UBY1E622MHL6

The UBY1E622MHL6 is a radial-leaded aluminum electrolytic capacitor from Nichicon’s UBY series. It delivers 6.2 mF capacitance at a 25 V rating in a compact φ18 × 25 mm can package, designed for high ripple-current and high-temperature applications.

Targeted at demanding control and power applications, this part combines high capacitance, low ESR and extended high-temperature endurance to support robust power-smoothing and decoupling in industrial and automotive electronic systems.

Key Features

• Capacitance & Tolerance — 6200 µF (6.2 mF) with ±20% tolerance, suitable for bulk energy storage and smoothing tasks.
• Rated Voltage — 25 V DC rating for mid-voltage power domains.
• High Ripple Current Performance — Low-frequency ripple current 2.465 A (120 Hz) and high-frequency ripple current 2.9 A (100 kHz) to support heavy AC components on DC rails.
• Low Equivalent Series Resistance (ESR) — 25 mΩ at 20°C / 100 kHz, enabling improved efficiency and reduced heating under ripple load.
• Leakage Current — Specified leakage current 4650 µA.
• High-Temperature Endurance — Rated for operation from −40°C to +135°C with endurance specified to 3000 hours at elevated temperature for 25–50 V parts.
• Package & Mounting — Radial lead (can) package, lead spacing 7.5 mm (±0.5 mm), physical size φ18 × 25 mm for through-hole assemblies.
• Quality & Compliance — AEC‑Q200 qualified and RoHS compliant; available in bulk/bag packing and offered in mass production status.

Typical Applications

• Automotive control circuits — Suited for modules that require high ripple handling and high-temperature endurance such as electric power steering and direct injection engine drive.
• Power supply smoothing — Bulk energy storage and post-regulator smoothing where low ESR and high ripple capacity reduce voltage ripple and thermal stress.
• Motor drive electronics — Decoupling and energy buffering in motor controllers that experience high ripple currents and elevated operating temperatures.

Unique Advantages

• High ripple capability: Specified ripple currents at 120 Hz and 100 kHz (2.465 A / 2.9 A) allow the capacitor to handle significant AC stress in power circuits.
• Low ESR for better thermal performance: 25 mΩ ESR at 100 kHz reduces dissipation and helps maintain performance under continuous ripple load.
• High-temperature endurance: Rated to operate to +135°C with 3000-hour endurance at elevated temperature, supporting long-term reliability in hot environments.
• AEC‑Q200 qualification: Meets automotive-grade test standards, making it suitable for designs that require that level of component qualification.
• Compact through-hole form factor: φ18 × 25 mm radial can offers high capacitance in a space-efficient package for board-level power designs.
• Production-ready supply: Mass production status with bulk/bag packing options supports volume procurement and assembly workflows.
