UBY1E512MHL

The UBY1E512MHL is an aluminum electrolytic capacitor from Nichicon’s UBY series, offering 5100 µF capacitance at a 25 V rating in a radial‑lead can (φ12.5×40 mm). It is designed for high‑temperature operation and high ripple environments, with a wide operating temperature range of −40 °C to +135 °C and a rated endurance of 3000 hours at elevated temperature.

This part is targeted at automotive and industrial control applications where high capacitance, high ripple capability and robust endurance are required. Key value propositions are its high ripple current handling, low equivalent series resistance, and AEC‑Q200 qualification combined with RoHS compliance.

Key Features

• Capacitance & Voltage: 5100 µF nominal capacitance at a 25 V rated voltage with ±20% tolerance, suitable for bulk energy storage and decoupling in power rails.
• High Temperature Endurance: Specified to operate from −40 °C to +135 °C with a rated life of 3000 hours at the upper temperature limit (25–50 V range), enabling use in high‑thermal environments.
• High Ripple Current Capability: Low‑frequency ripple current 2.9495 A (120 Hz) and high‑frequency ripple current 3.47 A (100 kHz), supporting circuits with substantial AC ripple on DC rails.
• Low ESR: ESR of 24 mΩ measured at 20 °C/100 kHz, minimizing power loss and heating under ripple load.
• Leakage and Loss Characteristics: Leakage current specified at 3825 µA and a tangent of loss angle (tanδ) of 0.22 (measured at 20 °C, 120 Hz) for predictable performance in bias applications.
• Package & Mounting: Radial lead can with φ12.5×40 mm dimensions, 5.0 mm lead spacing (±0.5 mm), supplied in bulk/no terminal forming or bag packing for straightforward through‑hole assembly.
• Qualification & Compliance: AEC‑Q200 qualified and RoHS compliant, aligning with quality and environmental standards for demanding applications.

Typical Applications

• Automotive Control Electronics: Energy buffering and smoothing in electronic power steering, engine control modules and other on‑board control units where high temperature and high ripple are present.
• Power Supply Filtering: Bulk decoupling and ripple attenuation on DC power rails in converters and motor drive systems that require low ESR and sustained ripple handling.
• Industrial Drive Systems: Filtering and energy storage for inverter and drive circuits operating in elevated ambient temperatures.

Unique Advantages

• High Capacitance in a Compact Can: 5100 µF in a φ12.5×40 mm package provides substantial energy storage without a large footprint.
• Designed for Elevated Temperatures: Rated to operate up to +135 °C with a 3000‑hour endurance specification, supporting robust operation in hot environments.
• Measured Low ESR at High Frequency: 24 mΩ at 100 kHz reduces conduction losses and thermal stress under high ripple conditions.
• High Ripple Current Ratings: Specified ripple currents at 120 Hz and 100 kHz support both low‑ and high‑frequency power applications.
• AEC‑Q200 Qualification: Provides traceable quality for applications requiring component qualification for harsh environments.
• Supply Options for Production: Available in bulk or bag packing for flexible procurement and assembly workflows; part is listed as mass production.
