www.DataSheet4U.com WF5025 series Crystal Oscillator Module ICs OVERVIEW The WF5025 series are miniature crystal oscillator module ICs. They feature a damping resistor RD 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 osc.

www.DataSheet4U.com WF5025 series Crystal Oscillator Module ICs OVERVIEW The WF5025 series are miniature crystal oscillator module ICs. They feature a damping resistor RD 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.

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