UPW1E392MHD6

The UPW1E392MHD6 is a Nichicon UPW series aluminum electrolytic capacitor in a miniature radial‑lead can designed for low impedance and high reliability. It provides 3.9 mF capacitance at a 25 V rating with a compact φ18 × 30.5 mm footprint and 7.5 mm lead spacing.

Targeted for switching power supplies and demanding electronic systems, this part delivers elevated ripple current capability and extended endurance for applications requiring sustained operation at elevated temperature.

Key Features

• Capacitance & Voltage — 3900 µF (3.9 mF) capacitance rated at 25 V, with tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 32 mΩ supporting lower ripple and improved transient response in power circuits.
• High Ripple Current Handling — Low‑frequency ripple current 3.08975 A (at 120 Hz) and high‑frequency ripple current 3.635 A (at 10 kHz) to support heavy filtering and smoothing duties.
• Long Endurance — Rated life of 8000 hours at 105°C, providing long service life under high‑temperature stress.
• Wide Temperature Range — Operating range from −55°C to +105°C for use in harsh thermal environments.
• Electrical Loss (tan δ) — tan δ ≈ 0.18 measured at 20°C, 120 Hz, for predictable loss characteristics in AC conditions.
• Package & Mounting — Radial lead, can‑style package (φ18 × 30.5L) with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• AEC‑Q200 Rated — Conforms to AEC‑Q200 reliability requirements as specified in the product data.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where high ripple current capability and low impedance reduce voltage ripple and improve regulator stability.
• Automotive Electronics — Suitable for automotive electronic modules that require AEC‑Q200 qualified capacitors with long endurance at elevated temperature.
• Power Conditioning in Compact Designs — Small φ18 footprint and radial lead format enable use in constrained board areas requiring high capacitance.

Unique Advantages

• High ripple tolerance: Allows designers to handle substantial AC stress at both low and high frequencies, reducing the need for oversized capacitor arrays.
• Low ESR/Impedance: 32 mΩ impedance helps lower power loss and voltage ripple in power delivery networks.
• Extended high‑temperature life: 8000 hours at 105°C supports reliable long‑term operation in thermally challenging environments.
• Automotive‑grade reliability: AEC‑Q200 rating signals suitability for applications that require an established automotive reliability standard.
• Compact radial can package: φ18 × 30.5 mm size with 7.5 mm lead spacing balances high capacitance with a small board footprint and easy through‑hole mounting.
• Ready for production: Listed as mass production with bulk and bag packing options for easy integration into manufacturing workflows.
