UBY1V392MHL

The UBY1V392MHL is a miniature aluminum electrolytic capacitor from Nichicon’s UBY series designed for high-reliability applications. It is a radial-lead, can-style polarized capacitor specified at 3.9 mF and 35 V with a compact footprint suited to space‑constrained power circuits.

Engineered for demanding operating environments, this capacitor combines low equivalent series resistance and high ripple-current capability with AEC‑Q200 qualification and RoHS compliance, making it appropriate for automotive and other high-temperature electronics.

Key Features

• Capacitance & Voltage: 3.9 mF (3,900 µF) rated at 35 V with ±20% tolerance, providing bulk energy storage and smoothing for DC power rails.
• Low ESR: 23 mΩ equivalent series resistance measured at 100 kHz, supporting lower losses and improved efficiency in high-frequency circuits.
• High Ripple Current: Rated ripple currents of 2.55 A at 120 Hz and 3.4 A at 100 kHz, suited for circuits with significant AC or switching ripple.
• Wide Temperature Range & Endurance: Operating temperature −40 °C to +135 °C with endurance specified at 3,000 hours at 135 °C under rated conditions.
• Reliability & Compliance: AEC‑Q200 qualified and RoHS compliant, targeted for high-reliability and regulated environments.
• Package & Mounting: Radial lead, can-style package with 7.5 mm lead spacing and compact dimensions (L: 3.05 × D: 1.6 cm) for through‑hole PCB mounting.

Typical Applications

• Automotive control circuits: Suitable for vehicle control modules such as electric power steering and direct injection engine drive where high ripple handling and high-temperature endurance are required.
• High-ripple power electronics: Bulk smoothing and decoupling in DC-DC converters and motor drive circuits that generate substantial ripple current.
• In-vehicle electronics: Energy storage and transient suppression for electronic control units operating across wide temperature ranges.

Unique Advantages

• High ripple-current capability: Supports elevated AC and switching currents (3.4 A at 100 kHz), reducing thermal stress in ripple-heavy circuits.
• Low loss at high frequency: 23 mΩ ESR at 100 kHz minimizes power dissipation and improves efficiency in high-frequency power stages.
• High-temperature endurance: Rated for operation to +135 °C with 3,000-hour endurance, enabling reliable performance in elevated-temperature environments.
• AEC‑Q200 qualification: Meets automotive-grade reliability requirements, providing traceable quality for vehicle electronics projects.
• Compact radial-can form factor: Small footprint and radial lead mounting simplify replacement of legacy through-hole capacitors while preserving mechanical robustness.
• Regulatory compliance: RoHS compliant for environmentally regulated designs.
