UPS2C331MRD

The UPS2C331MRD is a miniature, low-impedance aluminum electrolytic capacitor in a radial-lead can designed for switching power supplies and general-purpose power applications. It delivers 330 µF capacitance at a 160 V rating with polarized radial leads and a compact footprint for through-hole assemblies.

Engineered for a wide operating temperature range and extended life at elevated temperature, this part supports designs that require stable bulk capacitance, ripple handling, and RoHS-compliant materials.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a 160 V rated voltage and tolerance of ±20%, providing bulk energy storage for high-voltage DC circuits.
• Low Impedance Design: Described as low impedance, optimized for switching power supplies where reduced ESR helps improve regulation and ripple attenuation.
• Ripple Current Capability: Specified ripple current of 900 mA at 120 Hz and 1.035 A at 10 kHz, enabling effective handling of AC ripple across common switching frequencies.
• Temperature & Lifetime: Operating temperature range of −40°C to +105°C with a lifetime rating of 3000 hours at 105°C under rated conditions, suitable for sustained elevated-temperature operation.
• Package & Mounting: Radial leaded can with 10 mm (1 cm) lead spacing and compact dimensions (L: 4 × D: 2 cm), simplifying through-hole placement in tight boards.
• Compliance: RoHS compliant (2011/65/EU, (EU)2015/863), meeting common materials-restriction requirements.

Typical Applications

• Switching Power Supplies: Bulk capacitance and low-impedance construction support output filtering and energy storage in switch-mode power supplies.
• Power Filtering and Decoupling: Used where stable capacitance and ripple handling are needed to smooth DC rails and reduce noise.
• General-Purpose Electronics and Industrial Equipment: Suitable for board-level through-hole implementations requiring a robust, polarized high-voltage electrolytic capacitor across −40°C to +105°C.

Unique Advantages

• High Voltage Capability: 160 V rating enables use in higher-voltage DC circuits without series stacking.
• Compact, Miniature Footprint: Small radial-can dimensions (L: 4 × D: 2 cm) and 10 mm lead spacing allow dense through-hole layouts.
• Measured Ripple Ratings: Published ripple current values at both low and high frequencies (900 mA @120 Hz, 1.035 A @10 kHz) give designers quantifiable limits for thermal and lifetime calculations.
• Wide Operating Range: −40°C to +105°C operation enables use across many ambient environments and thermal conditions.
• Long Elevated-Temperature Life: 3000 hours at 105°C provides a defined endurance metric for high-temperature applications and reliability planning.
• RoHS Compliant: Conforms to current RoHS directives for restricted substances, simplifying regulatory compliance.
