UHV1E182MHD

The UHV1E182MHD is a radial-lead aluminum electrolytic capacitor designed for general-purpose applications requiring high capacitance and robust ripple-handling in a compact can. It delivers 1.8 mF at 25 V with low impedance characteristics targeted at improved performance across higher frequencies.

Built for durability in demanding thermal environments, this component is specified for operation from −40°C to 105°C and rated for 6000 hours of endurance at 105°C, offering reliable long-term performance in designs that require sustained ripple current capability.

Key Features

• Electrical Capacity — 1.8 mF (1800 µF) nominal capacitance with tolerance ±20% for bulk energy storage and decoupling.
• Rated Voltage — 25 V DC rated voltage suitable for a wide range of low-voltage power rails.
• Low Impedance — Characteristic impedance of 36 mΩ supports improved high-frequency performance and reduced voltage ripple.
• High Ripple Current — Low-frequency ripple current 1.914 A (120 Hz) and high-frequency ripple current 3.19 A (100 kHz) for applications with significant AC content.
• Long Endurance — Lifetime: 6000 hours at 105°C under rated conditions, with specified limits for capacitance change, tan δ, and leakage current after endurance testing.
• Wide Temperature Range — Rated for operation from −40°C to 105°C to cover a broad range of environmental conditions.
• Compact Radial Can — Case size φ12.5 × 25 mm with 5.0 mm lead spacing (tolerance ±0.5 mm), radial lead mounting for through-hole assemblies.
• Leakage and Dissipation — Specified leakage current of 450 µA and tan δ (DF) of 0.13 at 20°C, 120 Hz for predictable loss characteristics.
• Compliance — RoHS compliant.

Typical Applications

• General-purpose power modules — Suited to circuits that require 1.8 mF bulk capacitance and robust ripple handling up to 3.19 A at high frequency.
• High-frequency decoupling — Low impedance and defined tan δ make it useful where improved AC performance at higher frequencies is required.
• Thermally demanding systems — Specified 6000 h life at 105°C for designs that must withstand extended elevated-temperature operation.

Unique Advantages

• High ripple capability: Rated ripple currents of 1.914 A (120 Hz) and 3.19 A (100 kHz) reduce heating and extend service life in AC-loaded circuits.
• Low impedance at frequency: 36 mΩ impedance supports improved voltage stability and reduced ESR-related losses at higher frequencies.
• Durable long-life rating: 6000 hours at 105°C provides predictable endurance for long-term deployments.
• Compact through-hole form factor: φ12.5 × 25 mm radial can with 5 mm lead spacing conserves board area while enabling conventional through-hole assembly.
• Controlled leakage and dissipation: Leakage current of 450 µA and tan δ 0.13 (20°C, 120 Hz) help maintain predictable performance in sensitive power designs.
• RoHS compliant and production-ready: Compliant to RoHS and available in mass production packaging options (bulk / bag packing).
