UBY1V392MHL6

The UBY1V392MHL6 is a miniature, high‑reliability aluminum electrolytic capacitor in a radial‑lead can, designed for demanding electronic control environments. It delivers 3.9 mF capacitance at 35 V with low ESR and high ripple current capability, and is intended for automotive control circuitry and other high‑temperature applications.

Built to the UBY series specification, this component combines high capacitance density, wide operating temperature range and extended endurance to support power smoothing and pulse‑load requirements in vehicle electronics and similar systems.

Key Features

• Electrical Performance: 3.9 mF capacitance rated at 35 V with a capacitance tolerance of −20% to +20% and a dissipation factor (tan δ) of 0.16 (20°C, 120 Hz).
• Low Impedance / Low ESR: ESR of 25 mΩ measured at 20°C and 100 kHz supports lower loss and improved stability under high frequency ripple conditions.
• High Ripple Capability: Low‑frequency ripple current 2.175 A (120 Hz) and high‑frequency ripple current 2.9 A (100 kHz) for demanding power applications.
• Wide Temperature Range & Endurance: Rated for operation from −40°C to +135°C with an endurance of 3000 hours at elevated temperature (125°C/135°C conditions per series spec).
• Mechanical / Form Factor: Radial lead can, size φ18 × 25 mm (diameter × length), lead spacing 7.5 mm (±0.5 mm), available in bulk or bag packing.
• Polarized, AEC‑Q200 Qualified: Polar component with AEC‑Q200 rating and RoHS compliance for automotive and regulated applications.
• Leakage Current: Specified leakage current 4095 μA.

Typical Applications

• Electric power steering modules: Supports the high ripple and temperature demands of steering control circuits in automotive systems.
• Direct injection engine drive electronics: Designed for pulse‑current and high‑temperature operation found in fuel‑injection control circuits.
• Automobile control circuits and power electronics: Suitable for control modules that require AEC‑Q200 qualified capacitors with high ripple capacity and extended endurance.

Unique Advantages

• High ripple tolerance: Specified ripple currents of 2.175 A (120 Hz) and 2.9 A (100 kHz) reduce thermal stress in power lines and help maintain stable filtering under dynamic loads.
• Low ESR for efficient performance: 25 mΩ ESR at 100 kHz lowers loss and improves high‑frequency behavior in switching and converter circuits.
• Wide temperature and long endurance: Rated −40°C to +135°C with 3000‑hour endurance for sustained operation in elevated temperature environments.
• AEC‑Q200 and RoHS compliance: Meets automotive qualification and environmental requirements for regulated applications.
• Compact radial can footprint: φ18 × 25 mm size with 7.5 mm lead spacing provides a compact, serviceable form factor for through‑hole assemblies.
• Mass production availability: Supplied in bulk or bag packing with mass production status to support production volumes.
