Product Description

The plastic moulded surface mount package of the GSX-200 is a fully compatible drop in replacement for MC-306, DMX-26S, FSRLF, E1WS, SMQ32SL, RSM200S and other industrial standard plastic-package crystals.

The ideal part for use within existing designs where a footprint has already been designed, the GSX-200 offers highly competitive pricing and is available up to industrial operating temperature ranges.

For new designs we would recommend the GSX-315 with miniature surface mount footprint.
