FSR-5035 SMD SAW Resonator (5.0×3.5 mm)

FSR-5035 is a compact SAW resonator designed for high transmit/receive sensitivity and robust environmental resistance (high-temperature resistance and impact resistance). It supports 154–1000 MHz and common sub-GHz ISM frequencies such as 315 MHz, 433.92 MHz, 868 MHz, and 915 MHz. Learn more about SAW Resonator.

Package & Pinout

Item	Details
Package Size	5.0×3.5×1.5 mm (SMD)
Pin Assignment	Pin 1: Input/Output Pin 3: Output/Input Pins 2, 4: Case Ground
Layout Guidance	Use a continuous RF ground reference. Connect case-ground pins to low-impedance ground with short vias. Keep RF routing short and avoid stubs.

Note: Pin 1 and Pin 3 are bidirectional depending on circuit topology. Case-ground pins should be stitched to a solid RF ground plane.

Design Recommendations

Ground first: prioritize a low-impedance RF return path; place multiple ground vias near case-ground pins.
Short RF interconnect: minimize line length between the resonator and RF IC/network; avoid dangling stubs.
EMI isolation: keep away from high-speed clocks and switching regulators; maintain clean reference ground.
Thermal robustness: confirm tolerance target across temperature for your end system (−40 to +85°C).
Custom options: if you need a special frequency/tolerance, share target MHz and kHz requirement via email.
