Introducing the WALSIN WSN series fixed resistors, designed for high reliability and precision in electronic applications. These thick film chip resistors are constructed with a high-grade ceramic body (aluminum oxide) and feature laser-trimmed resistive layers for accurate resistance values. Suitable for power supply, battery packs, DC-DC converters, and other power management circuits.
Suitable for immersion in solder baths up to 260°C for 10 seconds
Surface mount resistors are tested for solderability at 235°C for 2 seconds
Reliable solder joints can be achieved with standard infrared soldering profiles
Additional Information
Each resistor is marked with a 3- or 4-digit code indicating its resistance value. The resistors are designed to provide stable performance in demanding electronic environments.
For more detailed specifications and application guidelines, please refer to the datasheet.
Note: The RoHS compliance status is not specified. Please verify if RoHS compliance is required for your application.
