OA180K Description

Short technical summary and product information.

The Ohmite OA180K is a carbon composition resistor with a power rating of 1 watt and a resistance value of 18 ohms. It belongs to the OA series, characterized by molded insulation and suitability for applications demanding high surge and pulse-withstanding capabilities.

Carbon composition resistors like the OA180K are known for their robustness against surges. However, for modern circuit designs, engineers may consider alternatives such as high-power metal film or ceramic composition resistors, depending on specific thermal and pulse requirements. Careful selection should always involve verification against datasheet parameters, including peak pulse voltage, power derating curves, and moisture sensitivity levels.

This component is supplied in a '插件' package. While the OA180K is listed as RoHS3 Compliant, the MSL is rated as 1 Unlimited, and REACH status is Unaffected, these compliance details are based on low-confidence sources and should be verified.
