Overview

Mini-Circuits LFCN LTCC Low Pass Filters offer a 50Ω impedance rating and a frequency range of DC to 30,500MHz. The LFCN features a good stopband rejection due to a strategically constructed layout with minimal interaction between components. Mini-Circuits LFCN LTCC Low Pass Filters can handle up to 1W RF input power, provide 1.2dB to 1.9dB typical passband insertion loss, and have a -55°C to +125°C operating temperature range.

Feature Benefit Bullets

No. of Terminals: 4

Having 4 terminals allows for easy and secure connection in the circuit, ensuring reliable performance.

Filter Type: CERAMIC LPF

Ceramic Low Pass Filter (LPF) provides efficient filtering of high frequency signals, making it ideal for applications requiring noise suppression.

Attenuation At Maximum Frequency: 40 dB

High attenuation at the maximum frequency ensures that unwanted signals are effectively filtered out, improving overall signal quality.

Maximum Operating Temperature: 100 °C

With a maximum operating temperature of 100°C, this filter can withstand high temperature environments, increasing its versatility.

Minimum Operating Temperature: -55 °C

The ability to operate at temperatures as low as -55°C allows for reliable performance in a wide range of environmental conditions.

Minimum Attenuation Frequency (± Δf): 425000 kHz

Effective attenuation at low frequencies helps in filtering out unwanted signals at the early stages, improving overall signal integrity.

Terminal Finish: Matte Tin (Sn) - with Nickel (Ni) barrier

The terminal finish provides a durable and corrosion-resistant surface for reliable connections, ensuring long-term performance.

Width (mm): 1.6

With a compact width of 1.6mm, this filter can be easily integrated into tight spaces or densely populated PCBs.

Maximum Insertion Loss: 3 dB

Low insertion loss ensures minimal signal degradation during filtering, preserving the quality and strength of the desired signals.

Center/Cutoff Frequency (fo/fc): 2125 MHz

The center/cutoff frequency of 2125 MHz indicates the range of frequencies that can be effectively filtered, making it suitable for specific signal processing requirements.

Voltage Standing Wave Ratio: 1.2

A low VSWR of 1.2 indicates efficient transmission of signals without reflections, ensuring optimal performance in high-frequency applications.

Length: 3.2 mm

The compact length of 3.2mm allows for efficient space utilization on the PCB, enabling compact and streamlined circuit designs.

Minimum No. of Sections: 7

Having a minimum of 7 filter sections allows for precise tuning and customization of the filtering characteristics, catering to specific application requirements.

Maximum No. of Sections: 7

A maximum of 7 filter sections provides the flexibility to achieve optimal filtering performance without unnecessary complexity, ensuring simplicity in design and implementation.

Average Input Power: 10 W

With an average input power handling capacity of 10W, this filter can effectively manage high-power signals without performance degradation, ensuring reliable operation.

Mounting Type: SURFACE MOUNT

The surface mounting type offers easy and secure installation on the PCB, simplifying the assembly process and ensuring stable connections.

I/O Impedance: 50 OHM

Matching the filter's impedance to the system's input/output impedance ensures efficient signal transfer and minimizes loss, optimizing overall system performance.

Dimensions: L3.2XB1.6XH0.94 (mm)/L0.126XB0.063XH0.037 (inch)

The compact dimensions of 3.2mm length, 1.6mm width, and 0.94mm height make this filter suitable for space-constrained applications while offering versatility in mounting options.

Maximum Attenuation Frequency (± Δf): 875000 kHz

High attenuation at the maximum frequency range of 875000 kHz ensures effective filtering of unwanted signals, enhancing the overall signal quality.

Attenuation At Minimum Frequency: 20 dB

Even at the minimum frequency range, the filter provides significant attenuation of 20 dB, ensuring consistent and reliable performance across different frequency bands.

Height: 0.94 mm

The low profile height of 0.94mm enables the filter to be easily integrated into compact electronic devices or systems, without compromising on performance.
