Housed in a 1210 (3528 metric) surface-mount package, it measures 3.5 mm x 2.8 mm x 2.1 mm. Key electrical parameters include an ESR of 1.5 Ohms, leakage current of 5.4 µA, and ripple current capability of 261 mA. The component operates within a temperature range of -55°C to +105°C.

Feature Summary

• Utilizes niobium oxide technology for high volumetric efficiency compared to tantalum alternatives.
• Features a low-profile 1210 case design suitable for space-constrained surface-mount applications.
• Provides stable performance across a wide operating temperature range of -55°C to +105°C.

Applications

• Smart metering systems
• Industrial equipment power supplies
• Consumer electronics circuitry

Procurement Notes

Verify the specific ordering suffix 'WJ' against the manufacturer datasheet to confirm packaging configuration and compliance status. Ensure the requested quantity matches available reel or cut-tape options. Confirm RoHS3 compliance requirements are met for the target assembly process. Cross-reference the manufacturer part number with distributor catalogs to ensure accurate sourcing.

Selection Notes

Select this component when high capacitance density is required in a 1210 footprint. Consider the 4V rating and 1.5 Ohm ESR for filtering applications. Compare against tantalum equivalents like TAJA686M004RNJ if higher temperature ratings or different form factors are needed. Evaluate thermal management needs given the 105°C maximum operating limit.

Part Context

This part belongs to the OxiCap NOJ series, representing KYOCERA AVX's niobium oxide capacitor line. These components serve as alternatives to traditional solid tantalum capacitors, offering similar electrical characteristics with improved safety profiles regarding failure modes. The series is designed for general-purpose decoupling and filtering in modern electronic assemblies.

Replacement Considerations

TAJA686M004RNJ is a tantalum alternative with identical capacitance and voltage but differs in case size (1206 vs 1210) and temperature rating (+125°C vs +105°C). Verify footprint compatibility before substitution due to dimensional differences between the two technologies.
