SRF0502-142Y

Overview

The Bourns SRF0502-142Y is a shielded common mode filter choke from the SRF0502 series, designed for surface mount PCB assembly. It features a ferrite core and measures 5 mm x 5 mm x 2.5 mm. The component provides an inductance of 2.6 uH with a tolerance of +/-35% and a DC resistance of 55 mOhms. It supports a maximum DC current of 1.5 A and operates within a temperature range of -40 C to +125 C. Impedance is rated at 1.4 kOhms at 100 MHz.

Feature Summary

Shielded construction minimizes electromagnetic interference radiation
Low profile design facilitates compact circuit board layouts
Ferrite core material ensures effective high-frequency noise suppression

Applications

EMI Suppression
Line Filters
Consumer Electronics

Procurement Notes

Verify the specific impedance value of 1.4 kOhms at 100 MHz against your circuit requirements. Confirm the 1.5 A current rating is sufficient for your application's peak loads. Check that the 55 mOhm DC resistance aligns with your power loss constraints. Ensure the 5x5x2.5 mm footprint matches your PCB layout. Validate RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when space-constrained designs require shielded common mode chokes. The 2.6 uH inductance suits moderate filtering needs. The 1.5 A rating fits low-to-medium current signal lines. Consider the 100 MHz impedance specification for high-frequency noise profiles. The SMD package simplifies automated assembly processes compared to through-hole alternatives.

Part Context

This part belongs to the Bourns SRF0502 series of surface mount common mode chokes. The series offers various inductance and impedance options within a standardized 5x5 mm footprint. These components are engineered for EMI suppression in portable and industrial electronics. The shielded design distinguishes them from unshielded counterparts in similar form factors.
