LTCV10.7MA19

Overview

The LTCV10.7MA19 is a ceramic band-pass filter manufactured by Transko Electronics, Inc., designed for intermediate frequency applications. It operates at a center frequency of 10.7MHz with a nominal 3dB bandwidth of ±175kHz and a 20dB bandwidth of 950kHz. The component features a characteristic impedance of 470Ω and is housed in a compact 3-SMD, no-lead package with dimensions of 3.0mm x 1.5mm. This device serves as a drop-in replacement for discontinued Murata SFSCE, SFECF, SFECV, and SFECK series filters, maintaining fit, form, and function compatibility.

Feature Summary

• Provides precise band-pass filtering at the standard 10.7MHz intermediate frequency
• Offers direct physical and electrical compatibility with specific discontinued Murata ceramic filter series
• Utilizes a compact surface-mount package suitable for space-constrained circuit designs

Applications

• Intermediate frequency stages in FM radio receivers
• Consumer electronics requiring 10.7MHz signal processing
• Replacement components for legacy equipment utilizing Murata SFSCE/SFECF/SFECV/SFECK filters

Procurement Notes

Verify that the target application specifically requires a 10.7MHz ceramic filter with 470Ω impedance. Confirm that the 3-SMD no-lead package dimensions align with the existing PCB footprint. Ensure the design accounts for the ±175kHz bandwidth to meet system selectivity requirements. Cross-reference the part number against current availability lists as it replaces older Murata inventory.

Selection Notes

Select this component when a 10.7MHz ceramic filter is required for intermediate frequency applications. It is particularly suitable for designs needing to replace discontinued Murata SFSCE, SFECF, SFECV, or SFECK series parts due to its identical fit, form, and function characteristics. Consider the 470Ω impedance match for the surrounding circuitry.

Part Context

Transko Electronics manufactures the LTCV series of ceramic filters, which are engineered to replace specific discontinued components from other manufacturers. The LTCV10.7MA19 is part of this lineup, offering a standardized solution for 10.7MHz applications. These filters are designed to provide reliable performance in consumer electronics and communication devices where stable intermediate frequency filtering is critical.

Replacement Considerations

This component is explicitly documented as a drop-in replacement for Murata models SFSCE, SFECF, SFECV, and SFECK. Verify that the original design utilized one of these specific Murata part numbers to ensure compatibility.
