How to Specify an Order

Example 1: When ordering a product with model name: 2570NK, frequency: 20 MHz,

–6

frequency stability: 100 x 10 , and power supply voltage: 5.0 V

When ordering our products, specify them with an “Ordering Code” that consists of the following:

Ordering Code: 2570NK – 20.000000M – NSA3285B

–
