WF5025 series

Crystal Oscillator Module ICs

OVERVIEW

The WF5025 series are miniature crystal oscillator module ICs. They feature a damping resistor R matched to

the crystal's characteristics to reduce crystal current. The pad layout is arranged for ﬂip chip mounting, which

gives the pattern design more ﬂexibility, even for mounting ultra-miniature crystal oscillators that provide

almost no space for wiring patterns. They support fundamental oscillation and 3rd overtone oscillation modes.

The WF5025 series can be used to correspond to wide range of applications.

*1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscil-

lator frequency band is not guaranteed. Speciﬁcally, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the

oscillation characteristics of components must be carefully evaluated.

*2. The WF5025BL1 has a higher maximum operating frequency, hence the negative resistance is also larger than in the WF5025AL× devices.

Note. These versions in parentheses ( ) are under development. Please ask our Sales & Marketing section for further detail.
