–6
.
Ultralow Power-Driven Type
■
Application
● For Portable equipment (ex. Mobile Phone, Digital Media Player, PND,
Notebook PC, etc)
■
Features
● Ultralow power-driven (0.8V min) crystal clock oscillator, ideal for mobile devices.
● Compact and light. Dimensions : 2.5 x 2.0 x 0.9 mm, weight : 0.02 g.
● This crystal clock oscillator can support low frequencies (from 1.0MHz) not
easily achieved with crystal units of the same size.
● Taped units enable automatic mounting and IR Reflow (lead free) is possible.
● Lead-free.

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) M – Number for specifying an order
Example 1: When ordering a product with model name: NZ2520SF, frequency: 20 MHz, overall frequency tolerance: ±30 x 10
–6
,
and power supply voltage: 0.9 V
Ordering Code: NZ2520SF – 20.000000M – NSA3468C
Example 2: When ordering a product with model name: NZ2520SF, frequency: 20 MHz, overall frequency tolerance: ±30 x 10
–6
,
and power supply voltage: 1.5 V
Ordering Code: NZ2520SF – 20.000000M – NSA3469C
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/).
