UBY1V272MHL

The UBY1V272MHL is a high-reliability miniature aluminum electrolytic capacitor in Nichicon’s UBY series. It is a radial lead, polarized capacitor rated at 35 V with 2700 µF nominal capacitance and ±20% tolerance.

Designed for high-temperature and high-ripple applications, this part targets demanding automotive and industrial control circuits where elevated operating temperature, high ripple current capability and long endurance are required.

Key Features

• Capacitance and Voltage: 2700 µF (2.7 mF) nominal capacitance with a rated voltage of 35 V and capacitance tolerance of −20% to +20%.
• High ripple current capability: Rated low-frequency ripple current 2.3925 A at 120 Hz and high-frequency ripple current 3.19 A at 100 kHz, enabling effective smoothing in power-rich environments.
• Low equivalent series resistance (ESR): ESR specified at 25 mΩ measured at 20°C / 100 kHz for reduced power loss and improved thermal performance.
• High-temperature endurance: Operates from −40°C to +135°C with an endurance rating of 3000 hours at elevated temperature (applicable to 25–50 V range including this 35 V part).
• Loss characteristics: Tangent of loss angle (tan δ) 0.14 at 20°C, 120 Hz for the 35 V rating (note: for capacitances >1000 µF, tan δ increases per datasheet guidance).
• Mechanical and packaging: Radial lead (can) package, size φ12.5 × 35.5 mm, lead spacing 5.0 mm (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Automotive-grade reliability and compliance: AEC-Q200 qualified and RoHS compliant, qualifying the part for automotive control applications per the product data.
• Leakage current: Specified leakage current 2835 µA (measured condition per product data).

Typical Applications

• Automotive control modules: Power smoothing and energy buffering in control units; suited for modules such as electric power steering and direct injection engine drive as noted for the UBY series.
• Power supply filtering: Bulk and decoupling capacitor for DC–DC converters and regulator output stages where high ripple current handling and low ESR improve stability and thermal performance.
• High-temperature electronics: Use in assemblies that require operation up to +135°C and extended endurance under DC bias plus rated ripple current.

Unique Advantages

• High ripple current capacity: Supports substantial AC current on top of DC bias (3.19 A at 100 kHz), reducing voltage ripple in demanding power circuits.
• Low ESR for efficient operation: 25 mΩ ESR at 100 kHz minimizes I²R losses and heat generation under load.
• Extended high-temperature life: 3000-hour endurance at elevated temperature provides predictable lifetime behavior for high-temperature deployments.
• Automotive-grade qualification: AEC-Q200 qualification and RoHS compliance support use in automotive electronics and regulated applications.
• Compact radial can package: φ12.5 × 35.5 mm size with 5.0 mm lead spacing offers a compact solution for through-hole PCB designs requiring robust capacitance.
