UHW1J331MPD

The UHW1J331MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic designs. It combines a 330 µF capacitance with a 63 V rating and is optimized for applications that require high ripple current handling and low impedance in a compact package.

Standard features include a wide operating temperature range (−40°C to +105°C), a long endurance rating (12,000 hours at 105°C), and RoHS compliance, making the part suitable for designs prioritizing durability and regulatory conformity.

Key Features

• Electrical Performance — 330 µF nominal capacitance with ±20% tolerance and a rated voltage of 63 V, providing stable bulk capacitance for power-related circuits.
• Low Impedance — Rated impedance of 280 mΩ helps reduce voltage ripple and power loss in high-current conditions.
• High Ripple Current Capability — Low-frequency ripple current of 995 mA at 120 Hz and high-frequency ripple current of 1.99 A at 10 kHz, enabling reliable operation under varying ripple profiles.
• Loss and Leakage Characteristics — tan δ of 0.09 measured at 20°C, 120 Hz, and typical leakage current specified as 207.9 µA, allowing predictable dissipation and standby leakage behavior.
• Reliability and Lifetime — Endurance rated for 12,000 hours at 105°C with specified limits for capacitance change, tan δ, and leakage after the test period.
• Mechanical & Packaging — Compact radial-can package (φ10 × 25L) with 5 mm lead spacing (±0.5 mm) and bulk/bag packing options; polarity-marked sleeve for assembly clarity.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General Purpose Electronics — A general-purpose radial-lead electrolytic solution where a 330 µF, 63 V capacitor is required for energy storage and smoothing.
• Power Supply Filtering — Useful in circuits that benefit from low impedance and high ripple current capability to stabilize supply rails.
• Decoupling and Bulk Storage — Provides bulk capacitance for boards with moderate to high ripple loads while occupying a small radial-can footprint.

Unique Advantages

• Compact, High-Capacity Package — φ10 × 25L can delivers 330 µF in a small radial form factor, saving board space while retaining useful bulk energy storage.
• High Ripple Handling — Specified ripple currents (995 mA at 120 Hz; 1.99 A at 10 kHz) allow the capacitor to address both low- and high-frequency ripple demands.
• Predictable Loss Characteristics — Low tan δ (0.09 at 20°C, 120 Hz) supports predictable power dissipation in AC conditions.
• Long Endurance — 12,000-hour rated life at 105°C supports designs that require extended service life under elevated temperature stress.
• Ease of Assembly — Radial lead configuration with 5 mm lead spacing and clear polarity marking simplifies through-hole placement and manual or automated insertion.
• Regulatory Compliance — RoHS conformity supports deployment in regions requiring restricted-substance compliance.
