressing regulatory and reliability requirements for regulated and automotive applications.

Typical Applications

• Automotive control electronics: Suited to vehicle control modules and power electronics where AEC‑Q200 qualification and high‑temperature endurance are required.
• Electric power steering and engine control circuits: Applicable to automotive control circuits that demand high ripple handling and stable capacitance at elevated temperatures.
• High‑temperature power converters: Energy storage and smoothing in DC‑DC converters and power modules operating in high ambient temperatures.

Unique Advantages

• Designed for high ripple environments: Specified LF and HF ripple current ratings reduce heating and extend capacitor life under continuous ripple stress.
• Low ESR for improved efficiency: 42 mΩ ESR at 100 kHz lowers conduction losses and supports tighter voltage regulation in power systems.
• High‑temperature endurance: 2000 hours at 135 °C provides predictable performance in elevated temperature applications, supporting long‑term reliability.
• AEC‑Q200 qualification: Enables use in regulated automotive applications that require component-level qualification for reliability.
• Compact radial can size: φ12.5 × 30.5 mm footprint with 5 mm lead spacing balances capacitance and board space for space‑constrained designs.
• RoHS compliant: Meets environmental directives for lead‑free manufacturing and end‑product compliance.
