1537-40K Description

Short technical summary and product information.

The 1537-40K is a fixed inductor manufactured by API Delevan Inc. It features an inductance of 15 µH with ±10% tolerance and a rated current of 271 mA. The DC resistance is a maximum of 1.4 Ohm, ensuring efficient power handling for low-power circuits.

 

This inductor utilizes an iron core material in a molded, unshielded construction. It offers a high Q factor of 65 at 2.5 MHz and a self-resonant frequency of 40 MHz, making it suitable for RF applications up to tens of megahertz. The operating temperature range spans from -55°C to 105°C.

 

The package is an axial through-hole design with dimensions of 0.156 inches in diameter and 0.375 inches in length (3.96 mm x 9.53 mm). This makes it compatible with standard through-hole mounting techniques, suitable for prototyping and production environments.
