UXY1V732MHW

The UXY1V732MHW is a miniature, radial-lead aluminum electrolytic capacitor designed for heavy-duty automotive electronics. It combines a compact radial can package and vibration-resistant construction with high ripple-current capability and wide temperature tolerance for demanding in-vehicle environments.

Built for high-temperature operation and long-term reliability, this capacitor is rated for up to 35 V and specified to operate from −40°C to 135°C, with a 3000 hour endurance at 135°C and AEC-Q200 qualification.

Key Features

• Capacitance & Voltage — 7.3 mF nominal capacitance at a rated voltage of 35 V with ±20% tolerance, providing bulk energy storage for power conditioning and decoupling.
• High-Temperature Endurance — Specified lifetime of 3000 hours at 135°C, enabling sustained operation in elevated-temperature applications.
• Low Impedance / High Ripple Handling — Low ESR of 19 mΩ (measured at 100 kHz) and rated ripple currents of 3.315 A at 120 Hz and 3.9 A at 100 kHz for effective filtering under high AC stress.
• Vibration-Resistant Construction — Anti-vibration structuring with verified vibration performance (10–2000 Hz, up to 1.5 mm or 392 m/s² (40G), 6 hours total) to withstand automotive mechanical stress.
• Wide Temperature Range — Operates from −40°C to 135°C to meet thermal demands of automotive electronics and other harsh environments.
• Radial Lead / Through-Hole Package — Radial lead, can-style package with 7.5 mm lead spacing and compact dimensions (L: 4 × D: 1.8 cm) for board-level power applications requiring through-hole mounting.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant, supporting regulatory and reliability needs for automotive applications.

Typical Applications

• Automotive electronics — Designed for heavy-duty in-vehicle systems that require high ripple-current filtering and durable performance across wide temperatures.
• Power supply filtering — Bulk energy storage and smoothing in power modules where low ESR and high ripple capability reduce voltage ripple and thermal stress.
• High-temperature environments — Energy storage and decoupling in electronics exposed to sustained elevated temperatures up to 135°C.

Unique Advantages

• High ripple tolerance: Rated ripple currents at both 120 Hz and 100 kHz (3.315 A and 3.9 A) let designers address a wide range of switching and low-frequency disturbances.
• Low ESR: 19 mΩ at 100 kHz minimizes power loss and heat generation, improving efficiency and thermal margin in power circuits.
• Vibration-hardened: Anti-vibration structure and qualified vibration test conditions reduce risk of mechanical failure in mobile and vibration-prone installations.
• High-temperature lifetime: 3000 hours at 135°C provides predictable endurance for designs that must maintain performance in hot environments.
• AEC-Q200 qualified & RoHS compliant: Simplifies compliance for automotive designs and supports regulatory requirements for manufacturing and deployment.
• Compact through-hole package: Radial lead can with 7.5 mm lead spacing and small footprint (L: 4 × D: 1.8 cm) eases mechanical integration where board real estate is constrained.
