UPS1E102MHD

The UPS1E102MHD is a miniature, low‑impedance aluminum electrolytic capacitor designed for switching power supplies and general-purpose electronic circuits. It is a polarized, radial‑lead can that delivers 1 mF capacitance at a 25 V rating with a compact footprint (L: 2 × D: 1.25 cm).

Engineered for wide temperature operation and sustained performance under load, this capacitor supports an operating range of –55 °C to +105 °C and a specified endurance of 3000 hours at 105 °C, offering designers predictable behavior in demanding power environments.

Key Features

• Capacitance & Voltage — 1 mF (1000 μF) nominal capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low Impedance — Specified impedance of 75 mΩ to help reduce ripple and improve power‑rail stability in switching regulators.
• Ripple Current Capability — Rated ripple current of 1.087 A at 120 Hz and 1.25 A at 10 kHz to support AC stress from converters and switching supplies.
• Wide Temperature Range — Operating temperature from –55 °C to +105 °C for extended environmental tolerance.
• Endurance at Elevated Temperature — 3000 hours life at 105 °C under rated voltage and ripple current, with defined limits for capacitance change, tan δ, and leakage current.
• Radial Can, Through‑Hole Mounting — Radial lead mounting and can package for easy placement in through‑hole assemblies; lead spacing is 5 mm.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and defined ripple current handling improve regulator stability and transient response.
• General‑Purpose Power Filtering — Smoothing and decoupling in a wide range of electronic circuits that require a polarized electrolytic capacitor with compact size.
• Through‑Hole Power Modules — Integration into radial‑lead assemblies and PCB layouts that prefer can‑type capacitors for serviceability and mechanical robustness.

Unique Advantages

• Measured Low‑Ohmic Performance — 75 mΩ impedance provides tangible reduction in AC voltage drop across the capacitor under ripple conditions.
• Designed for High Ripple Environments — Rated ripple currents at both low and high frequencies (1.087 A at 120 Hz; 1.25 A at 10 kHz) support switching applications across typical power converter bandwidths.
• Wide Thermal Range with Proven Endurance — –55 °C to +105 °C operation and a 3000‑hour endurance at 105 °C help maintain capacitance and leakage specifications over prolonged high‑temperature use.
• Compact Radial Package — Small can footprint (L: 2 × D: 1.25 cm) and 5 mm lead spacing enable dense PCB layouts while retaining through‑hole mechanical stability.
• Regulatory Compliance — RoHS compliant for use in designs targeting restricted‑substance conformity.
