UVY2C331MHD

The UVY2C331MHD is a radial-leaded aluminum electrolytic capacitor from Nichicon's UVY series, offering 330 µF capacitance at a 160 V rating. Built for general-purpose power filtering and energy storage, it combines high-voltage capability with a compact radial can package and through-hole leads for reliable PCB mounting.

Key value propositions include a wide operating temperature range down to −40°C, a 2000-hour endurance rating at 105°C, RoHS compliance, and measurable ripple current performance specified for both low and high frequency operation.

Key Features

• Capacitance & Voltage — 330 µF capacitance rated at 160 V, suitable for bulk decoupling and smoothing in medium-voltage DC circuits.
• Ripple Handling — Rated ripple current of 570 mA at 120 Hz and 655.5 mA at 10 kHz, enabling both low-frequency and higher-frequency ripple dissipation as specified for the part.
• Leakage Current — Specified leakage current of 2212 µA, providing a defined standby loss characteristic for power designs.
• Thermal & Endurance — Operating temperature range −40°C to +105°C with an endurance specification of 2000 hours at 105°C, supporting sustained operation in elevated-temperature environments.
• Package & Mounting — Radial lead, can-style package with φ18 × 35.5 mm body dimensions and 7.5 mm lead spacing for through-hole assemblies and robust mechanical retention.
• Compliance & Production — RoHS compliant and available in bulk/bag packing for mass production requirements.

Typical Applications

• Power Supply Filtering — Bulk smoothing and output filtering in medium-voltage DC power supplies where 160 V rating and 330 µF capacitance are required.
• DC Link / Energy Storage — Local energy reservoir for converters and regulators that require reliable ripple handling and defined leakage characteristics.
• Industrial Electronics — General-purpose filtering and decoupling in industrial control equipment operating across a wide temperature range up to 105°C.
• Instrumentation & Test Equipment — Stabilization and noise reduction in measurement and control circuits that demand predictable endurance and ripple performance.

Unique Advantages

• High-voltage capability: 160 V rated voltage enables use in higher DC bus and intermediate-voltage circuits without stacking multiple components.
• Defined ripple specs at two frequencies: Published ripple current values at 120 Hz and 10 kHz make it easier to assess thermal and lifetime impact across typical switching and line-frequency environments.
• Robust thermal endurance: 2000 hours at 105°C provides predictable lifetime performance for elevated-temperature applications.
• Through-hole reliability: Radial lead can with 7.5 mm lead spacing offers secure PCB mounting and straightforward assembly for repairable or mechanically demanding designs.
• RoHS compliant and production-ready: Conforms to RoHS and is supplied in bulk/bag packing, supporting volume manufacturing and procurement workflows.
• Series advantages: Part of the UVY series, which is documented to offer a wide temperature range and compact case sizing within the series family.
