UBY1K102MHL

The UBY1K102MHL is a radial-lead aluminum electrolytic capacitor from Nichicon’s UBY series, rated at 1000 µF and 80 V. Designed for high-temperature and high-ripple-current environments, it combines a compact can package (φ16 × 35.5 mm) with low impedance characteristics for demanding power applications.

Targeted at control and power electronics—including automotive control circuits—the part delivers a combination of high ripple current capability, low ESR, and extended endurance at elevated temperatures up to 135°C.

Key Features

• Capacitance & Tolerance: 1000 µF with a tolerance of −20% to +20% (120 Hz, 20°C).
• Voltage Rating: 80 V DC rated voltage for higher-voltage power rails.
• High-Temperature Endurance: Rated for operation from −40°C to +135°C with an endurance specification of 2000 hours at 135°C.
• Low Impedance / Low Loss: tan δ = 0.08 (120 Hz, 20°C) and ESR = 27 mΩ at 20°C/100 kHz for reduced heat generation and improved efficiency.
• High Ripple Current Capability: Low-frequency ripple current 2.052 A (120 Hz) and high-frequency ripple current 3.42 A (100 kHz) to support high-dynamic power supply loads.
• Leakage Current: Specified leakage current of 2400 µA.
• Package & Mounting: Radial lead, can package with φ16 × 35.5 mm body and 7.5 mm lead spacing (±0.5 mm).
• Qualification: AEC-Q200 qualified; RoHS compliant.
• Packaging Options: Available in bulk (no terminal forming) and bag packing for flexible assembly logistics.

Typical Applications

• Automotive control circuits: Suited for vehicle electronic control units where high ripple current and elevated operating temperatures are present.
• Electric power steering systems: Provides smoothing and energy buffering for steering control electronics exposed to thermal stress.
• Direct injection engine drive: Supports power-decoupling and transient handling in injection driver circuits operating at high temperature.

Unique Advantages

• Designed for high-temperature operation: Rated to 135°C with a specified endurance of 2000 hours at that temperature, enabling use in thermally stressed assemblies.
• High ripple-current handling: Specified LF and HF ripple currents (2.052 A at 120 Hz, 3.42 A at 100 kHz) reduce the need for parallel capacitors in high-dynamic power circuits.
• Low ESR at high frequency: 27 mΩ at 100 kHz lowers conduction losses and improves converter efficiency.
• AEC-Q200 qualification: Supports designs that require automotive-grade component qualification.
• Compact radial-can footprint: φ16 × 35.5 mm body and standard 7.5 mm lead spacing simplifies layout for through-hole board designs.
