It’s size makes it suitable for high density circuit boards or applications where space is limited and the tape and reel packaging means that it is ideal for automatic placement machines. The heart of the device is a heat resistant cylinder type crystal which gives it high stability characteristics sufficient to allow reflow soldering. The epoxy based encapsulation makes it less porous than the ACT200 and, therefore, better suited to post reflow washing -20 -10 0 +10 +20 +30 +40 +50 +60 -10 -20 -30 -40 -50 -60 Δf/f (ppm) Temperature °C Typical Temperature Characteristics Suggested Footprint 8.7 max 3.7 max 5.5 2.5 max 4.2 1.3 1.8 1.0 Dimensions in mm Issue : 4 I3 Date : 17/08/04 2 of 2
