UBY2A751MHL

The UBY2A751MHL is a radial-lead aluminum electrolytic capacitor from Nichicon's UBY series, designed for high-temperature, low-impedance applications. It provides 750 µF capacitance at a 100 V rating with polarization and is built for demanding environments with an operating range of –40°C to +135°C.

Targeted at control and power circuits that require high ripple handling and reliable operation at elevated temperatures, this component delivers measurable performance in endurance, ripple current capability, and low ESR while offering AEC-Q200 qualification and RoHS compliance.

Key Features

• Capacitance & tolerance — 750 µF with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated voltage — 100 V DC for higher-voltage rail applications.
• Temperature range & endurance — Specified for –40°C to +135°C; endurance rating of 2000 hours at 135°C for the 63–100 V class.
• Ripple current capability — Low-frequency ripple current of 2.202 A (120 Hz) and high-frequency ripple current of 3.67 A (100 kHz), supporting circuits with significant AC content on DC rails.
• Low ESR — Equivalent series resistance of 25 mΩ at 20°C / 100 kHz for improved filtering and thermal performance.
• Leakage current — Specified leakage current of 2250 µA.
• Mechanical & mounting — Radial can: Ø16 × 40 mm, lead spacing 7.5 mm (±0.5 mm); supplied in bulk (no terminal forming) or bag packing.
• Quality & compliance — AEC-Q200 qualified and RoHS compliant for regulated manufacturing and automotive-oriented design flows.

Typical Applications

• Automotive control circuits — Suited for systems such as electric power steering and direct injection engine drive where elevated temperature endurance and AEC-Q200 qualification are required.
• High-temperature power electronics — Filters and energy-storage stages in electronics exposed to sustained high operating temperatures up to +135°C.
• High-voltage DC rails — Bulk filtering and ripple absorption on higher-voltage rails that require 100 V rating and substantial ripple current handling.

Unique Advantages

• High ripple-current capability: Provides 2.202 A at 120 Hz and 3.67 A at 100 kHz, enabling reliable AC ripple handling in power stages.
• Low high-frequency impedance: 25 mΩ ESR at 100 kHz reduces voltage ripple and improves thermal behavior under AC load.
• High-temperature endurance: Rated for 2000 hours at 135°C (63–100 V class), supporting long-term operation in hot environments.
• Automotive-grade qualification: AEC-Q200 rating supports use in regulated automotive design processes and component selection.
• Compact radial form factor: Ø16 × 40 mm can with 7.5 mm lead spacing offers a standardized radial footprint for through-hole mounting and easy PCB integration.
• Supply and handling options: Available in bulk (no terminal forming) or bag packing to match assembly and inventory workflows.
