UBY1H182MHL

The UBY1H182MHL is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UBY series designed for high‑temperature, high‑ripple applications. This polarized, high‑reliability component delivers 1800 μF at 50 V in a compact φ16 × 30.5L package with 7.5 mm lead spacing.

Targeted at demanding control and power circuits, the part combines high ripple current capability and low ESR with a wide operating range (−40 °C to 135 °C) and AEC‑Q200 qualification for applications that require extended endurance at elevated temperatures.

Key Features

• Capacitance & Voltage — 1800 μF nominal capacitance at a rated voltage of 50 V with tolerance −20% to +20%.
• Low Impedance / ESR — ESR of 29 mΩ measured at 20 °C and 100 kHz, supporting high‑frequency decoupling and low loss at switching frequencies.
• High Ripple Current — Low‑frequency ripple current 1.776 A (120 Hz) and high‑frequency ripple current 2.96 A (100 kHz), suitable for power supply smoothing under significant AC stress.
• Dissipation Factor — tan δ = 0.1 (measured at 20 °C, 120 Hz), with specified measurement conditions for predictable performance.
• Leakage Current — Specified leakage current of 2700 μA, measured per product criteria.
• High‑Temperature Endurance — Rated for 3000 hours at elevated temperature (specified for 125 °C and 135 °C conditions), allowing use in sustained high‑temperature environments.
• Operating Temperature Range — −40 °C to 135 °C for use across wide thermal environments.
• Mechanical & Mounting — Radial lead, can style package with φ16 × 30.5L dimensions and 7.5 mm lead spacing (±0.5 mm); supplied in Bulk (No Terminal Forming) or Bag packing.
• Standards & Compliance — RoHS compliant and AEC‑Q200 qualified (see product documentation for details).

Typical Applications

• Automotive control circuits — Designed for automobile control circuits such as electric power steering and direct injection engine drive where high ripple current and elevated operating temperature are required.
• Power supply filtering — High ripple current capacity and low ESR make it suitable for smoothing and decoupling in DC‑DC converters and onboard power modules operating at elevated temperatures.
• High‑temperature power electronics — Recommended where sustained operation at up to 135 °C and extended endurance (3000 h) are needed.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 1.776 A (120 Hz) and 2.96 A (100 kHz) reduce heating and extend service life in AC‑stressed power circuits.
• Low ESR at switching frequencies: 29 mΩ ESR at 100 kHz supports efficient filtering for high‑frequency switching regulators.
• Extended high‑temperature endurance: 3000 hours rated endurance at elevated temperature allows reliable use in hot environments and demanding duty cycles.
• Compact radial can package: φ16 × 30.5L dimensions and standard 7.5 mm lead spacing provide a small footprint for space‑constrained board layouts while maintaining performance.
• Qualification and compliance: AEC‑Q200 qualification and RoHS compliance provide traceable quality and environmental conformance for regulated applications.
