UBY1V512MHL

The UBY1V512MHL is a radial-lead aluminum electrolytic capacitor specified at 5100 µF and 35 V. It is designed for high-temperature operation with an operating range of −40 °C to 135 °C and is produced in a radial can package with 7.5 mm lead spacing.

Engineered for applications that demand high ripple handling and long endurance under elevated temperatures, this part is AEC-Q200 qualified and RoHS compliant, making it suitable for automotive control circuits and other high-temperature power environments.

Key Features

• Capacitance & Voltage — 5100 µF nominal capacitance at a rated voltage of 35 V, with a tolerance of −20% to +20%.
• High Temperature Endurance — Rated for continuous operation from −40 °C to 135 °C with an endurance of 3000 hours at 135 °C under rated conditions.
• High Ripple Current — Handles low-frequency ripple current of 2.95 A (120 Hz) and high-frequency ripple current of 3.47 A (100 kHz), supporting demanding power-conditioning duties.
• Low ESR — Equivalent series resistance of 22 mΩ measured at 100 kHz reduces heat generation and improves efficiency in high-ripple applications.
• Leakage Current — Specified leakage current of 5355 µA for the part as manufactured.
• Packaging & Mounting — Radial lead mounting in a φ18 × 30.5 mm can with 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Automotive-Grade Qualification — AEC-Q200 qualified, supporting use in automotive control circuitry where qualification is required.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Automotive Control Circuits — Suitable for vehicle systems that require stable capacitance and high ripple handling, including electric power steering and direct injection engine drive as noted for the UBY series.
• High-Temperature Power Conditioning — For power electronics operating in elevated ambient temperatures up to 135 °C where sustained ripple capability and longevity are required.
• On-board Power Modules — Radial can format and compact dimensions (L: 30.5 mm × D: 18 mm) make it appropriate for space-constrained assemblies that still demand high capacitance.

Unique Advantages

• High ripple capability: Rated ripple currents at both low and high frequencies (2.95 A @ 120 Hz, 3.47 A @ 100 kHz) reduce voltage stress on the system and help manage thermal load.
• Low ESR performance: 22 mΩ ESR at 100 kHz minimizes losses and supports efficient energy transfer in switching and power supply applications.
• Designed for elevated temperatures: Endurance of 3000 hours at 135 °C provides predictable life characteristics in hot environments.
• Automotive-grade qualification: AEC-Q200 certification supports use in qualified automotive electronics designs.
• Compact radial can: φ18 × 30.5 mm housing with standard 7.5 mm lead spacing simplifies through-hole placement and assembly in existing radial layouts.
• Production-ready supply: Mass-production status with bulk or bag packing options supports scalable BOM procurement.
