UPA1V182MHD6

The UPA1V182MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPA series. It is a radial-lead, polarized can-type capacitor specified for power filtering and smoothing in compact power designs.

Designed for switching power supplies and general-purpose power applications, this part offers low impedance, high ripple-current capability and extended endurance at elevated temperature to support demanding power-rail requirements.

Key Features

• Capacitance & Voltage: 1.8 mF (1800 µF) rated at 35 V with a capacitance tolerance of −20% to +20%.
• Low Impedance: Rated impedance of 52 mΩ to reduce voltage ripple and improve transient response; UPA series is specified as lower impedance than UPW.
• High Ripple-Current Handling: Low-frequency ripple current 1.98 A (120 Hz) and high-frequency ripple current 2.33 A (10 kHz) for effective smoothing across frequencies.
• Dissipation Factor (tan δ): tanδ = 0.12 (measured at 35 V, 120 Hz, 20°C), suitable for power applications requiring controlled losses.
• Leakage Current: Specified leakage current of 1890 µA.
• Thermal & Lifetime Performance: Operating temperature range −55°C to +105°C with rated endurance of 5000 hours at 105°C.
• Package & Mounting: Radial lead can, size φ16 × 20L, lead spacing 7.5 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Polarized, General-Purpose: Polarized aluminum electrolytic design targeted at general-purpose power applications.

Typical Applications

• Switching Power Supplies: Bulk and output filtering where low impedance and high ripple-current capability reduce voltage ripple and improve regulation.
• DC–DC Converters and Power Rails: Local decoupling and energy storage for converters that require compact, high-capacitance components.
• Industrial Power Electronics: Filtering and smoothing on control and power boards exposed to wide ambient temperatures and continuous duty.
• General-Purpose Electronic Equipment: Power smoothing and ripple reduction in consumer and commercial devices that use radial-lead capacitors.

Unique Advantages

• Space-efficient, high-capacitance package: φ16 × 20L footprint delivers 1800 µF in a compact radial-lead can for space-constrained boards.
• Superior ripple performance: High allowable ripple currents at both low and high frequencies (1.98 A at 120 Hz, 2.33 A at 10 kHz) support stable power delivery across operating conditions.
• Low ESR/impedance: 52 mΩ impedance helps minimize power loss and voltage drop under load, improving converter efficiency and transient response.
• Extended high-temperature endurance: Rated for 5000 hours at 105°C, enabling reliable operation in thermally demanding environments.
• Wide operating temperature range: −55°C to +105°C supports applications across a broad set of environmental conditions.
• Series-level quality: UPA series characteristics such as lower impedance than UPW and RoHS compliance provide clear selection benefits for power designs.
