NOJB336M004RWJ

Overview

The NOJB336M004RWJ is a Niobium Oxide capacitor from the OxiCap series by KYOCERA AVX. It features a capacitance of 33 uF with a DC voltage rating of 4 VDC and a tolerance of 20%. The component utilizes a 2312 (6032 metric) surface mount package, measuring 6 mm in length, 3.2 mm in width, and 2.8 mm in height. Key electrical specifications include an equivalent series resistance (ESR) of 500 mOhms and a leakage current of 6.6 uA. It supports a ripple current of 514 mA and operates within a temperature range of -55 C to +105 C.

Feature Summary

• Utilizes niobium oxide technology for solid dielectric performance
• Designed for high reliability in surface mount applications
• Supports low impedance requirements through defined ESR characteristics

Applications

• General purpose decoupling in electronic circuits
• Power supply filtering applications
• Portable consumer electronics requiring compact form factors

Procurement Notes

Verify the specific ordering suffix against official KYOCERA AVX documentation to ensure correct packaging and terminal configuration. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure that the selected variant matches the required thermal and electrical ratings for the target application environment.

Selection Notes

Select this component when a solid niobium oxide capacitor is preferred over tantalum alternatives due to inherent surge current handling capabilities. Consider the 2312 package dimensions for board space constraints. Evaluate the 500 mOhm ESR against circuit ripple current requirements to ensure stable operation under load conditions.

Part Context

This part belongs to the OxiCap family of niobium oxide capacitors manufactured by KYOCERA AVX. These components are positioned as alternatives to traditional tantalum capacitors, offering similar capacitance densities with improved safety margins regarding short-circuit events. The product line targets modern electronics manufacturing where reliability and size efficiency are critical.

Replacement Considerations

Direct substitutes may include other niobium oxide capacitors from KYOCERA AVX with matching case codes and ratings. Cross-referencing with standard tantalum equivalents requires careful evaluation of surge current limits and ESR differences to prevent circuit instability.
