HFCN-440+

Overview

The HFCN-440+ is a high-pass filter manufactured by Mini-Circuits, utilizing low-temperature co-fired ceramic (LTCC) technology. It features a cutoff frequency of 440 MHz and operates with a standard 50 Ohm impedance. The device is housed in a compact SMD package, specifically the FV1206 form factor, designed for board mount applications. It supports surface mount assembly and functions within a temperature range of -40°C to +85°C. The component exhibits an insertion loss of up to 3 dB, ensuring efficient signal transmission while effectively suppressing frequencies below the specified cutoff point.

Feature Summary

• Utilizes LTCC technology for stable performance and compact size
• Provides effective suppression of low-frequency interference and harmonics
• Designed for precise impedance matching in RF circuits

Applications

• Multi-band RF filtering designs in wireless devices
• RF test equipment signal conditioning

Procurement Notes

Verify the specific datasheet version for the HFCN-440+ to confirm exact electrical tolerances and mechanical dimensions before integration. Ensure compatibility with the target PCB footprint, which corresponds to the FV1206 package style. Cross-reference the manufacturer's official documentation for any updates regarding material compliance or recommended soldering profiles to guarantee reliable long-term operation in the intended application environment.

Selection Notes

Select this component when a sharp cutoff at 440 MHz is required for high-pass filtering applications. The LTCC construction offers advantages in thermal stability and miniaturization compared to traditional ceramic filters. Consider the 50 Ohm system impedance requirement and the maximum insertion loss specification when designing the signal chain. This part is suitable for environments requiring robust performance across a wide operating temperature range.
