PT100R-1550HM

Fixed inductors have long been a staple in electronic components and have been used to introduce inductance into electrical circuits for a variety of uses. One such type of fixed inductor is the PT100R-1550HM, designed specifically for high-current applications. It is comprised of a ring core made of ferrite material, air gap, and solid steel flanges which together make up a unique symmetrical construction. It also utilizes multiple windings of high-grade copper enameled wire and silicone rubber insulation to ensure this construction remains intact.

The PT100R-1550HM is commonly used in the industrial sector to control current in electric motors, AC inverter drives, switching power supplies, and lighting projects. Its symmetrical construction works to evenly distribute current and prevents the formation of circulating currents. Its multiple isolated windings for each layer allow it to handle more current than regular single-layer inductors, making it ideal for high-current applications. The minimum core gap of 0.3mm ensures sufficient air flow for high-frequency applications, making it a great choice for high-frequency electronic applications as well.

In order to operate, current first travels through the core of the PT100R-1550HM. This current is then distributed across the multiple windings, causing an opposition to the current flow, thus creating inductance. This inductance will be determined by the number of windings and will tend to stay relatively constant, regardless of changes in the current. Due to the ring core construction, the inductance is also relatively low, typically 0.45~0.5mH.

All of these features mean that the PT100R-1550HM is a reliable and efficient choice for a variety of industrial applications. Its symmetrical construction provides for evenly distributed current flow, meaning you don’t have to worry about unwanted magnetic flux or circulating currents. Its multiple windings allow for excellent current handling capabilities, and it’s minimum gap ensures excellent high-frequency performance. Overall, the PT100R-1550HM is an ideal choice for those needing an efficient and reliable fixed inductor.
