RF3210

Overview

The RF3210 is a Surface Acoustic Wave (SAW) filter manufactured by Murata Electronics, designed for narrowband signal conditioning applications. It operates at a center frequency of 303.825 MHz with a bandwidth of 700 kHz. The component exhibits an insertion loss of 1.7 dB and is housed in a TO-205AD (TO-39-3) metal can package. This through-hole device supports high-frequency wireless RF filtering requirements.

Feature Summary

• Surface Acoustic Wave technology for precise frequency selection
• Narrowband filtering capability centered at 303.825 MHz
• Robust metal can construction for environmental protection

Applications

• Wireless RF signal conditioning
• Narrowband communication systems
• Frequency-specific filtering circuits

Procurement Notes

Verify the specific manufacturer designation, as Littelfuse also utilizes the RF3210 prefix for PPTC resettable fuses. Confirm the component is a SAW filter from Murata Electronics rather than a Littelfuse fuse. Check availability status, as some sources indicate this part may be obsolete. Ensure the TO-205AD package matches design requirements.

Selection Notes

Select this component for applications requiring a fixed 303.825 MHz SAW filter with low insertion loss. The TO-205AD through-hole package dictates board layout constraints. Consider the 700 kHz bandwidth relative to signal requirements. Verify compatibility with existing circuit impedance and operating frequencies before integration.

Part Context

This component belongs to Murata's lineup of passive RF filters. SAW filters like the RF3210 are utilized where sharp frequency response and compact size are necessary. The metal can package provides shielding and durability compared to surface-mount alternatives.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to potential obsolescence indicated by some distributors, verify current manufacturing status and seek equivalent SAW filters with matching 303.825 MHz center frequency and TO-205AD package if direct replacement is required.
