UBY1K271MHL

The UBY1K271MHL is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UBY series, designed for high-reliability applications. It is a polarized, high-temperature capacitor offering 270 µF capacitance at an 80 V rating with a compact radial can package.

Engineered for demanding environments, this part combines a wide operating temperature range (−40°C to 135°C), AEC-Q200 qualification, and measurable low-impedance characteristics for ripple handling and power conditioning in automotive control circuits.

Key Features

• Capacitance & Voltage: 270 µF rated capacitance at 80 V, suitable for decoupling and bulk energy storage in power circuits.
• High Temperature Operation: Rated for operation from −40°C to 135°C to support high-temperature electronic environments.
• Reliability & Qualification: AEC-Q200 qualified and designed as a high reliability type; endurance specified for 2000 hours at 135°C for 63–100 V ratings.
• Low Impedance / Ripple Performance: ESR of 74 mΩ measured at 100 kHz, with ripple current capabilities of 710 mA at 120 Hz and 1.42 A at 100 kHz.
• Package & Mounting: Radial lead, can-style package with 5 mm lead spacing and compact dimensions (L: 2.0 cm × D: 1.25 cm) for through-hole assemblies.
• Tolerance & Polarization: Capacitance tolerance ±20% (at 120 Hz, 20°C); polarized design for correct polarity installation.
• Environmental Compliance: RoHS-compliant construction.

Typical Applications

• Automobile control circuits: Suited for control module power filtering where stability across temperature and vibration is required.
• Electric power steering systems: Provides bulk energy smoothing and ripple suppression in steering control electronics.
• Direct injection engine drive: Supports high-ripple, high-temperature power conditioning demands in fuel-injection control circuits.

Unique Advantages

• AEC-Q200 Qualified: Explicit qualification for automotive applications provides traceable reliability for vehicle systems.
• Wide Temperature Range: Specified −40°C to 135°C operation supports electronics exposed to elevated ambient temperatures.
• Measured Low ESR and High Ripple Capacity: 74 mΩ ESR at 100 kHz with up to 1.42 A ripple at 100 kHz reduces voltage drop and heat in high-frequency power applications.
• Compact Radial Can Footprint: Small L × D dimensions and 5 mm lead spacing enable dense through-hole layouts while retaining robust package construction.
• Endurance at Elevated Temperature: Rated endurance of 2000 hours at 135°C (63–100 V range) supports long-term performance in hot environments.
• Regulatory Compliance: RoHS compliance simplifies environmental and regulatory acceptance in product designs.
