UBY1H272MHL

The UBY1H272MHL is a Nichicon UBY-series aluminum electrolytic capacitor in a radial-lead can, rated 2.7 mF (2700 µF) at 50 V. It is designed for high-temperature use with an operating range from −40°C to 135°C and is available in a compact φ16 × 40 mm can with 7.5 mm lead spacing.

This part targets applications that require high capacitance, high ripple-current capability and low equivalent series resistance (ESR). Key value propositions include high ripple handling (both low- and high-frequency), low ESR (22 mΩ @ 100 kHz), and AEC-Q200 qualification for automotive use.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C; rated for 50 V DC.
• High Temperature Operation — Specified operating temperature range of −40°C to 135°C and endurance rated 3000 hours at 135°C (for 25–50 V ratings), supporting sustained high-temperature environments.
• High Ripple Current — Low-frequency ripple current 2.565 A (120 Hz) and high-frequency ripple current 3.42 A (100 kHz), enabling effective smoothing and decoupling under AC ripple stress.
• Low ESR — ESR of 22 mΩ measured at 20°C / 100 kHz, reducing losses and heat generation in high-current circuits.
• Leakage and Dissipation — Specified leakage current 4050 µA and tan δ (DF) of 0.12 at 20°C, 120 Hz for 50 V rating, with DF guidance across the series.
• Package & Mounting — Radial lead can (φ16 × 40 mm) with 7.5 mm lead spacing, available in bulk (no terminal forming) or bag packing for production handling.
• Automotive-Grade Qualification — AEC-Q200 qualified and explicitly referenced for automobile control circuits in the UBY series documentation.
• RoHS Compliant — Conforms to RoHS directive requirements as stated in product information.

Typical Applications

• Automotive control circuits — Suited for vehicle control modules, including applications called out for the UBY series such as electric power steering and direct injection engine drive.
• High-temperature power systems — Filter and smoothing capacitor in power assemblies that operate at elevated ambient temperatures up to 135°C.
• Power electronics — DC link / decoupling and ripple suppression where high ripple current and low ESR are required.

Unique Advantages

• High ripple-current handling: Specified low- and high-frequency ripple currents (2.565 A at 120 Hz, 3.42 A at 100 kHz) support demanding AC ripple environments without excessive heating.
• Low loss operation: 22 mΩ ESR at 100 kHz minimizes I²R losses and improves efficiency in power stages and DC–DC converters.
• Extended high-temperature endurance: Rated 3000 hours at 135°C (25–50 V range), providing predictable life performance in hot operating conditions.
• Automotive-grade assurance: AEC-Q200 qualification and series-level recommendations for automobile control circuits provide design confidence for vehicle electronics.
• Compact radial format: φ16 × 40 mm radial can with 7.5 mm lead spacing provides a high-capacitance solution in a space-efficient package for through-hole assemblies.
