UPW0J392MHD

The UPW0J392MHD is a miniature aluminum electrolytic capacitor from Nichicon's UPW series, engineered for switching power supply applications. It combines a compact radial-can package and radial lead mounting with low impedance and automotive‑grade reliability for demanding power environments.

Targeted for systems that require robust bulk capacitance and ripple handling in constrained spaces, this part delivers measurable ripple current capability, a wide operating temperature range, and AEC‑Q200 qualification for automotive applications.

Key Features

• Capacitance & Voltage — 3.9 mF capacitance rated at 6.3 V with ±20% tolerance, suitable for bulk energy storage and decoupling in low‑voltage power rails.
• Low Impedance — 60 mΩ impedance to reduce voltage ripple and support tighter power regulation.
• Ripple Current Capability — Rated for 1.653 A at 120 Hz and 1.945 A at 10 kHz, enabling effective smoothing across typical switching frequencies.
• Temperature & Lifetime — Operating temperature range of −55°C to +105°C with a rated lifetime of 7000 hours at 105°C.
• Package & Mounting — Radial can package with radial lead mounting and 5 mm lead spacing for through‑hole assembly and secure mechanical retention.
• Qualification — AEC‑Q200 rated for use in automotive applications requiring that qualification.
• Form Factor — Compact size (L: 2.5 × D: 1.25 cm) to fit space‑constrained PCB layouts.

Typical Applications

• Switching Power Supplies — Bulk and smoothing capacitance for power stages where low impedance and reliable ripple handling improve regulation.
• Automotive Electronics — AEC‑Q200 qualification and wide temperature range make it suitable for automotive power modules and control systems.
• DC–DC Converters — Fits compact converters requiring stable capacitance and measurable ripple current at audio and switching frequencies.

Unique Advantages

• Compact energy density: 3.9 mF capacitance in a small radial can footprint helps reduce board area for bulk energy storage.
• Measured low impedance: 60 mΩ impedance supports lower output ripple and improved transient response in switching stages.
• Frequency‑proven ripple capability: Specified ripple current at both 120 Hz and 10 kHz lets designers quantify performance across common switching bands.
• Automotive‑grade reliability: AEC‑Q200 rating and a 7000‑hour life at 105°C provide predictable longevity for vehicle systems.
• Through‑hole robustness: Radial lead mounting with 5 mm lead spacing simplifies assembly and improves mechanical durability.
