■ How to Specify an Order
When ordering our products, specify them with an “Ordering Code” that consists of the following:
Model name
–
Frequency
(up to 8 digits)
M – Number for specifying an order
Example :When ordering +2.5 V, Max. ±100×10-6/0 to 85 °C, 156.25 MHz
Ordering Code: 7311S-GF-104X-156.25M-NSA3346B
