Bourns introduces two additional series of High Current, Shielded Power Inductors - Models SRP5030T and SRP6540. Bourns now off ers a total of sixteen SRP models. The Model SRP5030T and SRP6540 Shielded Power Inductor Series are designed with molded construction of an iron powder core that offers a compact size, low DC resistance, high current carrying capability and magnetically shielded features.

These inductors are ideal for use in DC/DC converters for mobile electronic devices, computers, data storages and voltage regulator modules. Th e low DC resistance feature makes them especially attractive for mobile electronic device applications with prolonged battery life where low power dissipation is essential. The magnetically shielded construction of the SRP Series has low radiation that is ideal for high density board assembly.

The Bourns Model SRP5030T Series offers a 5.7 x 5.2 mm footprint in a 2.8 mm height with an inductance range of 0.33 – 10 μH, heat rating current up to 14 A, and saturation current up to 18 A. The operating temperature range is from -40 to +125 °C.

The Bourns Model SRP6540 Series off ers a 7.2 x 6.5 mm footprint in a 4 mm height, an inductance range of 0.56 – 47 μH with both heat rating and saturation current up to 18 A. Th e operating temperature range is from -55 to +125 °C.
