UPJ1H181MHD6

The UPJ1H181MHD6 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPJ series. It is a radial-lead, polar capacitor specified at 180 µF and 50 V, designed for general-purpose electronics and switching power supply applications.

Key value comes from its low-impedance construction, extended load life (5000 hours at 105°C), and compact φ12.5 × 15 mm can – delivering reliable smoothing and decoupling in space-constrained power designs.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a rated voltage of 50 V and tolerance of -20% to +20% (measured at 20°C, 120 Hz).
• Low Loss — tanδ (DF) of 0.10 (measured at 20°C, 120 Hz) for reduced dissipation and improved performance in AC ripple environments.
• Ripple Current Capability — Low-frequency ripple current 326.7 mA at 120 Hz and high-frequency ripple current 605 mA at 200 kHz for power supply smoothing and decoupling tasks.
• Leakage Current — Specified leakage current of 270 µA after rated voltage application, supporting reliable biasing and low standby drain.
• High Reliability / Long Life — Endurance rated 5000 hours at 105°C under specified load conditions for sustained operation in elevated-temperature environments.
• Temperature Range — Operates from -55°C to +105°C, suitable for a wide range of environmental conditions.
• Compact Radial Package — Can dimensions φ12.5 × 15 mm with 5.0 mm lead spacing (±0.5 mm); radial lead mounting for through-hole assembly.
• Polarized, Radial-Lead Form — Intended for polar applications and general-purpose power electronics; packaging available in bulk or bag (no terminal forming).
• Regulatory Status — RoHS compliant; part is in mass production.

Typical Applications

• Switching Power Supplies — Output smoothing and decoupling where low impedance and long endurance improve voltage stability under ripple stress.
• General-Purpose Power Electronics — Bulk filtering and local decoupling in power rails for industrial and consumer electronic equipment.
• Embedded Systems — Decoupling and energy buffering in compact, through-hole PCB assemblies that require a reliable radial electrolytic solution.

Unique Advantages

• Low-impedance performance: Tangent of loss angle (tanδ) of 0.10 at 20°C/120 Hz reduces power dissipation and improves AC performance in ripple-heavy circuits.
• Extended high-temperature life: Rated for 5000 hours at 105°C, providing predictable aging characteristics for designs exposed to elevated operating temperatures.
• Measured ripple handling: Specified ripple current values at both 120 Hz and 200 kHz give designers concrete limits for thermal and ripple budgeting.
• Compact through-hole package: φ12.5 × 15 mm can with 5.0 mm lead spacing fits space-constrained PCBs while retaining robust radial-lead mounting.
• Low standby leakage: 270 µA leakage current supports lower quiescent drain in powered systems.
• Production-ready supply: Mass production status and standard bulk/bag packing options simplify procurement and assembly planning.
