UBY1J252MHL

The UBY1J252MHL is a radial-lead aluminum electrolytic capacitor from Nichicon's UBY series, rated at 2500 µF and 63 V. Engineered for high ripple-current handling and extended high-temperature operation, it targets demanding electronic power and control circuits.

Its combination of high capacitance, low ESR and AEC-Q200 qualification makes it suitable for automotive and other high-reliability applications that require sustained performance at elevated temperatures.

Key Features

• Capacitance & Voltage — 2500 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 63 V DC.
• High Ripple Current — Low-frequency ripple current 2.865 A (120 Hz) and high-frequency ripple current 3.82 A (100 kHz) to support power filtering and decoupling under heavy load.
• Low ESR — Equivalent series resistance of 21 mΩ measured at 20°C and 100 kHz for improved power dissipation and thermal performance.
• High-Temperature Endurance — Operating range −40°C to +135°C with rated endurance of 2000 hours at 135°C (for 63 V parts), supporting elevated-temperature duty cycles.
• Loss Angle (tan δ) — tanδ of 0.12 at 20°C, 120 Hz, with allowance for higher capacitances per datasheet guidance.
• Leakage Current — Specified leakage current of 4,725 µA after rated voltage applied (per part data).
• Mechanical & Mounting — Radial lead (through-hole) can package, body size φ18 × 40L with 7.5 mm lead spacing (±0.5 mm) for straightforward PCB insertion and soldering.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant, aligning with automotive-grade reliability and environmental requirements.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Electric Power Steering — Provides high-capacitance bulk energy and filtering to support power electronics in steering control modules.
• Direct Injection Engine Drive — Supports voltage smoothing and ripple suppression in fuel-injection drive circuits that operate at elevated temperatures.
• Automotive Control Modules — Suited for ECUs and power-control units requiring AEC-Q200-qualified capacitors with high ripple capability and broad temperature range.

Unique Advantages

• High ripple-current capability: Rated ripple currents (120 Hz and 100 kHz) reduce voltage ripple and thermal stress in power conversion and filtering stages.
• Low ESR at high frequency: 21 mΩ at 100 kHz minimizes losses and heat generation in high-speed switching applications.
• High-temperature endurance: Rated for operation to +135°C with specified endurance (2000 hours at 135°C for 63 V), enabling reliable performance in hot operating environments.
• AEC-Q200 qualification: Meeting automotive-grade qualification criteria supports use in vehicle electronics and other high-reliability systems.
• Large capacitance in compact can: 2500 µF in a φ18 can provides substantial bulk energy storage for decoupling and smoothing without excessive board real estate.
• RoHS compliant & production-ready: Environmentally compliant materials and mass-production status simplify integration into commercial production builds.
