UPJ0J392MHD

The UPJ0J392MHD is a miniature, high‑reliability aluminum electrolytic capacitor in a radial‑lead can designed for power applications. It delivers low impedance and elevated ripple handling for demanding DC‑DC and switching power supply environments.

With 3.9 mF capacitance at 6.3 V, a wide operating range from −55 °C to +105 °C, and a rated endurance of 5000 hours at 105 °C, this part is targeted at general‑purpose power filtering and decoupling where long life and robust ripple performance matter.

Key Features

• Low‑impedance construction — Designed for switching power supplies and other power conversion circuits to minimize voltage ripple and improve transient response.
• Capacitance and voltage — 3.9 mF (3900 µF) nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20% to support bulk energy storage and smoothing.
• High ripple current capability — Low‑frequency ripple current of 1.539 A at 120 Hz and high‑frequency ripple current of 1.71 A at 200 kHz, enabling reliable operation under significant AC stress.
• Measured dissipation factor — tan δ = 0.26 measured at 20 °C, 120 Hz and 6.3 V, for predictable AC loss characteristics in design calculations.
• Extended endurance at elevated temperature — Rated for 5000 hours at +105 °C, supporting long service life in high‑temperature systems.
• Compact radial can package — Physical size φ12.5 × 30.5 mm with 5.0 mm lead spacing (±0.5 mm) and lead diameter 0.8 mm for L > 25 mm, simplifying board placement in constrained layouts.
• Polarized, general‑purpose device — Radial lead, polarized aluminum electrolytic suitable for standard power‑supply topologies.
• Regulatory compliance — RoHS compliant.
• Packaging and availability — Supplied in bulk (no terminal forming) or bag packing; product status: mass production.

Typical Applications

• Switching power supplies — Bulk smoothing and output filtering where low impedance and high ripple endurance are required.
• Power supply filtering and decoupling — Energy storage and ripple suppression in DC‑DC converters and regulator output stages.
• High‑temperature power modules — Circuits operating up to +105 °C that require extended endurance (5000 h) under bias and ripple.

Unique Advantages

• Designed for long life at elevated temperature: 5000‑hour endurance at +105 °C provides predictable lifetime performance in hot operating environments.
• Strong ripple handling across frequencies: Specified ripple currents at 120 Hz and 200 kHz permit confident selection for both low‑ and high‑frequency power systems.
• Compact can‑style form factor: φ12.5 × 30.5 mm radial can offers a small footprint for space‑constrained power boards while preserving capacitance.
• Measured dissipation factor for design tightness: tan δ specified at measurement conditions helps engineers estimate thermal and loss behavior under operating bias.
• RoHS compliance and production readiness: Environmentally compliant and available in mass production packaging options to support volume manufacturing.
