NOJD477M002SWJ

Overview

The NOJD477M002SWJ is a Niobium Oxide capacitor from the KYOCERA AVX NOJ series, designed for surface-mount applications. It features a capacitance of 470 µF with a DC voltage rating of 2.5 VDC and a tolerance of ±20%. The component exhibits an Equivalent Series Resistance (ESR) of 300 mOhms and operates within a temperature range of -55°C to +105°C. Housed in a 2917 (7343 metric) case size measuring 7.3 mm in length, 4.3 mm in width, and 3.1 mm in height, it utilizes SMD/SMT terminations.

Feature Summary

• Utilizes niobium oxide technology to provide high volumetric efficiency compared to traditional tantalum capacitors.
• Features low profile construction suitable for space-constrained surface-mount designs.
• Offers stable electrical performance across a wide operating temperature range.

Applications

• Portable consumer electronics requiring compact power filtering
• Industrial control systems utilizing surface-mount assembly
• General-purpose DC-DC converter output decoupling

Procurement Notes

Verify current availability status directly with authorized distributors or the manufacturer, as niobium oxide components may have specific supply chain constraints. Confirm that the ordering suffix corresponds to the required packaging format and terminal finish specifications for your production line. Ensure compliance with RoHS directives and check for any relevant environmental declarations prior to final procurement authorization.

Selection Notes

Select this component when high capacitance density is required in a 2917 package footprint without the risk of thermal runaway associated with solid tantalum. The 2.5V rating and 300mOhm ESR make it suitable for low-voltage digital logic supplies. Compare leakage current specifications against system requirements to ensure adequate standby power management.

Part Context

This part belongs to the NOJ Low Profile Niobium Oxide Capacitor series by KYOCERA AVX. It serves as an alternative to tantalum capacitors in applications where reliability and volume efficiency are critical. The Oxicap branding indicates its position within the company's niobium oxide product line, offering distinct electrical characteristics compared to standard MLCC or tantalum solutions.

Replacement Considerations

Direct substitutes include NOSD477M002R0055 for lower ESR requirements and NOJE477M002RWJ for higher ripple current handling. Verify pin compatibility and thermal derating curves when swapping between different niobium oxide series or manufacturers.
