UPS2E3R3MPD

The UPS2E3R3MPD is a miniature, low-impedance aluminum electrolytic capacitor in a radial lead can designed for switching power supplies and general-purpose power filtering. It delivers 3.3 µF capacitance at a 250 V rating in a compact radial package suitable for space-constrained through-hole designs.

Key value drivers include a wide operating temperature range, low impedance characteristics for ripple suppression, and RoHS compliance—making it appropriate for power modules and compact supply circuits that require reliable high-voltage smoothing.

Key Features

• Electrical — 3.3 µF, 250 V Precise 3.3 µF capacitance with a 250 V rated voltage for high-voltage smoothing and energy storage in power circuits.
• Low Impedance & Ripple Handling Specified ripple current of 42 mA at 120 Hz and 67.2 mA at 10 kHz supports effective filtering of switching noise in power supplies.
• Wide Temperature Range Operational from −40 °C to 105 °C to support a broad range of ambient conditions encountered in commercial power electronics.
• Durability / Lifetime Rated lifetime of 2000 hours at 105 °C, with series endurance specifications indicating capacitance and leakage stability after rated stress.
• Radial Lead Package Through-hole radial lead (can) construction with 5 mm lead spacing and compact dimensions (L: 12.5 mm × D: 10 mm) for straightforward PCB mounting and mechanical stability.
• RoHS Compliant Manufactured to meet RoHS directive requirements (2011/65/EU,(EU)2015/863) for lead-free assemblies.
• Polarized Design Polarized electrolytic construction for DC filtering and bulk energy storage in power supply topologies.

Typical Applications

• Switching Power Supplies Local smoothing and ripple suppression on high-voltage rails in isolated and non-isolated switch-mode power supplies.
• DC–DC Converters Input or output decoupling where a compact, high-voltage capacitor is required for transient and ripple control.
• Power Management Modules Bulk and bypass capacitance in compact power modules and power-conditioning circuits.
• General-Purpose Electronics Through-hole designs requiring a reliable, miniature electrolytic for filtering and energy storage at elevated voltages.

Unique Advantages

• Compact footprint: Small can dimensions (L: 12.5 mm × D: 10 mm) and 5 mm lead spacing save PCB area in constrained designs.
• High-voltage capability: 250 V rating enables use on higher-voltage rails without stacking multiple components.
• Low-impedance performance: Specified ripple current values at both low and high frequencies help reduce output ripple and improve regulator stability.
• Extended operating range: −40 °C to 105 °C operation makes the part suitable for varied commercial environments.
• Proven endurance characteristics: Series endurance data provide predictable capacitance retention and leakage behavior after rated-life stress.
• Regulatory compliance: RoHS compliance supports lead-free assembly requirements.
