UHV1A182MPD

The UHV1A182MPD is a radial-leaded aluminum electrolytic capacitor in Nichicon’s UHV series designed for general-purpose power applications that require high ripple handling and low impedance. It combines a compact φ10×20 mm can with a 1.8 mF, 10 V rating and polarization for DC applications.

With a rated operating range of −40°C to +105°C and a 6000‑hour endurance at 105°C, this part targets power-supply filtering, DC/DC converter smoothing and other applications that benefit from high ripple capacity and stable performance over temperature and time.

Key Features

• Electrical Capacity — 1.8 mF (1800 µF) capacitance at 10 VRated with ±20% tolerance, suitable for bulk filtering and energy storage in compact assemblies.
• Low Impedance — Rated impedance of 57 mΩ supports lower voltage ripple under load and improved high-frequency performance in power circuits.
• High Ripple Current — Supports 1.296 A at 120 Hz and 2.16 A at 100 kHz (rated ripple currents), enabling robust smoothing for both low- and high-frequency switching environments.
• Controlled Dissipation Factor — tanδ specified as 0.18 (20°C, 120 Hz), providing predictable loss characteristics for thermal and efficiency considerations.
• Leakage & Polarization — Polarized design with leakage current of 180 µA (after standard test conditions), suitable for DC filter applications where leakage is a known parameter.
• Reliability & Lifetime — 6000 hours endurance at 105°C under rated conditions; designed for sustained operation in elevated-temperature environments.
• Mechanical & Mounting — Radial lead can, φ10×20 mm case size with 5 mm lead spacing, packaged in bulk/bag packing for through‑hole assembly and hand or machine insertion.
• Environmental Compliance — RoHS‑compliant construction.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling on DC rails for linear and switching supplies where high ripple current capability reduces output ripple.
• DC/DC Converter Output — Energy storage and output stabilization for converters operating at both low and high switching frequencies thanks to the specified ripple current at 120 Hz and 100 kHz.
• Input Ripple Suppression — Input filtering on power modules and adapters to absorb switching-generated ripple and reduce stress on downstream circuitry.
• General-Purpose Energy Hold-Up — Short-term energy buffering and smoothing in consumer and industrial electronics where a compact radial can is preferred.

Unique Advantages

• Compact, high‑capacitance package — φ10×20 mm can delivers 1800 µF in a small through‑hole footprint for space-constrained board layouts.
• High-frequency performance — Low impedance and specified ripple currents at 100 kHz help maintain filtering effectiveness in modern high-speed switching environments.
• Thermal endurance — 6000 h at 105°C rating provides predictable lifetime for elevated-temperature applications and long-term reliability planning.
• Predictable loss and leakage — Specified tanδ and leakage current values allow designers to model dissipation and standby currents accurately.
• Through-hole robustness — Radial lead package with 5 mm lead spacing simplifies mechanical mounting and is compatible with manual and wave-solder assembly processes.
