UBY1K162MHL

The UBY1K162MHL is a radial-lead aluminum electrolytic capacitor from Nichicon’s UBY series, offering 1600 µF nominal capacitance at an 80 V rating. It is designed for demanding power applications that require high ripple handling, low impedance and extended temperature operation.

Key use cases include automotive and industrial power-control circuits where wide operating temperature range and endurance are required. The part combines high capacitance and high ripple current capability in a compact radial can (φ18 × 40 mm) with 7.5 mm lead spacing.

Key Features

• Capacitance & Voltage: 1600 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance, suitable for energy storage and smoothing in higher-voltage systems.
• High Ripple Current / Low Impedance: Low-frequency ripple current 2.292 A (120 Hz) and high-frequency ripple current 3.82 A (100 kHz), paired with an ESR of 21 mΩ at 100 kHz to minimize heating under AC stress.
• Thermal Endurance: Rated for operation from –40 °C to +135 °C with an endurance rating of 2000 hours at 135 °C, supporting sustained high-temperature operation.
• Loss Factor (tan δ): tan δ = 0.08 measured at 20 °C, 120 Hz, supporting predictable dissipation characteristics.
• Leakage Current: Specified leakage current of 3840 µA for reliable bias behavior after voltage application.
• Package & Mounting: Radial lead, aluminum can package (φ18 × 40 mm) with 7.5 mm lead spacing and bulk or bag packing options for flexible assembly handling.
• Qualification & Compliance: AEC-Q200 qualified and RoHS compliant, aligning with automotive-grade design requirements and environmental directives.

Typical Applications

• Automotive power control units: Energy storage and smoothing in vehicle power electronics where 80 V rating and high ripple capability are required.
• Electric power steering systems: Bulk decoupling and transient suppression in steering control modules that operate across wide temperature ranges.
• Direct injection engine drive modules: High-capacitance filtering for injector drivers and related automotive control circuits.

Unique Advantages

• High ripple handling: Defined low- and high-frequency ripple current ratings (2.292 A at 120 Hz, 3.82 A at 100 kHz) reduce stress on the capacitor under demanding AC conditions.
• Low ESR for efficiency: 21 mΩ ESR at 100 kHz lowers power loss and thermal rise in high-frequency applications.
• Wide temperature capability: –40 °C to +135 °C operating range and 2000-hour endurance at 135 °C support reliable operation in elevated-temperature environments.
• AEC-Q200 qualification: Provides documented suitability for automotive electronic designs that require industry-recognized component qualification.
• Compact radial can: φ18 × 40 mm size with 7.5 mm lead spacing offers a space-efficient footprint for through-hole assemblies.
• RoHS compliant: Meets environmental restrictions for hazardous substances.
