Overview
The LFCW-1142+ is a low pass filter manufactured by Mini-Circuits, utilizing Low Temperature Co-fired Ceramic (LTCC) technology. It operates with a cutoff frequency of 11.7 GHz and features a 50 Ohm impedance. The component is housed in a compact 0603 surface mount package, measuring 1.6 x 0.8 mm with a maximum height of 0.024 inches (0.61 mm). Electrical specifications include an insertion loss of 2.6 dB and a typical stop band rejection of 20 dB.
Feature Summary
- Multilayer LTCC construction for high reliability
- Compact 0603 footprint enabling high circuit board layout density
- Minimizes parasitic effects due to small physical size
Applications
- WiFi systems
- Wireless communication circuits
- RF signal conditioning
Procurement Notes
Verify the specific part number suffix against official Mini-Circuits documentation to ensure correct configuration. Confirm that the required electrical parameters, such as cutoff frequency and impedance, align with your system design requirements before procurement. Ensure compatibility with standard surface mount assembly processes given the 0603 package dimensions.
Selection Notes
Select this component when a low profile, high-density surface mount solution is required for frequencies up to 11.7 GHz. The LTCC technology offers robust performance in a minimal footprint. Consider the 2.6 dB insertion loss and 20 dB stop band rejection when evaluating signal integrity needs for wireless applications.
Part Context
This component belongs to Mini-Circuits' LFCW series of ceramic filters. These filters are designed for surface mount applications, offering a balance between performance and size. The LTCC construction allows for integration into modern electronic devices where space constraints are critical.
Replacement Considerations
Consult Mini-Circuits official substitution guides for verified alternatives. Cross-reference cutoff frequency and package dimensions to ensure mechanical and electrical compatibility without modifying the existing circuit design.
