NOSD477M002R0035

Overview

The KYOCERA AVX NOSD477M002R0035 is a surface-mount Niobium Oxide capacitor from the OxiCap Low ESR series. It features a capacitance of 470 µF with a ±20% tolerance and a DC voltage rating of 2.5 VDC. The component exhibits a low equivalent series resistance (ESR) of 35 mOhms and a leakage current of 23.5 µA. Housed in a 2917 (7343 metric) package measuring 7.3 mm x 4.3 mm x 3.1 mm, it operates within a temperature range of -55°C to +125°C. The device supports a ripple current of 1.809 A and is supplied in reel packaging.

Feature Summary

• Low Equivalent Series Resistance (ESR) design for high-frequency performance
• High volumetric efficiency utilizing Niobium Oxide technology
• Extended operating temperature range suitable for demanding environments

Applications

• Smartphone and tablet power distribution networks
• Wearable device energy storage and filtering
• Communications module decoupling applications

Procurement Notes

Verify the specific suffix R0035 to confirm the 35 mOhm ESR specification, as other variants exist within the same series. Ensure compliance with Moisture Sensitivity Level 3 requirements during storage and handling. Confirm RoHS3 and REACH status prior to integration into final assemblies.

Selection Notes

Select this component when low impedance at high frequencies is critical for power integrity. Compare against tantalum alternatives for superior surge capability and lower ESR. Validate thermal management strategies given the 125°C maximum rating and self-heating effects under ripple current loads.

Part Context

This part belongs to the NOS series of Niobium Oxide capacitors, marketed under the OxiCap brand. It serves as an alternative to traditional solid tantalum capacitors, offering higher capacitance density and better pulse current handling capabilities in compact surface-mount packages.

Replacement Considerations

NOSD477M002R0055: Higher ESR variant (55 mOhms). NOSD477M002R0100: Higher ESR variant (100 mOhms). TAJC477M002RNJ: Solid Tantalum alternative with different physical dimensions and electrical characteristics.
