RFLPF2012090K0T

Overview

The RFLPF2012090K0T is a ceramic low-pass filter manufactured by Walsin Technology Corporation, designed for RF applications in the 5 GHz ISM band. It operates at a nominal impedance of 50 Ohms and utilizes an 0805 (2012 metric) surface-mount package. The component features a maximum insertion loss of 0.65 dB, ensuring efficient signal transmission within its passband while attenuating higher frequencies.

Feature Summary

• Engineered specifically for 5 GHz ISM band RF applications
• Utilizes ceramic construction for stable signal conditioning
• Optimized for minimal signal attenuation with low insertion loss

Applications

• Wireless LAN modules operating in the 5 GHz spectrum
• ISM band communication devices requiring RF filtering
• Signal conditioning circuits in compact mobile electronics

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Walsin Technology or authorized distributors before procurement. Ensure that the 0805 footprint matches the target PCB design constraints. Confirm that the 50 Ohm impedance rating aligns with the system's transmission line requirements to prevent signal reflection issues during integration.

Selection Notes

Select this component when designing circuits for the 5 GHz ISM band that require a compact, low-loss solution. The 0805 package size offers a balance between performance and board space efficiency. Consider the 0.65 dB insertion loss specification when calculating total link budget margins for sensitive RF front-end architectures.

Part Context

This part belongs to the RFLPF series of ceramic low-pass filters from Walsin Technology. These components are widely used in modern wireless communications to suppress out-of-band noise and harmonics. The series provides reliable signal integrity for high-frequency applications where small form factors are critical.

Replacement Considerations

Check for direct substitutes such as the RFLPF2012090K0T variants or other 0805 5 GHz low-pass filters from Walsin. Verify pin compatibility and electrical specifications like cutoff frequency and insertion loss before substituting.
