UPJ1K121MHD6

The UPJ1K121MHD6 is a Nichicon UPJ series aluminum electrolytic capacitor in a radial-lead can, specified at 120 µF and 80 V with ±20% tolerance. Designed for low-impedance power applications, this component targets switching power supplies and general-purpose power filtering where long life, stable performance and compact radial packaging are required.

Key Features

• Electrical Performance — 120 µF nominal capacitance at 80 V rated voltage with ±20% tolerance, providing bulk energy storage and smoothing for power rails.
• Low Impedance — Part of the UPJ series specified for low impedance, making it suitable for use in switching power supplies and other high-frequency power circuits.
• Loss and Leakage — Low loss tangent (tanδ 0.08) and specified leakage current of 288 µA, supporting predictable dissipation and steady-state behavior under rated conditions.
• Ripple Current Capability — Rated ripple currents of 235.3 mA at 120 Hz and 444 mA at 200 kHz to support AC ripple handling across a wide frequency range.
• Thermal and Lifetime Reliability — Rated for operation from −55°C to +105°C with a 5000-hour load life at 105°C, delivering durability in elevated-temperature environments.
• Package and Mounting — Radial-lead can construction (φ16 × 15 mm) with 7.5 mm lead spacing for through-hole assemblies; bulk/bag packing for mass production handling.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low impedance and rated ripple current make this capacitor well suited for smoothing and decoupling in switching regulators and power conversion stages.
• General-Purpose Power Filtering — Bulk energy storage and ripple suppression in DC power rails for industrial and electronic equipment.
• Power Management Circuits — Energy buffering and transient handling in DC-DC converters and auxiliary power circuits where a compact radial electrolytic is preferred.

Unique Advantages

• Balanced capacitance and voltage rating — 120 µF at 80 V provides a useful combination for mid-voltage power rails without exceeding the size constraints of a φ16 can.
• Designed for switching environments — Low impedance characteristics and high-frequency ripple ratings support performance in switching applications.
• High-temperature endurance — 5000 hours at 105°C enables longer service life in thermally demanding installations.
• Predictable electrical behavior — Specified tanδ and leakage current allow engineers to model dissipation and leakage in power designs accurately.
• Production-ready packaging — Bulk/bag packing supports high-volume assembly and procurement workflows.
• RoHS compliance — Meets regulatory restrictions on hazardous substances for broad market deployment.
