NOJA475M010RWJ

Overview

The NOJA475M010RWJ is a low-profile Niobium Oxide capacitor from the Oxicap series, manufactured by KYOCERA AVX. It features a capacitance of 4.7 uF with a voltage rating of 10 VDC and a tolerance of ±20%. The component utilizes an SMD/SMT endowment in a 1206 (3216 metric) package, measuring 3.2 mm in length, 1.6 mm in width, and 1.8 mm in height. Key electrical parameters include an ESR of 3.1 Ohms, a ripple current rating of 170 mA, and a leakage current of 1 uA. It operates within a temperature range of -55 C to +105 C.

Feature Summary

• Utilizes niobium oxide dielectric technology for stable performance.
• Designed as a low-profile surface mount device for space-constrained applications.
• Offers high volumetric efficiency compared to traditional tantalum capacitors.

Applications

• General purpose decoupling and bypassing in electronic circuits.
• Power supply filtering for portable devices.
• Signal conditioning in consumer electronics.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to ensure correct packaging and tape specifications. Confirm that the requested quantity aligns with standard reel or cut-tape availability. Cross-reference the date code and lot number upon receipt to ensure compliance with project timeline requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to soldering.

Selection Notes

Select this component when a compact surface mount solution is required with higher capacitance density than tantalum alternatives. The 1206 footprint provides a balance between size and electrical performance. Consider the 105 C maximum operating temperature for thermal management planning. The low ESR value supports applications requiring moderate ripple current handling capabilities.

Part Context

This part belongs to the NOJ series of Niobium Oxide capacitors, marketed under the Oxicap brand name. It serves as an alternative to solid tantalum capacitors, offering improved surge current handling and lower cost per microfarad. The series is designed for general-purpose applications where reliability and small form factor are critical design constraints.

Replacement Considerations

TAJA475M010RNJ is a confirmed substitute part number from the same manufacturer, though it is a Tantalum type with different electrical characteristics such as higher ESR and leakage current. Verify compatibility regarding ESR, leakage, and physical dimensions before substitution.
