UBY1V272MHL6

The UBY1V272MHL6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UBY series. It is a radial-lead, polarized capacitor specified at 2.7 mF (2700 µF) and 35 V, designed for applications that require high capacitance and elevated temperature capability.

Built for demanding environments, this part delivers high ripple-current handling and low impedance across a wide temperature range (−40 °C to 135 °C), with AEC-Q200 qualification and RoHS compliance for automotive and industrial control electronics.

Key Features

• High capacitance in a compact can — 2700 µF (2.7 mF) in a φ18 × 20L package provides substantial bulk capacitance in a small radial-can footprint.
• Rated voltage — 35 V DC nominal rating for common in-vehicle and industrial power rails.
• High ripple-current capability — Low-frequency ripple current 1.4025 A (120 Hz) and high-frequency ripple current 1.87 A (100 kHz) support demanding smoothing and filtering duties.
• Low impedance / low ESR — ESR = 30 mΩ at 20 °C / 100 kHz for improved high-frequency performance and thermal management.
• Wide operating temperature — Rated for −40 °C to 135 °C, with endurance specified up to 3000 hours at elevated temperatures for reliable long-term operation.
• High reliability & automotive readiness — AEC-Q200 qualified and designed for high-temperature automotive control circuits; the UBY series emphasizes higher capacitance and higher ripple current than comparable series.
• Design and assembly — Radial lead mounting with 7.5 mm lead spacing (±0.5 mm) and bulk/bag packing options for production flexibility.
• Electrical basics — Capacitance tolerance ±20%, tangent of loss angle (tan δ) 0.14 at 20 °C / 120 Hz, and leakage current 2835 µA as specified.

Typical Applications

• Automotive control modules — Suited for in-vehicle control circuits, including electric power steering and direct injection engine drive, where high ripple current and elevated temperature endurance are required.
• Power supply smoothing in harsh environments — Bulk energy storage and smoothing for power rails exposed to high temperature and vibration.
• High-frequency decoupling — Low ESR at 100 kHz supports high-frequency filtering and stability of switching regulators in compact assemblies.

Unique Advantages

• Engineered for high ripple conditions: Specified ripple currents at both low and high frequency (1.4025 A @ 120 Hz; 1.87 A @ 100 kHz) reduce voltage ripple and thermal stress in power circuits.
• High-temperature endurance: Rated to operate from −40 °C to 135 °C with endurance specified up to 3000 hours at elevated temperature for prolonged service life in demanding applications.
• Low ESR for improved efficiency: 30 mΩ ESR at 100 kHz lowers I2R losses and improves regulator performance at switching frequencies.
• AEC-Q200 qualified: Meets automotive component qualification for designers targeting vehicle electronics and other high-reliability systems.
• Compact form factor: φ18 × 20L can delivers high capacitance density for space-constrained designs while maintaining radial-lead simplicity for through-hole mounting.
• RoHS compliant and production-ready: Mass-production status and RoHS compliance simplify sourcing and regulatory compliance.
