CHPFL-0100

Overview

The CHPFL-0100 is a high-pass filter from the Crystek Corporation CHPFL series, designed for signal conditioning applications. It features a 7th order Butterworth response with a cutoff frequency of 100 MHz and operates within an impedance of 50 Ohms. The component supports a power handling capacity of 4 W and functions reliably across a temperature range of -40°C to +85°C. This inline filter is available in rugged SMA or BNC connector configurations, ensuring compatibility with standard RF test and measurement setups.

Feature Summary

• Provides steep attenuation characteristics through a 7th order Butterworth response design
• Engineered for robust performance in demanding environments with wide operating temperature tolerance
• Offers flexible integration options via standard SMA or BNC connector interfaces

Applications

• RF test and measurement equipment filtering
• General laboratory signal conditioning
• High-frequency circuit protection against low-frequency interference

Procurement Notes

Verify the specific connector type required for your application, as the base model designation may correspond to either SMA or BNC variants depending on the suffix. Confirm that the 4 W power rating aligns with your system's maximum input levels. Ensure the 50 Ohm impedance matches your transmission line requirements to prevent signal reflection issues during operation.

Selection Notes

Select this component when a sharp roll-off is necessary above 100 MHz while maintaining low insertion loss in the passband. Consider the physical connector interface (SMA vs. BNC) based on existing cabling infrastructure. Evaluate the thermal environment to ensure it remains within the specified -40°C to +85°C operational range for long-term reliability.

Part Context

This part belongs to the Crystek CHPFL series of high-pass filters, which are characterized by their rugged housing and compliance with RoHS standards. The series includes various cutoff frequencies, allowing engineers to tailor frequency rejection profiles for different RF applications without compromising signal integrity in the desired band.

Replacement Considerations

Direct substitutes include other models within the Crystek CHPFL series with similar cutoff frequencies, such as the CHPFL-0050 or CHPFL-0300, provided the connector type and impedance remain compatible. Cross-brand replacements require careful verification of the 7th order response curve and power handling capabilities.
