UBY1E912MHL

The UBY1E912MHL is a high-reliability radial-lead aluminum electrolytic capacitor from Nichicon's UBY series. It delivers 9.1 mF (9100 µF) at 25 V in a compact φ16 × 40 mm can, optimized for demanding temperature and ripple environments.

Designed for automotive and high-temperature control electronics, this part combines high capacitance, substantial ripple-current capability and low ESR to support power smoothing, energy buffering and harsh-environment duty cycles.

Key Features

• Capacitance & Voltage — 9.1 mF (9100 μF) nominal capacitance at a rated voltage of 25 V with ±20% tolerance.
• High Ripple Current — Low-frequency ripple current 3.341 A (120 Hz) and high-frequency ripple current 3.93 A (100 kHz) to handle heavy AC components on DC rails.
• Low ESR — Equivalent series resistance of 19 mΩ measured at 20°C / 100 kHz, reducing loss and self-heating under ripple load.
• Thermal & Endurance Performance — Operating temperature range −40°C to 135°C and endurance rated to 3000 hours at elevated temperature (125°C/135°C conditions specified for the UBY series).
• Electrical Leakage & Dissipation — Specified leakage current 6825 µA and loss tangent (tan δ) 0.3 measured at 20°C, 120 Hz for this part.
• Mechanical & Packaging — Radial leaded package, lead spacing 7.5 mm (±0.5 mm), case size φ16 × 40 mm, available in bulk (no terminal forming) or bag packing.
• Qualification — AEC‑Q200 listed in the product specifications for applications requiring recognized reliability standards.

Typical Applications

• Automotive control systems — Suited for control modules such as electric power steering and direct injection engine drive, where high capacitance and ripple handling at elevated temperature are required.
• Power electronics supply smoothing — Bulk energy storage and smoothing on DC rails subject to high ripple currents and thermal stress.
• Harsh-environment controllers — Electronics that operate across −40°C to 135°C and demand long endurance under continuous bias and ripple loading.

Unique Advantages

• High energy density in a compact can — 9.1 mF in a φ16 × 40 mm package provides substantial bulk capacitance where board space is limited.
• Ripple-capable design — Rated ripple currents (3.341 A at 120 Hz; 3.93 A at 100 kHz) enable reliable operation in converters and motor-control supplies.
• Low electrical losses — 19 mΩ ESR at 100 kHz minimizes I²R losses and temperature rise under load.
• High-temperature endurance — Specified for operation to 135°C with endurance ratings up to 3000 hours, supporting long-term stability in hot environments.
• Automotive-grade qualification — AEC‑Q200 inclusion supports designs targeting automotive and similar reliability-focused markets.
• Standard radial-lead form factor — 7.5 mm lead spacing and common can size simplify integration into existing PCB layouts and through-hole assemblies.
