UPM1A392MHD6

The UPM1A392MHD6 is an aluminum electrolytic capacitor from Nichicon's UPM series. It delivers 3.9 mF capacitance at 10 V in a radial-lead can (φ18 × 20L) with 7.5 mm lead spacing.

Engineered for demanding environments, this capacitor offers low impedance, high ripple-current capability and long endurance—making it suitable for automotive electronics and other applications that require stable performance across −55 °C to 105 °C and 5,000 hours of rated-life at 105 °C.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a rated voltage of 10 V and capacitance tolerance of ±20%.
• Low Impedance — Rated impedance of 28 mΩ for reduced voltage ripple and improved dynamic response in power circuits.
• High Ripple Current Capability — Supports 2.852 A at 120 Hz (low frequency) and 1.84 A at 200 kHz (high frequency) to handle demanding AC ripple conditions.
• Loss Characteristics — tan δ = 0.19 measured at 20 °C, 120 Hz, enabling predictable dissipation behavior for thermal and reliability assessments.
• Leakage Current — Specified leakage current of 1170 µA for predictable bias behavior after voltage application.
• Long Endurance — Rated life of 5,000 hours at 105 °C under rated DC bias plus ripple, supporting sustained operation in high-temperature environments.
• Robust Temperature Range — Operates from −55 °C to 105 °C for broad environmental coverage.
• Automotive-Grade Qualification — AEC-Q200 rated, suitable for automotive electronics designs.
• Package & Mounting — Radial lead can (φ18 × 20L) with 7.5 mm lead spacing (±0.5 mm), packaged bulk/no terminal forming or bag packing for flexible assembly.
• Compliance — RoHS compliant.

Typical Applications

• Automotive power electronics — Bulk smoothing and decoupling where high ripple current handling and elevated temperature endurance are required.
• Control modules and ECUs — Local energy storage and stable biasing in modules that must withstand −55 °C to 105 °C and long operating life.
• Energy buffering and power conditioning — Provides 3.9 mF at 10 V for transient energy delivery and ripple absorption in constrained board space.

Unique Advantages

• High ripple tolerance: Dual rated ripple currents (2.852 A at 120 Hz, 1.84 A at 200 kHz) let designers manage both low- and high-frequency ripple without overspecifying parts.
• Long high-temperature life: 5,000-hour endurance at 105 °C supports prolonged operation in hot operating environments and helps extend system service life.
• Low impedance for compact power designs: 28 mΩ impedance reduces voltage droop and supports tighter power-supply decoupling in compact layouts.
• Automotive qualification: AEC-Q200 rating aligns the component with automotive reliability expectations for vehicle electronics.
• Predictable thermal and loss behavior: Specified tan δ (0.19 at 20 °C, 120 Hz) provides measurable loss characteristics for thermal budgeting and verification.
• Easy integration: Radial lead can with 7.5 mm lead spacing and standard sleeve marking simplifies mechanical assembly and identification.
