UHE1E122MHD

The UHE1E122MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can intended for general-purpose electronic use. It delivers 1200 µF at 25 V with engineered low impedance, elevated ripple-current capability, and a long rated life for sustained operation at elevated temperature.

Designed for applications that require bulk capacitance in a compact footprint, the UHE1E122MHD combines a φ18 × 15 mm can, 7.5 mm lead spacing and polarization suited to through-hole implementations where endurance and ripple handling matter.

Key Features

• Capacitance & Voltage: 1200 µF nominal capacitance at a rated voltage of 25 V, with tolerance of −20% to +20% for general-purpose design margin.
• Low Impedance: Specified impedance of 110 mΩ helps reduce voltage ripple and impedance-related losses in power circuits.
• High Ripple Current Handling: Low-frequency ripple current 1.768 A (120 Hz) and high-frequency ripple current 2.21 A (10 kHz) to support both mains-frequency and high-frequency switching environments.
• Long Endurance: Life rating of 10000 h at 105 °C that supports extended service life under elevated-temperature stress.
• Temperature Range: Rated for operation from −40 °C to +105 °C, enabling use across a wide thermal envelope.
• Leakage & Loss: Leakage current specified at 300 µA and tangent of loss angle (tan δ) listed as 0.14 (measured at 20 °C, 120 Hz), providing predictable electrical behavior.
• Package & Mounting: Radial-lead can (φ18 × 15 mm) with 7.5 mm lead spacing and lead spacing tolerance ±0.5 mm for reliable through-hole mounting. Available in bulk (no terminal forming) or bag packing.
• Regulatory Status: RoHS compliant and in mass production for supply continuity.

Typical Applications

• General-purpose electronics: Bulk energy storage and smoothing where 1200 µF at 25 V and low impedance improve voltage stability.
• Power circuitry in embedded devices: Filtering and ripple attenuation where high ripple-current capability and a −40 °C to +105 °C temperature range are required.
• Industrial and consumer equipment: Long-life endurance (10000 h at 105 °C) supports sustained operation in equipment with extended duty cycles.

Unique Advantages

• High ripple tolerance: Specified ripple currents at both low and high frequency reduce thermal stress and extend capacitor lifetime in switching environments.
• Compact, serviceable package: φ18 × 15 mm radial can with 7.5 mm lead spacing provides a small footprint for through-hole assemblies while maintaining serviceability.
• Predictable loss and leakage: Defined tan δ and leakage current figures support reliable circuit modeling and predictable power loss estimates.
• Extended high-temperature life: 10000-hour rating at 105 °C enables designs that must maintain capacitance and performance over prolonged elevated-temperature exposure.
• RoHS compliance and mass-production availability: Ensures regulatory conformity and steady supply for production programs.
