SLFL21-2R025G-01TF

Overview

The SLFL21-2R025G-01TF is a ceramic low-pass filter from the SLFL21 series, manufactured by Shenzhen Sunlord Electronics Co., Ltd. It features a cut-off frequency of 2025 MHz and a bandwidth of 1880-2025 MHz. The device exhibits a maximum insertion loss of 1.3 dB. It provides attenuation of at least 20 dB in the range of 2300-6100 MHz and at least 30 dB beyond that spectrum. The component is designed for surface mount technology in an 0805 package.

Feature Summary

• Passive low-pass filtering capability with defined cut-off characteristics
• High attenuation performance in stopband frequencies
• Compact surface mount construction suitable for space-constrained designs

Applications

• RF signal path filtering in wireless communication modules
• Noise suppression in cellular handset front-end circuits
• Frequency selection in broadband receiver architectures

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Shenzhen Sunlord Electronics Co., Ltd. before procurement. Confirm that the 0805 package dimensions and termination materials match your PCB layout requirements. Ensure the operating temperature range aligns with your system's environmental specifications. Cross-reference the part number suffix to confirm exact electrical tolerances and packaging format.

Selection Notes

Select this component when a sharp roll-off near 2 GHz is required with minimal passband distortion. The 1.3 dB insertion loss makes it suitable for sensitive RF chains where signal integrity is critical. Consider the physical size constraints of the 0805 footprint during board design. Evaluate the stopband rejection levels against specific interference sources in the 2.3 GHz to 6.1 GHz range.

Part Context

This part belongs to the SLFL21 series of multilayer chip ceramic filters produced by Sunlord. The series targets RF applications requiring compact, high-performance filtering solutions. Sunlord specializes in passive components including magnetic devices and microwave components for communications and consumer electronics markets.
