■ 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 9 digits) k – Number for specifying an order
Example 1:When ordering a product with model name: NZ2520SB, frequency: 32.768kHz, overall frequency tolerance: ±30 x 10–6,
and supply voltage: 1.8 V
Ordering Code: NZ2520SB – 32.768000K – NSA3534C
Example 2:When ordering a product with model name: NZ2520SB, frequency: 32.768kHz, overall frequency tolerance: ±30 x 10–6,
and supply voltage: 3.3 V
Ordering Code: NZ2520SB – 32.768000K – NSA3536C
If you have any queries concerning our standard frequencies and numbers for specifying orders, please contact our sales representatives
or visit our homepage (http://www.ndk.com/).
