SDR315M500S012

Overview

The SDR315M500S012 is a Surface Acoustic Wave (SAW) resonator manufactured by NextGen Components. It operates at a nominal frequency of 315.5 MHz with a frequency tolerance of ±75 kHz. The device features a single-port configuration and a maximum insertion loss of 2.0 dB. It utilizes a 6-pad surface mount package measuring 3.0 mm in length, 3.0 mm in width, and 1.25 mm in height. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for stable resonance
• Designed for compact surface-mount integration
• Single-port architecture simplifies circuit design

Applications

• RF signal generation circuits
• Wireless communication modules
• Industrial control systems requiring precise timing

Procurement Notes

Verify the specific package dimensions and pin configuration against the official datasheet before integration. Confirm that the ±75 kHz tolerance meets the system requirements. Ensure the operating temperature range aligns with the environmental conditions of the final application. Cross-reference the part number to avoid confusion with similar series variants.

Selection Notes

Select this component when a 315.5 MHz reference is required in a space-constrained design. Consider the 2.0 dB insertion loss limit for power efficiency. Evaluate the thermal stability across the specified temperature range. Compare against other SAW resonators if tighter frequency tolerances are necessary.

Part Context

This part belongs to the SDR series of SAW resonators from NextGen Components. It shares the same physical footprint as other models in the series but differs in frequency and tolerance specifications. The series is designed for general-purpose RF applications requiring reliable performance in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include the SDR315M000S011, which offers a tighter ±50 kHz tolerance. Other variants within the SDR series may provide different frequencies or pad counts. Verify electrical compatibility before substitution.
