UPW1H330MED

The UPW1H330MED is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPW series, designed for low-impedance performance in switching power supplies. It is a polarized radial-lead can rated at 50 V with 330 µF nominal capacitance and a wide operating temperature range of −55 °C to 105 °C.

This part is specified for demanding power-filtering roles where compact size, controlled dissipation factor, and defined ripple handling are required. It is AEC‑Q200 rated and targeted toward applications that need proven endurance and stable electrical behavior across temperature and frequency.

Key Features

• Capacitance & Tolerance — 330 µF nominal capacitance with tolerance of -20% to +20% for predictable energy storage in DC filtering and bulk decoupling.
• Rated Voltage — 50 V working voltage suitable for a range of mid-voltage power rails.
• Low Dissipation Factor — tan δ = 0.10 (measured at 20 °C, 120 Hz), supporting lower losses in AC ripple environments.
• Ripple Current Capability — Low-frequency ripple current 90 mA (120 Hz) and high-frequency ripple current 300 mA (10 kHz) for handling both mains-frequency and switching-frequency ripple components.
• Leakage Current — Specified leakage current of 49.5 µA for predictable bias losses after application of rated voltage.
• High-Temperature Endurance — Rated life of 2000 hours at 105 °C, enabling sustained operation in elevated-temperature environments.
• Compact Radial Package — Small can size φ6.3 × 11 mm length with 2.5 mm lead spacing (±0.5 mm), ideal for space-constrained through-hole layouts.
• Mounting & Packaging Options — Radial lead mounting; supplied in bulk (no terminal forming) or bag packing to support assembly processes.
• AEC‑Q200 Qualification — AEC‑Q200 rating for component-level reliability requirements in regulated environments.

Typical Applications

• Switching Power Supplies — Low impedance and specified ripple handling make this capacitor suited for output and bulk filtering in compact switch-mode power converters.
• Automotive Electronics — AEC‑Q200 qualification and 105 °C endurance support use in automotive electronic modules requiring reliable DC filtering.
• Space-Constrained Power Circuits — The φ6.3 × 11 mm radial can and tight lead spacing enable deployment where board area is limited but reliable capacitance is required.

Unique Advantages

• Designed for switching environments — Low tan δ and defined ripple-current ratings across frequency bands help control losses and thermal rise in switching circuitry.
• Temperature and endurance specification — Rated for −55 °C to 105 °C operation with 2000 hours endurance at 105 °C to support sustained performance under elevated temperatures.
• Compact through-hole form factor — Small radial can with 2.5 mm lead spacing facilitates dense PCB layouts without sacrificing capacitance.
• AEC‑Q200 reliability — Qualification aligned with component-level reliability programs, aiding designs that require traceable quality standards.
• Practical packaging choices — Bulk (no terminal forming) and bag packing options accommodate different assembly workflows and handling preferences.
• Predictable leakage and loss characteristics — Specified leakage current and dissipation factor values enable predictable bias and thermal budgeting in system design.
