UPW1E330MDD

The UPW1E330MDD is a radial‑lead aluminum electrolytic capacitor from Nichicon’s UPW series designed for miniature, low‑impedance power filtering in switching power supplies. It delivers 33 µF at 25 V in a compact radial can package engineered for robust operation across a wide temperature range.

Targeted for automotive and other demanding applications, the part combines AEC‑Q200 qualification with a –55 °C to +105 °C operating range and a specified lifetime of 2000 hours at 105 °C, making it suitable where reliability and thermal endurance are required.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a rated voltage of 25 V and ±20% tolerance to support decoupling and bulk smoothing in power rails.
• Low Impedance / Ripple Handling — Rated ripple current of 54 mA at 120 Hz and 180 mA at 10 kHz provides improved AC performance for switching converters and high‑frequency ripple suppression.
• Compact Radial Can Package — Small footprint with dimensions L: 1.1 cm × D: 0.5 cm and 2 mm lead spacing, enabling tight board layouts and dense power assemblies.
• Automotive Reliability — AEC‑Q200 rating indicates design and manufacturing controls aligned with automotive component requirements.
• Wide Temperature Range & Lifetime — Operating temperature from –55 °C to +105 °C and a guaranteed lifetime of 2000 hours at 105 °C for sustained performance under elevated temperatures.
• Polarized Radial Lead Mounting — Standard polarized aluminum electrolytic construction with radial lead configuration for through‑hole mounting and straightforward assembly.

Typical Applications

• Automotive Electronics — Energy smoothing and decoupling in automotive power modules and electronics where AEC‑Q200 qualification and elevated temperature endurance are required.
• Switching Power Supplies — Input/output filtering and ripple suppression in compact DC‑DC converters and switching regulators.
• Power Management Modules — Bulk and local decoupling in compact power distribution boards that demand small size and reliable high‑temperature performance.

Unique Advantages

• Compact footprint: Small L × D (1.1 cm × 0.5 cm) enables high-density board layouts and space‑constrained designs.
• Frequency capability for real-world ripple: Specified ripple currents at 120 Hz and 10 kHz demonstrate usable AC performance across both low and high switching frequencies.
• Automotive‑grade qualification: AEC‑Q200 rating supports use in designs that require automotive component level controls.
• Extended thermal range and proven lifetime: –55 °C to +105 °C operation and 2000 hours at 105 °C help ensure stable performance in elevated temperature environments.
• Through‑hole robustness: Radial lead, polarized can construction provides mechanical durability and straightforward soldering for power assemblies.
