UBY1E202MHL

The UBY1E202MHL is a high-reliability, radial-lead aluminum electrolytic capacitor from Nichicon’s UBY series. It delivers 2000 µF capacitance at a 25 V rating in a compact φ12.5 × 20 mm can and is designed for demanding high-temperature and high-ripple applications.

Engineered for control and power electronics, this capacitor offers high ripple-current capability, low ESR, wide operating temperature range (−40 °C to 135 °C) and an endurance rating of 3000 hours at elevated temperature—making it suitable for robust electronic modules in harsh environments.

Key Features

• Capacitance & Voltage — 2000 µF nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20% for predictable energy storage.
• Low Impedance / Low ESR — ESR of 42 mΩ measured at 20 °C, 100 kHz, supporting efficient power delivery and reduced dissipation.
• High Ripple Current — Low-frequency ripple current of 1.014 A (120 Hz) and high-frequency ripple current of 1.69 A (100 kHz) for effective smoothing under dynamic loads.
• High-Temperature Endurance — Rated for operation from −40 °C to 135 °C with an endurance of 3000 hours at 135 °C under DC bias plus rated ripple current.
• Dielectric Loss (tan δ) — tan δ of 0.16 measured at 20 °C, 120 Hz (accounting for the 2000 µF capacitance), providing a defined dissipation characteristic.
• Leakage Current — Specified leakage current of 1500 µA, supporting predictable standby and bias behavior after voltage application.
• Form Factor & Mounting — Radial lead can with φ12.5 × 20 mm body size, 5.0 mm lead spacing (±0.5 mm), suitable for through-hole assembly. Available in Bulk (no terminal forming) and Bag packing.
• Quality & Compliance — AEC-Q200 listed and RoHS compliant; offered as part of Nichicon’s UBY high-temperature, low-impedance series.

Typical Applications

• Automotive control modules — Power rail smoothing and energy buffering in electronic control units where high ripple current and elevated temperature endurance are required.
• Electric power steering — Filtering and decoupling on motor drive and assist control boards, leveraging the capacitor’s high ripple capability and high-temperature rating.
• Direct-injection engine drive electronics — Bulk decoupling and transient energy supply in fuel-injection control systems operating in harsh thermal environments.
• Power electronics and DC–DC converters — Output filtering and input decoupling where low ESR and defined ripple-handling improve overall converter stability.

Unique Advantages

• High ripple handling: Rated ripple currents (1.014 A at 120 Hz, 1.69 A at 100 kHz) enable reliable filtering under dynamic loads, reducing stress on downstream components.
• Low ESR for efficiency: 42 mΩ ESR at 100 kHz minimizes losses and heat generation, improving power conversion efficiency and thermal performance.
• Designed for high-temperature operation: −40 °C to 135 °C range with 3000-hour endurance at 135 °C supports long-term operation in elevated-temperature environments.
• Automotive-grade qualification: AEC-Q200 listing provides a recognized reliability baseline for designs targeting automotive electronics.
• Compact radial package: φ12.5 × 20 mm can and 5.0 mm lead spacing offer a space-efficient through-hole solution for power modules and controllers.
• Manufacturing readiness: Available in Bulk and Bag packing and listed as mass production, facilitating volume procurement and assembly.
