UHD1E152MHD

The UHD1E152MHD is a 1500 µF, 25 V polarized aluminum electrolytic capacitor in a radial lead can (φ12.5 × 25 mm) designed for general-purpose electronic applications. It combines high ripple-current capability and reduced high-frequency impedance with a compact footprint and long endurance for sustained operation at elevated temperatures.

Key Features

• Capacitance & Voltage – 1500 µF nominal capacitance rated at 25 V with a tolerance of −20% to +20%.
• High ripple-current capability – Rated for 2.216 A at 120 Hz (low frequency) and 2.77 A at 100 kHz (high frequency), supporting demanding ripple loads.
• Low high-frequency impedance – UHD series specification highlights lower impedance at high frequencies, helping maintain performance under switching or high-frequency ripple conditions.
• Dissipation factor (tan δ) – tan δ = 0.14 measured at 20°C, 120 Hz, providing a quantified loss metric for AC performance.
• Leakage current – Specified leakage current of 375 µA, measured under standard conditions.
• Endurance at elevated temperature – 5000 hours rated life at 105°C under applied DC bias plus rated ripple current, with defined limits for capacitance change, tan δ, and leakage current.
• Operating temperature range – −40°C to +105°C to accommodate a wide range of ambient conditions.
• Compact radial package – φ12.5 × 25 mm can, radial lead mounting with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• RoHS compliant – Meets RoHS directive requirements as stated for the UHD series.

Typical Applications

• General-purpose electronic designs – Suited for circuits that require a 1500 µF, 25 V polarized radial electrolytic with reliable performance over temperature.
• High-ripple environments – Appropriate where higher ripple currents and lower impedance at higher frequencies are necessary, as indicated by the specified ripple-current ratings.
• Elevated-temperature operation – Designed for use in applications that demand continuous operation up to 105°C with a 5000-hour endurance rating.

Unique Advantages

• Proven ripple handling: Explicit ripple-current ratings of 2.216 A (120 Hz) and 2.77 A (100 kHz) give designers clear margins for AC-stressed circuits.
• Defined high-temperature lifetime: 5000 hours at 105°C provides predictable endurance characteristics for thermal reliability planning.
• Measured dissipation factor: tan δ = 0.14 (20°C, 120 Hz) supplies a quantified loss parameter for AC design considerations.
• Compact, serviceable form factor: φ12.5 × 25 mm radial can with 5 mm lead spacing offers a small footprint with through-hole mounting ease.
• Clear leakage specification: Leakage current specified at 375 µA enables straightforward leakage budgeting in power-sensitive designs.
• Standards-compliant materials: RoHS compliance aligns the component with common environmental requirements.

Why Choose UHD1E152MHD?

The UHD1E152MHD positions itself as a reliable, general-purpose radial aluminum electrolytic capacitor that combines significant capacitance (1500 µF) at 25 V with explicit high-ripple capability and a long, defined life at elevated temperature (5000 h at 105°C). Its measured parameters—tan δ, leakage current, and ripple ratings—provide engineers with concrete data for thermal, AC-loss, and reliability tradeoffs.

This part is well suited to designs that require a compact, polarized electrolytic with clear performance characteristics under ripple stress and elevated temperature. The combination of low high-frequency impedance (UHD series trait), quantified loss and leakage figures, and RoHS compliance supports predictable integration into general-purpose electronic assemblies.
