Key Features

• Capacitance & Voltage — 3.3 µF nominal capacitance with a 315 V rated voltage and tolerance of −20% to +20%.
• Low Loss — Specified tan δ = 0.2 measured at 20°C, 120 Hz for low dissipation in filtering applications.
• Ripple Current Performance — Low‑frequency ripple current 34 mA at 120 Hz and high‑frequency ripple current 54.4 mA at 10 kHz to support switching power environments.
• Leakage Current — Leakage current specified at 141.58 µA, supporting predictable bias behavior after application of rated voltage.
• High‑Temperature Endurance — Life/endurance rating of 5000 hours at 105°C for sustained elevated‑temperature use.
• Compact Radial‑Lead Package — Can package with radial leads, diameter φ10 mm and length 12.5 mm (L: 1.25 cm × D: 1.0 cm), and 5 mm lead spacing (±0.5 mm).
• Polarized Construction — Polar capacitor type suitable for DC power applications.
• AEC‑Q200 Rated — Built to an AEC‑level reliability rating suitable for automotive electronics and other high‑reliability applications.

Typical Applications

• Switching Power Supplies — Low impedance and defined ripple current capability make the UPW2F3R3MPD suitable for output filtering and smoothing in compact switch‑mode converters.
• Automotive Power Systems — AEC‑Q200 rating and 5000 h endurance at 105°C support use in automotive electronic modules that require high thermal reliability.
• Compact Power Modules — Small φ10 × 12.5 mm can and radial lead format enable use where board area and height are constrained.
• General Power Filtering — Polarized aluminum electrolytic for DC bus decoupling and bulk smoothing in industrial and embedded power designs.

Unique Advantages

• High Voltage Capability: 315 V rating allows use in higher‑voltage DC rails without resorting to larger packages.
• Thermal Endurance: 5000 hours at 105°C provides measurable lifetime performance for elevated‑temperature applications.
• Compact Footprint: φ10 mm × 12.5 mm can with 5 mm lead spacing delivers a small‑form solution for space‑limited assemblies.
• Defined Frequency Performance: Measured tan δ = 0.2 at 20°C, 120 Hz and specified ripple current values clarify expected behavior across frequency ranges.
• Automotive‑Grade Reliability: AEC‑Q200 rating aligns the part to high‑reliability requirements found in automotive electronics.
