1537-51K Description

Short technical summary and product information.

The 1537-51K is a molded, unshielded wirewound inductor from API Delevan Inc. It features an inductance of 33 µH with a tolerance of ±10%. The DC current rating is 185 mA with a maximum DC resistance of 3 Ohm. The self-resonant frequency is 19 MHz, and the Q factor is 65 at 2.5 MHz. Constructed with an iron core, it is unshielded and suitable for applications where magnetic shielding is not critical. The operating temperature range is -55°C to 105°C. The component is housed in an axial package with a diameter of 0.156 inches and length of 0.375 inches (3.96mm x 9.53mm), designed for through-hole mounting. This inductor is commonly used in filtering, RF circuits, and general-purpose inductive applications.
