UPA1E182MHD

The UPA1E182MHD is a radial-lead aluminum electrolytic capacitor designed for general-purpose power applications. As part of the UPA series, it delivers a miniature, low-impedance construction optimized for switching power supplies and power-rail smoothing where high ripple handling and long-term reliability are required.

Key value comes from its high capacitance (1,800 µF) at a 25 V rating, low impedance and elevated ripple-current capability, combined with a wide operating temperature range and long endurance at elevated temperature.

Key Features

• Capacitance & Tolerance — 1,800 µF with tolerance −20% to +20% at 120 Hz, 20 °C, suitable for bulk energy storage and smoothing.
• Rated Voltage — 25 V DC rating for common power-rail applications.
• Low Impedance — Impedance of 44 mΩ, supporting lower voltage ripple and improved transient response in power circuits.
• High Ripple Current — Rated low-frequency ripple current 1.938 A (120 Hz) and high-frequency ripple current 2.28 A (100 kHz), enabling reliable operation under substantial AC ripple conditions.
• Loss Tangent (tan δ) — tan δ = 0.14 measured at 20 °C, 120 Hz, indicating controlled dissipation for the rated voltage.
• Leakage Current — Specified leakage current of 1,350 µA after rated voltage application.
• Endurance & Reliability — Rated for 5,000 hours at 105 °C under DC bias plus rated ripple current (φ12.5 case endurance specification).
• Operating Temperature Range — −55 °C to +105 °C for wide environmental tolerance.
• Compact Radial Package — φ12.5 × 25L can with radial leads, 5 mm lead spacing (±0.5 mm), available in bulk or bag packing for board-level assembly.
• RoHS Compliant — Meets RoHS requirements for regulated material content.

Typical Applications

• Switching Power Supplies — Bulk smoothing and decoupling in converters where low impedance and high ripple current extend service life and improve regulation.
• Power-Rail Filtering — Energy storage and transient suppression on DC rails in general-purpose electronic equipment.
• Industrial and Consumer Power Modules — General-purpose bulk capacitance for power management tasks across a range of non-automotive devices.

Unique Advantages

• High Ripple-Handling Capability: Rated ripple currents of 1.938 A (120 Hz) and 2.28 A (100 kHz) reduce heating and improve longevity under AC stress.
• Low-Impedance Performance: 44 mΩ impedance supports tighter voltage regulation and lower ripple on power rails.
• Extended Endurance at Elevated Temperature: 5,000-hour rating at 105 °C provides predictable aging for designs expected to operate in hot environments.
• Wide Temperature Range: −55 °C to +105 °C enables use across varied ambient conditions.
• Space-Efficient Radial Can: φ12.5 × 25L packaging with 5 mm lead spacing offers a compact solution for through-hole assemblies.
• Regulatory Compliance: RoHS-compliant construction supports environmental and supply-chain requirements.
