UBY1V182MHL

The UBY1V182MHL is a radial-lead aluminum electrolytic capacitor with 1.8 mF capacitance and a 35 V rated voltage, engineered for high-temperature, high-ripple applications. It combines high capacitance density, low ESR, and extended endurance to support power smoothing and decoupling in demanding environments.

Designed for automotive and other harsh-environment power electronics, this AEC-Q200 qualified, RoHS-compliant component provides robust performance across –40°C to 135°C and is optimized for circuits that require sustained ripple current and long-term high-temperature operation.

Key Features

• Capacitance and Tolerance — 1.8 mF (1800 µF) with ±20% tolerance at 120 Hz, 20°C, suitable for bulk energy storage and decoupling.
• Rated Voltage — 35 V DC rating for mid-voltage power rails and DC link applications.
• High Ripple Current — Low-frequency ripple current 1.206 A at 120 Hz and high-frequency ripple current 2.01 A at 100 kHz to support dynamic load conditions.
• Low ESR — Equivalent series resistance of 33 mΩ measured at 20°C/100 kHz, reducing losses and heat generation under AC ripple.
• Extended High‑Temperature Endurance — Rated endurance of 3000 hours at 135°C under DC bias plus rated ripple current, supporting long-term reliability in elevated temperatures.
• Wide Operating Temperature — Specified for –40°C to 135°C operation for use in temperature-challenging environments.
• Package and Mechanical — Radial can package, size φ12.5 × 25 mm (diameter × length) with 5.0 mm lead spacing and lead spacing tolerance ±0.5 mm; available in bulk/bag packing.
• Quality and Compliance — AEC-Q200 qualified and RoHS compliant, meeting automotive-grade qualification and environmental requirements.

Typical Applications

• Automotive control circuits — Smoothing and decoupling in systems such as electric power steering and direct injection engine drive where high ripple handling and high-temperature endurance are required.
• Power supply filtering — Bulk filtering and transient suppression on mid-voltage rails in power modules operating at elevated temperatures.
• High-temperature electronics — Energy storage and decoupling in control modules and power electronics designed for continuous operation up to 135°C.

Unique Advantages

• High ripple capability: Specified low- and high-frequency ripple current ratings enable stable performance under dynamic load conditions, reducing the need for parallel components.
• Low energy losses: 33 mΩ ESR at 100 kHz minimizes dissipation and self-heating, improving system efficiency under AC ripple.
• Long high‑temperature life: 3000 hours endurance at 135°C provides predictable longevity in elevated-temperature applications.
• Automotive-grade qualification: AEC-Q200 rating supports integration into automotive control and other safety-conscious designs.
• Compact radial can: φ12.5 × 25 mm package with 5 mm lead spacing offers a space-efficient option for through-hole assemblies.
• Regulatory compliance: RoHS compliant to meet environmental requirements across supply chains.
