The Geyer Electronic America, Inc. model 12.95538 is a standard crystal oscillator (XO) operating at a frequency of 27.12 MHz. It is housed in a compact 4-SMD, No Lead package with dimensions of 0.098 inches in length and 0.079 inches in width, equivalent to 2.50 mm by 2.00 mm. The component is supplied in tape and reel packaging for automated surface-mount assembly.
Verify the specific ordering suffix and voltage requirements against the official datasheet before procurement. Confirm that the 4-SMD no-lead package footprint matches the target PCB design. Ensure compatibility with reflow soldering profiles specified by the manufacturer to maintain component integrity during assembly processes.
Select this component when a precise 27.12 MHz timing reference is required in space-constrained designs. The small 2.50mm x 2.00mm footprint makes it suitable for dense circuit layouts. Consider the standard XO type for general-purpose clocking needs where high stability or low phase noise specifications are not explicitly mandated by the system architecture.
This part belongs to the family of quartz crystals, oscillators, and resonators manufactured by GEYER Electronic. As a leading provider of frequency control products, the company offers various solutions for timekeeping and signal generation. This specific model represents a standard surface-mount oscillator option within their broader portfolio of precision timing components.
Cross-reference with other 27.12 MHz 4-SMD oscillators from different manufacturers if supply constraints exist. Verify pinout compatibility and electrical parameter alignment before substituting with alternative brands to ensure seamless integration into existing designs without requiring layout modifications.
