NOJA156M004RWJ

Overview

The NOJA156M004RWJ is a low-profile niobium oxide capacitor from the OxiCap series by KYOCERA AVX. It features a capacitance of 15 µF with a tolerance of ±20% and a DC voltage rating of 4 VDC. The component operates within a temperature range of -55°C to +105°C and exhibits an equivalent series resistance (ESR) of 2 Ohms. Physical dimensions are 3.2 mm in length, 1.6 mm in width, and 1.8 mm in height, conforming to the 1206 (3216 metric) package. Leakage current is specified at 1.8 µA, and it supports a ripple current of 212 mA.

Feature Summary

• Utilizes niobium oxide technology for stable performance across wide temperature ranges
• Low profile design suitable for space-constrained surface-mount applications
• High reliability with moisture sensitivity classification requiring controlled handling

Applications

• Portable consumer electronics requiring compact power filtering
• Automotive infotainment systems needing reliable decoupling
• Industrial equipment control circuits demanding stable capacitance

Procurement Notes

Verify RoHS compliance status and moisture sensitivity level prior to assembly. Confirm that the ordering suffix matches the required packaging format, as variations may exist between reel and cut tape options. Ensure storage conditions adhere to manufacturer guidelines to prevent degradation before soldering.

Selection Notes

Select this component when a 1206 footprint is required with 15 µF capacitance at 4 VDC. Consider the 2 Ohm ESR value for ripple current handling capabilities. Compare against tantalum alternatives if lower leakage or higher voltage ratings are necessary for the specific circuit topology.

Part Context

This part belongs to the NOJ series of niobium oxide capacitors, marketed under the OxiCap brand. It serves as an alternative to traditional tantalum capacitors, offering comparable electrical characteristics with improved surge current handling and reduced risk of thermal runaway in short-circuit scenarios.
