PM3604-33-B

Arrays, Signal Transformers Overview

The PM3604-33-B is an unshielded surface-mount inductor array manufactured by Bourns Inc. It contains two coils with a nominal inductance of 33 µH per coil. When connected in parallel, the total inductance is 33 µH with a rated current of 1.6 A and a maximum DC resistance of 78 mΩ. In series configuration, the inductance rises to 132 µH, the rated current drops to 800 mA, and the maximum DC resistance is 310 mΩ. The component operates within a temperature range of -55°C to 125°C and has a tolerance of ±20%.

Arrays, Signal Transformers Procurement Notes

Verify the specific suffix requirements for your application, as packaging options such as tape and reel or cut tape may vary by distributor. Confirm RoHS compliance status and lead times directly with authorized suppliers before finalizing orders. Ensure the selected variant matches the required current rating and inductance tolerance for your circuit design.

Arrays, Signal Transformers Selection Notes

Select this component when dual independent inductors are required in a single footprint. Choose the parallel configuration for higher current handling up to 1.6 A. Opt for the series configuration if higher inductance values near 132 µH are needed with lower current capacity. Verify that the unshielded nature does not interfere with nearby sensitive components due to potential magnetic field emission.

Arrays, Signal Transformers Part Context

This part belongs to the PM3600 series of inductor arrays from Bourns Inc. The series offers various inductance values and configurations to support diverse power management and signal integrity needs. The PM3604-33-B specifically provides a compact solution for applications requiring two matched inductors with defined thermal and electrical performance characteristics.

Arrays, Signal Transformers Replacement Considerations

Check for direct substitutes within the PM3600 series that offer similar inductance and current ratings. Ensure any replacement maintains the same package dimensions and pinout compatibility. Verify that alternative parts meet the same temperature and RoHS requirements.
