NOSD477M002R0055

Overview

The NOSD477M002R0055 is a Niobium Oxide capacitor from the OxiCap Low ESR series by KYOCERA AVX. It features a capacitance of 470 µF with a ±20% tolerance and a DC voltage rating of 2.5 VDC. The component exhibits an equivalent series resistance (ESR) of 55 mOhms and supports a ripple current of 1.809 A. Housed in a 2917 (7343 Metric) surface-mount package, it measures 7.3 mm in length, 4.3 mm in width, and 2.9 mm in height. The device operates within a temperature range of -55°C to +125°C and has a maximum leakage current of 23.5 µA.

Feature Summary

• Utilizes niobium oxide technology to provide high volumetric efficiency compared to traditional tantalum capacitors.
• Features low equivalent series resistance (ESR) characteristics suitable for high-frequency decoupling applications.
• Offers enhanced reliability and stability against thermal runaway conditions inherent in solid electrolyte capacitors.

Applications

• Smartphone and tablet power distribution networks
• Wearable device circuitry requiring compact energy storage
• Consumer equipment such as flat TVs and PCs

Procurement Notes

Verify compliance with RoHS3 specifications and REACH regulations prior to integration. Confirm moisture sensitivity level (MSL 3) handling requirements during assembly. Ensure the selected variant matches the specific ESR and voltage ratings required for the target application design constraints.

Selection Notes

Select this component when high capacitance density is required in a 2917 footprint. Consider the 2.5V rating and 55mOhm ESR for low-voltage digital loads. Evaluate the operating temperature range up to 125°C against system thermal profiles to ensure long-term reliability under stress conditions.

Part Context

This part belongs to the NOS series of OxiCap capacitors, representing a shift toward niobium-based solutions. It serves as an alternative to tantalum capacitors in space-constrained portable electronics. The series emphasizes reduced risk of failure modes associated with higher voltage ratings while maintaining robust performance in mobile devices.

Replacement Considerations

NOSD477M002R0100: Offers identical capacitance and voltage but with a higher ESR of 100 mOhms.
