UBY1H162MHL

The UBY1H162MHL is a radial-lead aluminum electrolytic capacitor from Nichicon’s UBY series, rated at 1600 µF and 50 V. It combines high capacitance and elevated ripple-current capability in a compact can-style package suited for demanding control electronics.

Designed for automotive control circuits and other high-temperature applications, this polarized capacitor delivers low impedance, specified high-frequency performance, and extended endurance up to 135 °C.

Key Features

• Capacitance & Rated Voltage — 1600 µF nominal capacitance at 50 V with tolerance −20% to +20%.
• High ripple-current capability — Low-frequency ripple current 1.812 A (120 Hz) and high-frequency ripple current 3.02 A (100 kHz) to support power smoothing and decoupling under heavy load.
• Low ESR — Equivalent series resistance of 32 mΩ measured at 20 °C / 100 kHz for improved efficiency and reduced heating.
• High-temperature endurance — Rated operating temperature −40 °C to 135 °C with endurance of 3000 hours at 135 °C under rated conditions.
• Dielectric loss (tan δ) — tan δ = 0.10 at 20 °C, 120 Hz (50 V rating), ensuring predictable AC performance.
• Polarized radial package — φ12.5 × 40 mm can with 5.0 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Automotive-grade qualification — AEC-Q200 qualified and explicitly specified for automotive applications.
• Environmental compliance — RoHS compliant.

Typical Applications

• Electric power steering (EPS) — Energy smoothing and decoupling in steering control modules, leveraging the capacitor’s high ripple handling and high-temperature endurance.
• Direct injection engine drive — Power filtering and transient suppression in fuel-injection control circuits that demand reliable operation at elevated temperatures.
• Automotive control modules — Bulk energy storage and smoothing for ECUs and motor controllers operating in harsh thermal environments.

Unique Advantages

• Handles heavy ripple loads: Specified ripple currents at 120 Hz and 100 kHz enable reliable filtering under dynamic power conditions.
• Lower thermal loss: 32 mΩ ESR at 100 kHz reduces heat generation in high-frequency environments.
• High-temperature reliability: 3000-hour endurance at 135 °C supports long-term performance in elevated-temperature applications.
• Automotive qualification: AEC-Q200 status and explicit automotive application references make it suitable for vehicle control systems.
• Compact radial form factor: φ12.5 × 40 mm can and 5 mm lead spacing provide a small footprint for through-hole assemblies.
• Regulatory compliance: RoHS conformity for environmental requirements.
