UPJ1V182MHD

The UPJ1V182MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a radial-lead, polarized can-style capacitor specified at 1,800 µF and 35 V, designed with low impedance characteristics that suit power conversion and general-purpose electronic applications.

Key attributes include a long rated endurance at elevated temperature, measurable low- and high-frequency ripple current capabilities, and compact radial packaging for through-hole mounting and replacement designs.

Key Features

• Capacitance & Voltage: 1,800 µF nominal capacitance with a rated voltage of 35 V and a tolerance of −20% to +20%.
• Low Impedance Design: UPJ series low-impedance construction with a tangent of loss angle (tanδ) of 0.12 measured at 20°C, 120 Hz for 35 V units, supporting efficient filtering in switching environments.
• High Temperature Endurance: Rated for 5,000 hours of load life at +105°C (per series specification), supporting sustained operation in elevated-temperature installations.
• Ripple Current Handling: Low-frequency ripple current 1.998 A at 120 Hz and high-frequency ripple current 2.22 A at 200 kHz, enabling reliable smoothing under dynamic loads.
• Leakage Current: Specified leakage current of 1,890 µA (measured conditions per product data), allowing predictable bias behavior in power circuits.
• Operating Range: Wide operating temperature from −55°C to +105°C to cover a broad range of environmental conditions.
• Package & Mounting: Radial lead (can) package, size Ø16 × 30.5 mm (L: 3.05 × D: 1.6 cm), lead spacing 7.5 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Compliance: RoHS-compliant material status as provided in the product data.

Typical Applications

• Switching Power Supplies: Low-impedance behavior and rated ripple-current capability make this capacitor suitable for bulk smoothing and decoupling in switch-mode power supplies.
• General-Purpose Electronics: Provides bulk capacitance for power rails and energy storage in a variety of through-hole designs classified as general purpose.
• High-Temperature Installations: Long endurance at +105°C supports use where sustained elevated temperature performance is required by the design.

Unique Advantages

• Designed for low impedance: tanδ specification and UPJ series construction reduce AC losses, supporting efficient filtering in dynamic power circuits.
• High ripple current capability: Specified LF and HF ripple currents (1.998 A at 120 Hz and 2.22 A at 200 kHz) enable handling of both mains-frequency and switching-domain ripple.
• Extended high-temperature life: 5,000-hour endurance at +105°C provides documented longevity for sustained thermal stress.
• Compact radial form factor: Ø16 × 30.5 mm can with 7.5 mm lead spacing fits common through-hole layouts and replacement footprints.
• Predictable leakage behavior: Specified leakage current (1,890 µA) allows designers to budget standby and bias currents accurately.
• RoHS compliance: Material compliance simplifies regulatory tracking for assemblies.
