UHV0J331MED

The UHV0J331MED is a radial-lead aluminum electrolytic capacitor from Nichicon's UHV series. It delivers 330 µF capacitance at a rated voltage of 6.3 V in a compact φ6.3 × 11 mm can, targeting general-purpose electronic applications that require low impedance and robust ripple handling.

Designed for applications that operate across a wide temperature range, this polarized capacitor offers measurable high-frequency performance and long endurance for sustained operation up to 105°C.

Key Features

• Core Electricals — 330 µF nominal capacitance with ±20% tolerance and a rated voltage of 6.3 V, providing bulk charge storage for low-voltage circuits.
• High-Frequency Loss — tanδ (DF) of 0.21 measured at 20°C, 120 Hz, giving a quantified dissipation factor for design verification.
• Ripple Current Capability — Low-frequency ripple current of 230 mA (120 Hz) and high-frequency ripple current of 460 mA (100 kHz), supporting AC ripple handling across frequency ranges.
• Leakage — Rated leakage current of 20.79 µA, measured under standard conditions, for predictable standby and bias behavior.
• Reliability & Endurance — Life/endurance specified at 5000 hours and an operating temperature range of −40°C to +105°C for sustained high-temperature operation.
• Package & Mounting — Radial lead (can) package with φ6.3 × 11 mm dimensions and 2.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole assembly.
• Regulatory — RoHS compliant.

Typical Applications

• General Power Filtering — Bulk smoothing and decoupling on low-voltage power rails where compact, polarized capacitance is required.
• High-Frequency Ripple Reduction — Circuits requiring improved high-frequency impedance performance benefit from the UHV series’ lower impedance characteristics.
• Embedded and Consumer Electronics — Through-hole implementations needing a compact radial can and quantifiable endurance across −40°C to +105°C environments.

Unique Advantages

• Quantified Performance Metrics — Specified tanδ, leakage current, and ripple currents let engineers validate designs against measured values.
• Compact, Through-Hole Form Factor — φ6.3 × 11 mm can with 2.5 mm lead spacing enables space-efficient radial mounting and straightforward PCB integration.
• Wide Temperature Range — Rated for −40°C to +105°C, supporting designs exposed to significant ambient variation.
• High Ripple Handling — Distinct low- and high-frequency ripple current ratings (230 mA at 120 Hz, 460 mA at 100 kHz) support mixed-frequency power environments.
• Reliable Endurance — 5000-hour life rating at elevated temperature provides a defined baseline for long-term deployment planning.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.
