URZ0J103MHD

The URZ0J103MHD is a 10,000 µF polarized aluminum electrolytic capacitor in a radial-lead can, designed for general-purpose low-voltage applications. It combines very high capacitance in a compact φ18 × 20 mm package with a wide operating temperature range and defined ripple-current capability to support energy storage and smoothing in 6.3 V DC circuits.

This part is manufactured by Nichicon as part of the URZ series and is specified for long-term endurance at elevated temperature, making it suitable where large bulk capacitance and predictable behavior over temperature are required.

Key Features

• Capacitance: 10,000 µF nominal capacitance provides significant bulk energy storage for low-voltage DC circuits.
• Rated Voltage: 6.3 V DC rating for low-voltage applications and systems.
• Capacitance Tolerance: ±20% tolerance at 120 Hz, 20 °C for predictable sizing in designs.
• Loss Tangent (tan δ): Specified tan δ of 0.10 (measured at 20 °C, 120 Hz) for defined dissipation characteristics.
• Ripple Current Capability: Low-frequency ripple current 1.45 A at 120 Hz and high-frequency capability 1.6675 A at 10 kHz to handle AC stress in filtering and smoothing roles.
• Leakage Current: Specified leakage current of 1,890 µA (per provided measurement condition) for predictable standby and bias behavior.
• Temperature & Endurance: Rated for −55 °C to +105 °C with 1,000 hours endurance at 105 °C, supporting elevated-temperature operation with defined lifetime.
• Package & Mounting: Radial-lead can with φ18 × 20 mm body and 7.5 mm lead spacing (±0.5 mm), suitable for through-hole radial mounting and straightforward PCB placement.
• Packaging Options: Available in bulk (no terminal forming) or bag packing to suit production and prototyping needs.
• Product Status: End Of Life — consult sales for availability and last-time-buy options.

Typical Applications

• Low-voltage power supplies: Bulk smoothing and energy storage in 6.3 V regulator and supply rails where large capacitance is required to reduce ripple.
• Power filtering for embedded systems: Local energy reserve and decoupling for modules and assemblies that operate at low DC voltages.
• Pulsed or hold-up energy storage: Short-term energy buffering in circuits that require rapid discharge from a compact capacitor, leveraging the 10,000 µF value.
• General-purpose electronic equipment: Where high-capacitance, radial-lead electrolytics are specified and a wide temperature range (−55 °C to +105 °C) is needed.

Unique Advantages

• Very high capacitance in a compact can: 10,000 µF in a φ18 × 20 mm package reduces board area compared with multiple smaller capacitors.
• Defined ripple performance: Rated ripple currents of 1.45 A (120 Hz) and 1.6675 A (10 kHz) allow designers to specify AC stress capability explicitly.
• Wide temperature endurance: Specified operation from −55 °C to +105 °C with 1,000 hours endurance at 105 °C supports elevated-temperature deployments with known lifetime.
• Through-hole radial format: 7.5 mm lead spacing and a radial can simplify assembly for hand-soldering and wave/through-hole processes.
• Clear electrical parameters: Stated leakage current (1,890 µA) and tan δ (0.10 at 20 °C, 120 Hz) make electrical budgeting and thermal design more predictable.
• Packaging flexibility: Bulk or bag packing options accommodate both prototype and production workflows.
