UBY1K112MHL

The UBY1K112MHL is a Nichicon UBY-series aluminum electrolytic capacitor in a radial-lead can, rated 1100 µF at 80 V. It targets high-temperature, high-ripple applications with a wide operating temperature range of –40°C to 135°C and AEC-Q200 qualification for automotive-grade deployments.

Designed for power-dense control electronics, this component delivers high ripple-current capability and low ESR in a compact φ18 × 30.5 mm package with 7.5 mm lead spacing, supporting robust performance where thermal and electrical stress are expected.

Key Features

• Capacitance & Tolerance 1.1 mF (1100 µF) with tolerance ±20% at 120 Hz, 20°C, providing stable bulk energy storage for power-supply smoothing and decoupling.
• Rated Voltage 80 V working voltage suitable for higher-voltage control circuits.
• High-Temperature Operation Rated for operation from –40°C to 135°C, enabling use in thermally demanding environments.
• High Ripple Current Low-frequency ripple current 1.932 A (120 Hz) and high-frequency ripple current 3.22 A (100 kHz) for effective handling of both mains and switching ripple.
• Low ESR ESR of 28 mΩ measured at 20°C / 100 kHz to reduce losses and improve thermal performance in power circuits.
• Endurance 2000 hours rated life at 135°C, providing durability for long-term high-temperature operation.
• Package & Mounting Radial lead, can package (φ18 × 30.5 mm) with 7.5 mm lead spacing; available in bulk or bag packing for flexible assembly workflows.
• Compliance & Status AEC-Q200 qualified and RoHS compliant; part is in mass production.

Typical Applications

• Automotive control circuits — Suited for high-temperature vehicle electronics such as electric power steering and direct injection engine drive, where elevated ambient and ripple stresses occur.
• In-vehicle power supplies — Bulk energy storage and ripple smoothing for DC–DC converters and power rails operating at higher voltages and temperatures.
• Motor drive electronics — Filtering and decoupling in motor controllers that require high ripple-current handling and low ESR.

Unique Advantages

• High ripple-current capability: 3.22 A at 100 kHz and 1.932 A at 120 Hz reduce temperature rise under switching loads and improve system reliability.
• Low ESR for efficient power delivery: 28 mΩ (20°C / 100 kHz) lowers losses and supports stable operation in high-frequency environments.
• Extended high-temperature endurance: 2000 hours at 135°C allows deployment in thermally challenging locations without sacrificing lifespan.
• Automotive-grade qualification: AEC-Q200 rating provides design confidence for automotive and other high-reliability applications.
• Compact radial can format: φ18 × 30.5 mm size with 7.5 mm lead spacing offers a space-efficient solution for through-hole assemblies.
• Manufacturing readiness: RoHS compliant and in mass production for predictable sourcing and supply continuity.
