UBY1J182MHL

The UBY1J182MHL is a radial-lead, high-reliability aluminum electrolytic capacitor from Nichicon's UBY series, rated at 1800 µF and 63 V. It is designed for demanding environments, offering high ripple current capability, low impedance and extended high-temperature endurance for compact power and control electronics.

Targeted for automotive and other high-reliability applications, this miniature can-style capacitor combines a wide operating temperature range with AEC-Q200 qualification and RoHS compliance to support robust circuit designs where ripple handling and thermal stability matter.

Key Features

• Capacitance & Voltage: 1800 µF capacitance at a 63 V rating with a tolerance of -20% to +20% for bulk energy storage and decoupling.
• High Temperature Operation: Rated for operation from -40 °C to 135 °C, with an endurance specification of 2000 hours at 135 °C for the 63 V class.
• High Ripple Current Capability: Low-frequency ripple current of 1.932 A (120 Hz) and high-frequency ripple current of 3.22 A (100 kHz) to support power supply smoothing under real-world ripple loads.
• Low Impedance / Low ESR: ESR specified at 28 mΩ (measured at 20 °C, 100 kHz) to reduce voltage drop and heating in high-current circuits.
• Loss Tangent (tan δ): tan δ of 0.10 at 63 V (measured at 20 °C, 120 Hz), indicating stable dielectric losses for the rated voltage.
• Package & Mounting: Radial lead, can-style package with dimensions φ18 × 30.5 mm and 7.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole assembly.
• Reliability & Compliance: AEC-Q200 qualified and RoHS compliant, suitable for designs requiring industry-recognized reliability and environmental compliance.

Typical Applications

• Automotive Control Electronics: Energy smoothing and decoupling in control modules such as power steering or engine control circuits that demand high ripple tolerance and elevated temperature endurance.
• Power Supply Filtering: Bulk filtering and ripple suppression in DC/DC converters and intermediate rails where low ESR and high ripple current reduce thermal stress.
• Motor Drive and Actuator Systems: Local energy storage and transient handling in motor control and actuator driver circuits that experience high current pulses.

Unique Advantages

• High ripple handling: Specified ripple currents at both 120 Hz and 100 kHz enable reliable operation in both low-frequency power supplies and high-frequency switching environments.
• Thermal robustness: Wide operating range to -40 °C and up to 135 °C plus a defined 2000-hour endurance at 135 °C for the 63 V rating supports long-term operation in hot environments.
• Low ESR performance: 28 mΩ ESR at 100 kHz minimizes I²R losses and heating, improving efficiency and thermal margin on populated boards.
• Compact radial form factor: φ18 × 30.5 mm can with 7.5 mm lead spacing provides a balance of capacitance and board-level density for through-hole assemblies.
• Industry qualification and compliance: AEC-Q200 qualification and RoHS compliance provide traceable suitability for high-reliability and regulated designs.
