UPS2E101MHD

The UPS2E101MHD is a miniature, low-impedance aluminum electrolytic capacitor in a radial lead can, designed for power-supply filtering and general-purpose DC smoothing. It delivers 100 µF at 250 V with a compact φ18 × 35.5 mm case and 7.5 mm lead spacing for through-hole mounting.

Engineered for elevated-temperature operation, the capacitor is rated for use from -40°C to 105°C with an endurance of 3000 hours at 105°C. Note: Status — End Of Life.

Key Features

• Electrical Performance — 100 µF capacitance with ±20% tolerance and a rated voltage of 250 V, suitable for medium-voltage DC filtering and energy storage.
• Low Loss Characteristic — Dissipation factor (tan δ) of 0.15 measured at 20°C, 120 Hz, for predictable impedance and loss in power circuits.
• Ripple Current Capability — Rated ripple current of 340 mA at 120 Hz and 544 mA at 10 kHz to support AC ripple handling in switching supplies.
• Reliability & Lifetime — Endurance specification of 3000 hours at 105°C under rated DC bias and ripple conditions, with leakage current specified at 1100 µA.
• Mechanical & Packaging — Radial lead, can-style package with φ18 × 35.5 mm dimensions and 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low-impedance, miniature form factor for output smoothing and bulk decoupling in switch-mode supplies.
• General Purpose Power Filtering — Provides DC smoothing and ripple reduction in general-purpose power circuits requiring 250 V rating and elevated-temperature endurance.
• Space-Constrained Power Modules — Compact φ18 × 35.5 mm can and radial leads simplify integration into through-hole power assemblies with limited board area.

Unique Advantages

• High Voltage Capability: 250 V rated voltage enables use where higher DC rail handling is required.
• Compact, Low-Impedance Design: Miniature can size with a low loss tangent supports tight layouts without sacrificing ripple performance.
• Measured Ripple Ratings: Specified ripple current at 120 Hz and 10 kHz (340 mA / 544 mA) provides clear guidance for thermal and lifetime planning.
• Proven Endurance: 3000 hours at 105°C under rated conditions gives a defined reliability envelope for high-temperature applications.
• Through-Hole Mounting: Radial lead package and 7.5 mm lead spacing simplify assembly and replacement in legacy and industrial boards.
• RoHS Compliant: Conforms to applicable environmental restrictions for regulated markets.
