UBY1E302MHL

The UBY1E302MHL is a high-capacitance aluminum electrolytic capacitor in a radial-lead can, designed for demanding, high-temperature environments. With a 3000 µF capacitance and a 25 V rating, it targets automotive and industrial power applications that require sustained ripple handling and extended endurance at elevated temperatures.

Engineered as part of Nichicon’s UBY series, this component emphasizes low impedance and high ripple current capability while meeting AEC-Q200 qualification and RoHS compliance for reliable use in vehicle control circuits and other harsh environments.

Key Features

• Capacitance & Voltage — 3000 µF nominal capacitance with ±20% tolerance and a 25 V rated voltage suitable for bulk energy storage and smoothing in DC power rails.
• High Temperature Endurance — Rated for operation from –40°C to +135°C with an endurance of 3000 hours at elevated temperature (135°C), supporting long-term operation in hot environments.
• High Ripple Current / Low ESR — Low-frequency ripple current of 1.508 A (120 Hz) and high-frequency ripple current of 2.01 A (100 kHz), together with a 33 mΩ ESR (20°C, 100 kHz) for improved power-conditioning performance.
• Leakage Current — Specified leakage current up to 2250 µA (per standard leakage formula 0.03CV), enabling predictable pre-load behavior after voltage application.
• Radial Lead Package — φ12.5 × 25 mm can with 5.0 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assembly and robust mechanical retention.
• Reliability & Qualification — AEC-Q200 qualified and RoHS compliant; supplied in bulk/bag packing for production deployment.

Typical Applications

• Electric Power Steering (EPS) — Energy buffering and smoothing for EPS control modules where high ripple current and elevated temperature tolerance are required.
• Direct Injection Engine Drive — Bulk decoupling and transient support in engine-drive electronics operating in high-temperature engine compartments.
• Automotive Power Electronics — DC link and intermediate power supply smoothing for in-vehicle control units and power converters that demand low impedance and long endurance.
• Industrial Power Modules — Bulk energy storage and filtering in compact through-hole assemblies exposed to elevated ambient temperatures.

Unique Advantages

• High ripple capability: Combines 1.508 A (120 Hz) and 2.01 A (100 kHz) ripple ratings with low ESR (33 mΩ) to reduce voltage ripple and improve regulator stability.
• Extended high-temperature life: Endurance specified at 3000 hours at 135°C provides measurable lifetime performance for hot-zone applications.
• AEC-Q200 qualification: Supplies a recognized reliability baseline for automotive electronics development and qualification cycles.
• Compact radial can: φ12.5 × 25 mm form factor with 5 mm lead spacing offers a space-efficient through-hole solution for high-capacitance needs.
• Production-ready packaging: Available in bulk/bag packing and listed as mass production, facilitating line deployment and procurement planning.
