ECS-36-20-5PX-TR 3.6864 MHz SMD Crystal For Compact Timing

ECS-36-20-5PX-TR is a good fit for designs that need a common serial-friendly frequency in a small SMD crystal package. It runs at 3.6864 MHz with a 20 pF load rating, making it useful for UART timing, divider chains, and general embedded clocking where frequency planning is tied to standard baud rates. ECS-36-20-5PX-TR is specified at ±30 ppm tolerance and ±50 ppm stability over -10°C to 70°C, which supports consistent timing across typical equipment environments. The ESR is listed at 150 Ω, so it’s important to follow the target IC’s recommended drive level and loading values. Keep the crystal loop short, match trace lengths, and place load capacitors close to the oscillator pins to limit stray capacitance. Request a quote for ECS-36-20-5PX-TR.
