UPS2F3R3MPD

The UPS2F3R3MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPS series. It is a polarized radial-lead, can-type capacitor designed for switching power supplies and general-purpose power filtering applications.

Built for compact power designs, the UPS2F3R3MPD combines a 3.3 µF capacitance with a 315 V rating, specified ripple current performance, and a wide operating temperature range to support demanding board-level power tasks.

Key Features

• Capacitance & Tolerance: 3.3 µF nominal with a tolerance of −20% to +20%, suitable for precision decoupling and energy-storage tasks where known tolerance bounds are required.
• High Voltage Rating: Rated at 315 V, providing high-voltage handling for power-supply rails and high-side filtering applications.
• Low-loss Characteristic: Tangent of loss angle (tanδ) of 0.2 measured at 20°C, 120 Hz, reflecting the component’s AC loss behavior under typical measurement conditions.
• Ripple Current Performance: Low-frequency ripple current of 34 mA at 120 Hz and high-frequency ripple current of 54.4 mA at 10 kHz, supporting switching supply ripple handling across frequencies.
• Leakage Current: Specified leakage current of 141.58 µA, measured after application of rated voltage, for predictable standby power behavior.
• Temperature & Endurance: Operating range −40°C to 105°C with a rated life of 2000 hours at 105°C, providing defined performance under elevated temperature stress.
• Form Factor & Mounting: Radial lead, polarized can package with case dimension φ10 × 12.5 mm and 5 mm lead spacing (±0.5 mm), enabling compact through-hole integration.
• Packaging & Compliance: Available in bulk (no terminal forming) and bag packing; RoHS compliant.
• Product Status: End Of Life (EOL) status for planning and procurement considerations.

Typical Applications

• Switching Power Supplies: Used for output filtering and ripple suppression in switching regulators where compact, high-voltage capacitance is required.
• General-Purpose Power Filtering: Board-level smoothing and decoupling for high-voltage rails in industrial or consumer power electronics.
• Space-Constrained Designs: Miniature φ10 × 12.5 mm can and radial-lead footprint suit compact or densely populated PCBs needing through-hole capacitors.

Unique Advantages

• High-voltage capability: 315 V rating addresses higher-voltage rails without the need for series stacking of lower-voltage parts.
• Compact footprint: φ10 × 12.5 mm case and 5 mm lead spacing minimize board area while delivering useful capacitance for power circuits.
• Designed for switching supplies: Series designation and specified ripple current values indicate suitability for switching-regulator ripple handling and filtering.
• Defined thermal endurance: 2000-hour life at 105°C provides a measurable reliability baseline for thermal-stressed designs.
• Predictable leakage and loss: Specified leakage current and tanδ give clear electrical expectations for standby loss and AC dissipation.
• RoHS compliant: Conforms to RoHS requirements for environmental and regulatory compatibility.
