Overview
The Bourns SRF3225TP-102Y is a shielded surface-mount common mode choke designed for automotive applications. It features a ferrite core and measures 3.2 x 2.5 x 2.2 mm. The component provides an impedance of 1000 Ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1.5 A and has a maximum DC resistance of 100 mOhms. The operating temperature range spans from -40°C to +105°C.
Feature Summary
- Shielded construction minimizes electromagnetic interference coupling
- Ferrite core material ensures stable inductance characteristics
- Surface mount design facilitates automated PCB assembly
Applications
- Automotive electronic circuits
- Signal line filtering
- Power supply noise suppression
Procurement Notes
Verify the specific suffix 'Y' against the manufacturer's official datasheet to confirm packaging details and exact electrical tolerances. Ensure the procurement documentation matches the required automotive qualification standards if applicable. Cross-reference the impedance value at 100 MHz with system requirements to validate performance suitability.
Selection Notes
Select this component when space constraints require a 3225 package size. The 1.5 A current rating suits moderate power lines. Verify that the 1000 Ohm impedance at high frequencies aligns with the target noise spectrum. Confirm that the 105°C maximum operating temperature meets the environmental conditions of the installation site.
Part Context
This part belongs to the SRF3225TP series of shielded common mode chokes from Bourns. The series offers various impedance values within the same physical footprint. The 'TP' designation indicates the shielded type, while '102' specifies the impedance code. This series targets compact electronics requiring effective noise reduction.
Replacement Considerations
Check for direct substitutes within the SRF3225TP series with matching 1000 Ohm impedance. Verify pin compatibility and thermal ratings before substituting with other manufacturers' 3225 package chokes.
