UPM1V331MHD6

The UPM1V331MHD6 is a miniature, high-reliability radial lead aluminum electrolytic capacitor in Nichicon’s UPM series. It provides 330 µF capacitance at a 35 V rating in a compact φ12.5 × 15 mm can with 5 mm lead spacing, designed for demanding power-filtering and decoupling tasks.

Engineered for long-term operation, the device offers low impedance (65 mΩ), defined ripple-current capability, and a guaranteed endurance of 5000 hours at 105°C, making it suitable for applications requiring robust thermal and electrical stability.

Key Features

• Rated Capacitance and Voltage — 330 µF capacitance with a 35 V rated voltage and ±20% tolerance, suitable for bulk filtering and energy storage on DC rails.
• Low Impedance — 65 mΩ impedance that supports effective ripple suppression and improved transient response in power circuits.
• Ripple Current Handling — Designed for 452.4 mA at 120 Hz (low frequency) and 780 mA at 200 kHz (high frequency), enabling reliable operation under AC ripple loads.
• High Reliability Endurance — 5000 hours life at 105°C under rated conditions, specified for long-term performance and stability.
• Wide Temperature Range — Operates from −55°C to +105°C to cover wide ambient conditions.
• Electrical Losses — tanδ (DF) 0.12 measured at 20°C, 120 Hz, providing predictable dissipation characteristics for design calculations.
• Compact Radial Package — Radial lead can with φ12.5 mm diameter, 15 mm length, and 5 mm lead spacing for through-hole PCB designs; available in bulk/bag packing.
• Compliance and Qualification — RoHS compliant and AEC-Q200 rated, supporting regulated and automotive-oriented applications.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling on DC power rails where 330 µF at 35 V is required for stable voltage delivery.
• DC-DC Converters — Input/output filtering and energy buffering in converter stages, leveraging the part’s low impedance and defined ripple-current specs.
• Automotive Electronics — Suitable for control modules and subsystems that require AEC-Q200-qualified components and long endurance at elevated temperatures.
• Industrial Control — Power conditioning and transient suppression in industrial equipment operating across −55°C to +105°C.

Unique Advantages

• Long Endurance at Elevated Temperature — 5000 hours at 105°C ensures predictable lifetime behavior in high-temperature environments.
• Measured High-Frequency Performance — Specified 780 mA ripple at 200 kHz supports switching regulator and high-frequency converter designs.
• Compact Footprint for Through-Hole Designs — φ12.5 × 15 mm can and 5 mm lead spacing provide a small-capacity, high-performance option for dense PCB layouts.
• Low Leakage and Predictable Losses — Defined leakage current (346.5 µA) and tanδ (0.12 at 120 Hz, 20°C) allow accurate power-loss and standby-current budgeting.
• Automotive-Grade Qualification — AEC-Q200 rating and RoHS compliance support use in regulated and automotive applications where qualified components are required.
