Overview of SQZW103R3J by TE Connectivity

The SQZW103R3J is a fixed resistor designed with a wire wound construction, making it suitable for applications requiring precision resistive values and stability across a range of conditions. This part has a resistance value of 3.3 ohms and is rated for a power dissipation of 10 watts. The tolerance of the resistor is ±5%, allowing for a reasonable degree of deviation from the specified resistance value.

In terms of temperature coefficients, the SQZW103R3J has a rating of 300 ppm/°C. This relatively moderate temperature coefficient indicates that the resistor’s resistance will change by 0.03% for each degree Celsius of temperature change, which may be appropriate for various everyday applications in stable environments. The resistor operates within a temperature range of -55 °C to 250 °C, making it versatile for different operational conditions.

The physical dimensions of the SQZW103R3J are compact, with a rectangular package that measures 48 mm in length, 10 mm in width, and 10 mm in height. It features a through-hole mounting style as well, which can be advantageous for connections on printed circuit boards. Designed with a lead spacing of 32 mm, it has two terminals shaped in a snap-in configuration for secure mounting and connectivity.

This part is part of the Wire Wound Resistors subcategory within the broader resistors category, and is compliant with both RoHS and REACH regulations, ensuring its suitability for environmentally-sensitive projects. As of the current writing, the factory lead time for this part is approximately 20 weeks and two days, which may be relevant for procurement planning.
