Overview
The KYOCERA AVX NOJA476M004RWJ is a low-profile Niobium Oxide capacitor from the Oxicap series. It offers a capacitance of 47 uF with a DC voltage rating of 4 VDC and a tolerance of 20%. The component features an ESR of 2.2 Ohms and operates within a temperature range of -55 C to +105 C. Housed in a 1206 (3216 metric) SMD package measuring 3.2 mm x 1.6 mm x 1.8 mm, it supports a ripple current of 202 mA and has a leakage current of 3.8 uA.
Feature Summary
- Utilizes niobium oxide technology for high volumetric efficiency compared to traditional tantalum capacitors.
- Features a low-profile surface mount design suitable for space-constrained applications.
- Provides stable electrical performance across a wide operating temperature range.
Applications
- Portable consumer electronics requiring compact power filtering
- Mobile communication devices
- Wearable technology
Procurement Notes
Verify the specific suffix RWJ against official datasheets to confirm packaging and moisture sensitivity levels. Ensure compliance with RoHS directives and check humidity sensitivity classification prior to storage and reflow soldering processes.
Selection Notes
Select this component when higher capacitance density than tantalum is required in a 1206 footprint. Consider the 2.2 Ohm ESR and 202 mA ripple current limits for circuit stability. Verify thermal requirements against the 105 C maximum operating limit.
Part Context
This part belongs to the NOJ series of Niobium Oxide capacitors marketed under the Oxicap brand. It serves as an alternative to solid tantalum capacitors, offering similar form factors but with different material properties and electrical characteristics suited for modern miniaturized electronics.
Replacement Considerations
TAJA476M004RNJ is a comparable tantalum option in the same package. NOJD477M004RWJ offers higher capacitance in a larger 2917 package. Verify pin compatibility and electrical ratings before substitution.
FAQ
