NOJA685M006RWJ

Overview

The KYOCERA AVX NOJA685M006RWJ is a surface-mount Niobium Oxide capacitor from the OxiCap NOJ series. It features a nominal capacitance of 6.8 µF with a ±20% tolerance and a DC voltage rating of 6.3 V. The component utilizes a 1206 (3216 metric) package, measuring 3.2 mm in length, 1.6 mm in width, and 1.8 mm in height. Key electrical specifications include a maximum equivalent series resistance (ESR) of 2.6 ohms at 100 kHz, a dissipation factor of 6% at 120 Hz, and a maximum leakage current of 1.1 µA at rated voltage. It supports a ripple current of 186 mA and operates within a temperature range of -55°C to +105°C.

Feature Summary

• Utilizes niobium oxide dielectric technology for high volumetric efficiency compared to traditional tantalum capacitors.
• Provides stable performance across a wide operating temperature range extending up to +105°C.
• Features low profile SMD construction suitable for space-constrained surface mount applications.

Applications

• Smart meter circuitry requiring reliable decoupling and filtering.
• Alternate energy system power management modules.
• Industrial equipment control boards needing robust surface-mount capacitance.

Procurement Notes

Verify the specific suffix 'RWJ' against the official Kyocera AVX datasheet to confirm reel packaging and lead-free compliance. Ensure the ordered quantity matches the manufacturer's standard reel size. Confirm that the application voltage does not exceed the 6.3 VDC rating under all surge conditions. Cross-reference the ESR value of 2.6 ohms with circuit simulation requirements to prevent thermal issues.

Selection Notes

Select this component when higher capacitance density than tantalum is required in a 1206 footprint. The 6.3 V rating suits low-voltage digital logic and analog signal conditioning. Consider the 2.6 ohm ESR for ripple current handling capabilities. The -55°C to +105°C range allows use in harsh industrial environments where standard ceramic capacitors might fail due to microphonics or aging.
