UPJ1H182MHD

The UPJ1H182MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, offering 1.8 mF (1800 µF) capacitance at a 50 V rating. It is a low-impedance, high-reliability component designed for general-purpose power applications and switching power supplies.

Key characteristics include a wide operating temperature range of −55 °C to +105 °C, a rated load life of 5000 hours at 105 °C, and form-factor conveniences such as a φ18 × 35.5 mm can with 7.5 mm lead spacing for through-hole mounting.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) nominal capacitance with a 50 V rated voltage and ±20% tolerance for bulk energy storage and decoupling.
• Low Dissipation Factor — tanδ = 0.10 measured at 20 °C, 120 Hz, 50 V, supporting efficient filtering with reduced losses.
• High Ripple Current Capability — Low-frequency ripple current of 1.989 A (120 Hz) and high-frequency ripple current of 2.21 A (200 kHz) to handle dynamic power supply currents.
• Long Endurance at Elevated Temperature — Rated for 5000 hours at +105 °C under rated DC bias plus ripple current, reflecting series-level long-life performance.
• Wide Temperature Range — Operates across −55 °C to +105 °C for a broad set of environmental conditions.
• Through-Hole Radial Package — φ18 × 35.5 mm can, 7.5 mm lead spacing (±0.5 mm), radial lead mounting for standard PCB assembly and prototyping workflows.
• Leakage Current — Specified leakage current of 2700 µA for predictable bias behavior after application of rated voltage.
• Regulatory — RoHS compliant.
• Availability — Mass production status; packaged in bulk (no terminal forming) or bag packing options.

Typical Applications

• Switching Power Supplies — Low-impedance design and specified ripple current values support bulk filtering and output smoothing in DC-DC converters and SMPS circuits.
• General Purpose Power Filtering — Suited for bulk decoupling and energy storage in a wide range of electronics requiring a 50 V, 1800 µF capacitor.
• Industrial Power Modules — High endurance at 105 °C and wide operating temperature range make it appropriate for industrial power electronics where long life is required.

Unique Advantages

• High ripple current handling: Rated ripple currents at both low and high frequencies (1.989 A at 120 Hz, 2.21 A at 200 kHz) enable reliable performance under dynamic load conditions.
• Extended high-temperature life: 5000 hours endurance at +105 °C provides predictable aging characteristics for designs requiring long-term stability.
• Low dissipation losses: tanδ of 0.10 at 20 °C and 120 Hz reduces power loss and heating in filtering applications.
• Robust temperature range: −55 °C to +105 °C operation supports deployment across wide environmental conditions.
• Through-hole convenience: Radial-lead can (φ18 × 35.5 mm) with 7.5 mm lead spacing simplifies prototyping and legacy PCB integration.
• Regulatory compliance and production readiness: RoHS compliant and listed as mass production, easing procurement and regulatory checks.
