UHD1E182MHD

The UHD1E182MHD is an aluminum electrolytic capacitor in a radial-lead can, rated at 1800 µF and 25 V, designed for general-purpose electronic applications. It delivers low impedance, high ripple-current capability and extended endurance in a compact φ12.5 × 30.5 mm package.

Key value propositions include high ripple-current handling (2.632 A at 120 Hz / 3.29 A at 100 kHz), a wide operating temperature range of −40 °C to +105 °C, and a 5000-hour endurance rating at 105 °C, making it suitable for demanding power-filtering and bulk-energy-storage roles in production designs.

Key Features

• Capacitance & Voltage — 1800 µF nominal capacitance at a rated voltage of 25 V with ±20% tolerance for general-purpose power applications.
• Low Impedance / Loss — Specified tangent of loss angle (tanδ) of 0.14 at 20 °C and 120 Hz to support stable performance under AC ripple conditions.
• High Ripple Current — Low-frequency ripple current of 2.632 A (120 Hz) and high-frequency ripple current of 3.29 A (100 kHz) to handle substantial AC stress in power circuits.
• Endurance & Reliability — 5000-hour rated lifetime at 105 °C with defined limits for capacitance change, tanδ, and leakage current after endurance testing.
• Wide Temperature Range — Operates from −40 °C to +105 °C to accommodate a broad range of ambient conditions.
• Radial Can Package — φ12.5 × 30.5 mm aluminum can with 5 mm lead spacing (±0.5 mm) and radial-lead mounting for through-hole PCB assemblies; available in bulk/bag packing.
• Leakage Current — Low leakage current specified at 450 µA (product data) and datasheet guidance for leakage measurement after rated voltage application.
• RoHS Compliant & Production Ready — RoHS compliant and listed as mass production status for reliable supply and manufacturing integration.

Typical Applications

• General-Purpose Power Filtering — Bulk smoothing and decoupling in power supplies and DC rails where 1800 µF capacitance and 25 V rating are required.
• Industrial Electronics — Energy buffering and ripple suppression in industrial control and instrumentation operating across −40 °C to +105 °C.
• Power Conversion Subsystems — Support for AC ripple and transient currents in converters, inverters, and DC/DC stages that demand high ripple-current capability.

Unique Advantages

• High ripple-current capability: 2.632 A (120 Hz) and 3.29 A (100 kHz) ratings reduce thermal stress and extend service life in ripple-heavy circuits.
• Extended endurance: 5000 hours at 105 °C provides predictable long-term performance for production designs.
• Compact radial can: φ12.5 × 30.5 mm package with 5 mm lead spacing saves board space while enabling robust through-hole mounting.
• Wide operating range: −40 °C to +105 °C operation supports deployment across varied environmental conditions.
• Verified low loss: tanδ of 0.14 at 20 °C / 120 Hz offers reduced AC dissipation for improved efficiency under ripple.
• Production-ready supply: RoHS compliance and mass-production status simplify procurement and qualification for volume builds.
