UBY1H132MHL

The UBY1H132MHL is a radial-lead aluminum electrolytic capacitor from Nichicon’s UBY series, offering 1.3 mF capacitance at a 50 V rating. It is designed for demanding environments with a wide operating temperature range and high ripple-handling capability, making it suitable for automotive and other high-reliability power applications.

Key value propositions include high ripple current and low ESR for improved power smoothing, a long endurance rating at elevated temperatures, and AEC-Q200 qualification and RoHS compliance for regulated designs.

Key Features

• Capacitance & Voltage — 1,300 µF (±20%) rated at 50 V for bulk energy storage and decoupling in mid-voltage power rails.
• High Temperature Operation — Rated operating range from −40°C to +135°C to support elevated ambient conditions.
• High Ripple Current — Low-frequency ripple current 1.668 A (120 Hz) and high-frequency ripple current 2.78 A (100 kHz) to handle dynamic load currents.
• Low ESR — Equivalent series resistance 33 mΩ at 20°C/100 kHz for reduced power loss and improved thermal performance.
• Endurance — 3,000 hours life under specified endurance conditions (DC bias plus rated ripple current at elevated temperature), supporting reliable long-term operation.
• Form Factor — Compact radial can: φ12.5 × 35.5 mm with 5.0 mm lead spacing (lead spacing tolerance ±0.5 mm), supplied bulk/bag packaging for through-hole assembly.
• Compliance & Qualification — AEC-Q200 qualified and RoHS compliant for regulated and automotive-grade designs.
• Polarized, Radial-Lead Package — Straight radial-lead mounting for easy placement in through-hole and serviceable power electronics assemblies.

Typical Applications

• Automotive control circuits — Suited for power management in automobile control modules such as electric power steering and direct injection engine drive, where high ripple tolerance and high-temperature endurance are required.
• Power supply filtering — Bulk energy storage and smoothing on DC rails in power converters and regulators that demand low ESR and high ripple capability.
• Engine and power electronics — Local decoupling in motor drives, actuators, and other high-current subsystems operating over wide temperature ranges.

Unique Advantages

• High ripple-handling capability — Specified ripple currents at both low and high frequencies reduce thermal stress and improve lifetime under dynamic loads.
• Low ESR for efficiency — 33 mΩ ESR at 100 kHz minimizes I²R losses and supports more efficient power conversion and thermal performance.
• Long high-temperature endurance — 3,000 hours rated life under endurance test conditions at elevated temperature, enabling sustained operation in harsh environments.
• Automotive-grade qualification — AEC-Q200 qualification provides assurance for use in regulated automotive electronics designs.
• Compact radial can — Small φ12.5 × 35.5 mm package with standard 5 mm lead spacing simplifies integration into space-constrained through-hole layouts.
• Regulatory compliance — RoHS compliant to meet environmental requirements in modern electronics production.
