WB1008TR33SJ

Fixed Inductors Overview

The WB1008TR33SJ is a general-purpose wirewound inductor manufactured by Cal-Chip Electronics, Inc. It features an inductance of 0.33 µH with a tolerance of ±5%. The component is designed for surface-mount installation in a 1210 (3225 metric) package. Key electrical specifications include a maximum DC resistance of 0.24 Ω and a self-resonant frequency of 190 MHz. It supports a maximum rated current of 0.5 A and maintains a minimum quality factor of 30 at the nominal inductance. The device operates within a temperature range of -20°C to 100°C.

Fixed Inductors Feature Summary

• Utilizes leadless wound chip construction with metal tab electrodes for enhanced leaching resistance.
• Coils are encapsulated in heat-proof resin to ensure high dimensional accuracy and mechanical shock resistance.
• Offers high reliability and stability against heat and humidity variations.

Fixed Inductors Applications

• RF circuit filtering
• General-purpose signal processing
• High-density electronic circuit mounting

Fixed Inductors Procurement Notes

Verify the specific suffix 'SJ' against the manufacturer's official documentation to confirm packaging details and terminal plating specifications. Ensure that the thermal operating limits (-20°C to 100°C) align with the target application environment. Cross-reference the 1210 footprint dimensions with the PCB layout guidelines provided in the official datasheet to guarantee proper solder joint integrity during assembly.

Fixed Inductors Selection Notes

Select this component when a compact 1210 form factor is required for RF or general-purpose applications. The 0.33 µH value and 0.5 A current rating suit low-power signal paths. Consider the 190 MHz self-resonant frequency to ensure performance remains stable within the intended operational bandwidth. Verify compatibility with automated surface-mount assembly processes due to the molded resin body design.

Fixed Inductors Part Context

This part belongs to the NL series of molded chip wirewound inductors from Cal-Chip Electronics. The series is engineered for automatic mounting in high-density circuits. The NL3225 type designation corresponds to the 1210 package size. The product line emphasizes reliability through heat-resistant resin encapsulation and durable metal terminal electrodes.

Fixed Inductors Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the NL3225TR33JLF from the same manufacturer. Other compatible options may include parts from YAGEO with matching 0.33 µH inductance and 1210 footprint, subject to verification of DC resistance and current ratings against original specifications.
