UPW2E330MHD

The UPW2E330MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPW series, designed for compact power applications that demand low impedance and reliable long-term operation. This polarized can-type capacitor delivers 330 µF at a 250 V rating, with a miniature φ12.5 × 25 mm package and 5 mm lead spacing for through-hole mounting.

Key performance highlights include a wide operating range from −40 °C to 105 °C and a rated endurance of 7000 hours at 105 °C. Status: End Of Life.

Key Features

• Rated Capacitance & Voltage — 330 µF nominal capacitance at a 250 V rated voltage, suitable for energy storage and smoothing in power circuits.
• Low Loss Factor — tan δ (dissipation factor) of 0.15 measured at 20 °C, 120 Hz, supporting efficient AC performance in filtering and decoupling tasks.
• Ripple Current Capability — Low-frequency ripple current 190 mA (120 Hz) and high-frequency ripple current 304 mA (10 kHz), enabling effective handling of both line-frequency and switching noise.
• Leakage Current — Specified leakage current of 430 µA, providing predictable standby current behavior for power designs.
• High Temperature Endurance — Rated life of 7000 hours at 105 °C, supporting long-term reliability under elevated operating temperatures.
• Compact Radial Can Package — φ12.5 mm diameter × 25 mm length (L), radial lead mounting with 5 mm lead spacing (±0.5 mm), packaged in bulk or bag for manufacturing flexibility.
• Polarized Construction — Conventional polarized aluminum electrolytic suited for DC bulk storage and power supply smoothing.
• AEC-Q200 Rating — AEC-Q200 listed in the product data, indicating suitability for designs that reference that industry qualification.

Typical Applications

• Automotive power systems — Bulk energy storage and smoothing in vehicle power electronics where AEC-Q200-level components are used.
• Switching power supplies — Output filtering and ripple reduction for compact SMPS designs, leveraging the capacitor’s low impedance and specified ripple currents.
• Industrial power electronics — DC link and smoothing roles in industrial converters and control modules requiring high-temperature endurance.

Unique Advantages

• High voltage capacity in a small footprint: 250 V rating in a φ12.5 × 25 mm can enables conservative voltage margin without large board area.
• Designed for sustained high-temperature operation: 7000-hour endurance at 105 °C offers predictable lifetime for thermally demanding designs.
• Dual-frequency ripple handling: Specified ripple currents at both low (120 Hz) and high (10 kHz) frequencies make it versatile for mixed-frequency noise environments.
• Predictable leakage and loss characteristics: Specified leakage current (430 µA) and tan δ (0.15 at 20 °C, 120 Hz) help with power budgeting and thermal planning.
• Through-hole radial packaging: 5 mm lead spacing and standard radial can construction simplify prototyping, hand-assembly, and repairable designs.
