SFSKA4M50CF00-R3

Overview

The SFSKA4M50CF00-R3 is a ceramic filter with a center frequency of 4.5 MHz and a bandwidth of 60 kHz. It features a 1 kOhm impedance and operates in a 6-SMD, No Lead package. The component has a maximum thickness of 1.4 mm and a mounting area of 3.45 x 3.1 mm. It provides 6 dB insertion loss and 20 dB attenuation.

Feature Summary

• Slim profile with a maximum thickness of 1.4 mm
• Small mounting footprint of 3.45 x 3.1 mm
• Compatible with automatic placement equipment

Applications

• TV signal filtering
• VCR signal discrimination
• General-purpose signal filtering

Procurement Notes

Verify the specific datasheet version on the Murata official website to ensure compatibility with current design requirements. Confirm that the 6-SMD no-lead package dimensions align with the PCB layout. Check for any recent updates to the RoHS compliance status or manufacturing location before finalizing procurement orders.

Selection Notes

Select this component when a narrow 60 kHz bandwidth is required at 4.5 MHz. The low profile and small size make it suitable for space-constrained designs. Ensure the circuit can accommodate the 1 kOhm impedance and 6 dB insertion loss characteristics typical of this discriminator filter type.

Part Context

This part belongs to the CERAFIL series from Murata Electronics. It is designed as a slim, surface-mount ceramic filter. The series is commonly used in consumer electronics applications requiring precise frequency discrimination and filtering at intermediate frequencies.
