UBY1H302MHL

The UBY1H302MHL is a 3000 µF, 50 V aluminum electrolytic capacitor in a radial‑lead can designed for high‑temperature, high‑ripple applications. It combines high capacitance, elevated ripple current capability and AEC‑Q200 qualification for demanding electronics environments.

Typical use cases include automotive control and power electronics where high energy storage, low impedance and extended endurance at elevated temperatures are required.

Key Features

• Capacitance & Tolerance: 3000 µF with ±20% tolerance at 120 Hz, 20°C.
• Voltage Rating: 50 V rated voltage suitable for mid‑voltage DC bus and power‑rail applications.
• High ripple current capability: 2.542 A at 120 Hz (low frequency) and 3.39 A at 100 kHz (high frequency) to support demanding power electronics loads.
• Low ESR: 22 mΩ measured at 20°C / 100 kHz, helping reduce heating and improve filtering performance.
• High temperature endurance: Rated for operation from −40°C to +135°C with an endurance of 3000 hours at elevated temperature.
• Leakage current & polarization: Polarized capacitor with specified leakage current of 4500 µA.
• Package & mounting: Radial lead can, size φ18 × 35.5 mm length, lead spacing 7.5 mm (±0.5 mm), supplied bulk or bag packed.
• Quality & compliance: AEC‑Q200 qualified and RoHS compliant for regulated environments and reliability‑focused designs.

Typical Applications

• Automotive control systems: Energy storage and smoothing for subsystems such as electric power steering and direct injection engine drive where high ripple tolerance and temperature endurance are needed.
• Power electronics filtering: DC link and rail filtering in motor controllers and power converters that require high capacitance and low ESR.
• High‑temperature environments: Circuits exposed to elevated ambient temperatures benefiting from a −40°C to +135°C operating range and 3000‑hour endurance.

Unique Advantages

• High energy density: 3000 µF capacitance provides substantial charge storage for bulk decoupling and smoothing in compact radial can format.
• Handles demanding ripple loads: Combined low‑ and high‑frequency ripple ratings (2.542 A @120 Hz, 3.39 A @100 kHz) reduce stress on upstream components and improve system stability.
• Low heater losses: 22 mΩ ESR at 100 kHz minimizes power dissipation, improving thermal performance under ripple and bias conditions.
• Designed for high temperatures: Specified for −40°C to +135°C operation with a 3000‑hour endurance at elevated temperature, supporting long service life in hot environments.
• Automotive‑grade qualification: AEC‑Q200 rating provides an added level of reliability assurance for vehicle electronics designs.
• Supply flexibility: Available in bulk or bag packing to suit production and prototyping workflows.
