UXY1E782MHW

The UXY1E782MHW is a radial‑lead aluminum electrolytic capacitor from Nichicon’s UXY series designed for high‑temperature, vibration‑resistant applications. It is a polarized, low‑impedance can‑type capacitor specified at 7.8 mF (7,800 μF) and 25 V, intended for heavy‑duty electronics that require high ripple handling and long endurance at elevated temperatures.

Key value propositions include AEC‑Q200 qualification, RoHS compliance, proven endurance at 125 °C / 135 °C (3,000 hours), and construction optimized for vibration resistance relative to the UBY series.

Key Features

• Capacitance & Voltage — 7.8 mF (7,800 μF) rated at 25 V with ±20% tolerance, providing bulk energy storage for power conditioning.
• High‑temperature Endurance — Rated for operation from −40 °C to +135 °C with a specified endurance of 3,000 hours at 125 °C / 135 °C.
• Low ESR & Ripple Handling — Equivalent series resistance of 23 mΩ at 100 kHz, with ripple current ratings of 2.83 A at 120 Hz and 3.33 A at 100 kHz for robust ripple dissipation.
• Vibration‑resistant Construction — Anti‑vibration structuring vs. UBY series and tested under vibration conditions (10–2000 Hz, total amplitude 1.5 mm or 392 m/s² (40G) whichever is looser) to retain electrical characteristics after mechanical stress.
• AEC‑Q200 Qualified & RoHS Compliant — Meets AEC‑Q200 qualification and complies with the RoHS directive (2011/65/EU, (EU)2015/863), supporting regulated and quality‑driven designs.
• Radial‑lead, Can Package — Radial lead mounting with 7.5 mm lead spacing in a compact can form factor (L: 3.05 × D: 1.8 cm) for through‑hole assembly.

Typical Applications

• Automotive electronics — Suited for automobile electronics where heavy‑duty service is indispensable; ideal where high temperature endurance and vibration resistance are required.
• Power supply smoothing and decoupling — Bulk energy storage and ripple dissipation for modules exposed to high ripple currents and elevated ambient temperatures.
• Vibration‑prone embedded systems — Use in electronic modules subjected to mechanical vibration, leveraging the series’ anti‑vibration structuring and qualification.

Unique Advantages

• Long high‑temperature lifetime: 3,000 hours rated endurance at 125 °C / 135 °C provides predictable performance for designs targeting elevated operating temperatures.
• Measured low ESR: 23 mΩ at 100 kHz reduces heat generation and supports higher ripple currents for improved power integrity.
• Designed for vibration resistance: Construction and testing across 10–2000 Hz and up to 40G validate stability of capacitance, tan δ, and leakage after mechanical stress.
• Automotive‑grade qualification: AEC‑Q200 status supports use in regulated automotive and similarly demanding markets.
• Compact radial package: Can‑type radial lead form with 7.5 mm lead spacing and a small L×D footprint simplifies board layout for through‑hole assemblies.
• Regulatory readiness: RoHS compliance ensures compatibility with environmental directives and restricted substance requirements.
