URZ1J331MHD

The URZ1J331MHD is a radial‑lead aluminum electrolytic capacitor from Nichicon's URZ series, rated at 330 µF and 63 V. It is a compact, low‑profile polarized capacitor designed for general‑purpose applications that require bulk capacitance and stable performance across a wide temperature range.

This part offers specified ripple current capability at both low and high frequencies, defined leakage current, and a 1,000‑hour endurance at elevated temperature, making it suitable where reliable energy storage and filtering are needed in compact PCB layouts.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±20% tolerance and a rated voltage of 63 V, providing measurable bulk storage for power rails and decoupling.
• Temperature Range & Endurance — Operates from −55°C to +105°C with a specified lifetime of 1,000 hours at 105°C, enabling use in designs that require wide thermal capability and defined high‑temperature endurance.
• Ripple Current Performance — Low‑frequency ripple current 510 mA (120 Hz) and high‑frequency ripple current 765 mA (10 kHz), supporting AC ripple handling across common power‑supply frequencies.
• Leakage Current — Specified leakage current of 623.7 µA, measured per the product data conditions for predictable DC leakage behavior.
• Compact Radial Package — Small can size φ12.5 × 15 mm (D × L) / 1.25 cm × 1.5 cm with 5.0 mm lead spacing (±0.5 mm), 0.6 mm lead diameter for the 12.5 mm case, suited to compact PCB footprints and through‑hole assembly.
• Packaging & Production Status — Available in bulk (no terminal forming) and bag packing; part is in mass production for predictable supply.

Typical Applications

• General Purpose Electronics — Employed where general‑purpose bulk capacitance is required in power rails, board‑level filtering, or energy storage.
• Power Supply Filtering — Sized to handle defined ripple currents at 120 Hz and 10 kHz, making it applicable for smoothing and ripple suppression in power modules.
• Compact Through‑Hole Designs — Low‑profile φ12.5 × 15 mm can and radial leads with 5 mm spacing fit tightly constrained PCB layouts while providing electrolytic capacitance.

Unique Advantages

• Wide Operating Temperature Range: Rated from −55°C to +105°C, supporting designs exposed to varying thermal environments without losing specified performance.
• Defined High‑Temperature Endurance: 1,000 hours at 105°C provides clear expectations for life testing and reliability planning in elevated‑temperature applications.
• Frequency‑Aware Ripple Handling: Provided ripple current ratings for both 120 Hz (510 mA) and 10 kHz (765 mA) let designers assess suitability for both line‑frequency and higher‑frequency switching environments.
• Predictable Leakage Behavior: Specified leakage current value (623.7 µA) aids in calculating standby losses and bias requirements for precision or low‑current designs.
• Compact Footprint with Standard Leads: φ12.5 mm can, 15 mm length and 5.0 mm lead spacing (±0.5 mm) simplify mechanical integration in through‑hole assemblies and fixtures.
• Production and Packaging Options: Mass production availability and bulk/bag packing choices support volume procurement and assembly workflows.
